3 Page 3 of APPLICATION Battery-powered ultrasonic water meters of the FLOMIC FL 102X type series are intended for technological measurements of instantaneous flow rate and consumption in water-supply networks, and archiving of the measured data. Measurement of water pressure in piping is also possible. The technical capabilities including high measurement accuracy and long-term stability over a wide range of measured values make it possible to use the meters, apart from the conventional measurements, for monitoring leakage and the general condition of water supply networks. The FLOMIC FL 102X water meters do not require external power, do not include any moving parts or filters to prevent choking with mechanical impurities and, compared to conventional water meters, have significantly lower hydraulic losses. Regarding other types of fluid including explosive or flammable liquids, compliance is required with the specifications in the product manual or writing approval of the flow-meter manufacturer. Flow meters shall be used in standard non-explosive environments. Any installation of water meter must be in conformity with technical conditions mentioned in this manual. 2. MEASUREMENT METHOD The measurement method used is a single-beam impulse transit-time method based on determination of the time needed for an ultrasonic impulse wave to cross the distance between two probes embedded in piping. Each of the probes functions as the sender and receiver in turns so that the ultrasonic wave travels in turns in and against the water flow direction. This arrangement allows for effective elimination of errors due to asymmetry in the probe locations. 3. TECHNICAL DESCRIPTION 3.1. Meter characteristics The FLOMIC FL 102X ultrasonic water meter is an electronic device used to measure the water flow rate in a fully flooded piping. It is manufactured and supplied in two versions: compact and distributed. The compact version, designated FL 1024, has the electronic unit attached directly onto the flow sensor housing. An optional accessory is equipment for water pressure measurement and data storage. Instantaneous pressure values can be indicated within the range of 0 to 10 bar. The distributed version, designated FL 1025, has the electronic unit separated from the sensor and connected with it by means of a cable (max. length 5m). The electronic unit is accommodated in a separate box that can be fitted on a wall. In the standard configuration, the meter software allows for measuring and display of the instantaneous flow rate and total volume of water passed through the meter since the volume counter was last reset. The meter is provided with a passive impulse output including an optocoupler. The impulse length is 50ms; on customer s request, it can be set at 2ms. Optional meter accessories include passive current output, pressure gauge function, data storage, the RS 232 communication line (plus a GSM module, if required), the M-Bus communication interface, and meter reading via an optical interface. On request, the meter can be supplied in a version suitable for use in drinking-water supply systems; the separate sensor unit can have the protection class of IP 68.

MPa l/imp CURRENT OUTPUT PRESSURE RANGE ma bar warranty void if removed Electronic unit The electronic unit and battery are placed in an aluminium box with a plastic lid. The box is provided with a special valve preventing moisture condensation inside the box and up to three grummets for cables of circular cross-section. The surface finish is by paint of orange hue (RAL 1017). Two M8 grummets are intended for cables of outside diameter 3.5 to 5mm to be connected to the selected output signal terminals. On delivery, these grummets are blinded. The third grummet (M12) is provided only in the case of the distributed meter version and is intended for the cable of diameter 6.5 to 8mm connecting the sensor and the remote electronic unit. The connecting cable is supplied attached to the electronic unit with the other end ready to be connected to the sensor terminal board. In the IP 68 design version of the sensor, the connecting cable is attached to both the sensor and electronic units and cannot be disconnected. The meter display is located under the transparent plastic cover. The push-button on the unit box is used to select the desired display mode: either instantaneous flow rate (in m 3 /hod or gallons per minute GPM), the total fluid volume (in m 3 or thousands of gallons) passed through the meter sensor since the volume counter was last reset, or the fluid pressure (in bar). The actual quantity displayed is indicated at the bottom line by the symbol. In the case of a meter failure, the respective error message (E1 through to E5) will be indicated by the same symbol - see the picture below. A recess in the unit box is for an optical probe to be applied onto the recessed surface to read the stored data. Also found under the box lid is the meter rating plate:

12 Page 12 of 28 There are no limitations regarding sensor position in piping; however, consideration should be given to the ease of reading the display data and access to the optical probe contact point (see the picture below). 360 The above recommendations regarding the meter/sensor placement and installation apply to both the compact and distributed meter versions Meter installation General recommendations In the basic arrangement (flow direction from left to right and the sensor installed into a horizontal piping section), the electronic unit is fitted onto the sensor body as shown in the following picture. 3 3 E1 E2 E3 E4 E5 bar m m/h FLOMIC FL 1024 TCM 142/ IP 67 DC 3,6V T C FLOW DIRECTION

13 Page 13 of 28 In the case of vertical mounting, or the flow direction from right to left, the electronic unit can be rotated with respect to the sensor body by 90 or 180 in both ways; 180 rotation is a limit to avoid straining the connecting wires. The unit can be rotated upon loosening the arresting screw M5 at the unit base using an Alien wrench, size 2.5mm. The 90 positions on the unit base are marked by recesses for the arresting screw. With commercial (invoicing) meters, the arresting screw is provided with a seal so that the position of the electronic unit cannot be modified VIEW P E1 E2 E3 E4 E5 bar 3 3 m m/h FLOMIC FL 1024 TCM 142/ IP 67 DC 3,6V T C P lock screw FLOW DIRECTION To prevent signal interference, the meter wiring shall be placed at least 25cm away from any live power cables. The interconnection between the meter sensor and electronic unit (the distributed meter version) is made by a shielded cable with the shielding connected to the earth potential at the sensor terminal board. It is recommended that all output signals (the impulse, current and M-Bus outputs) be connected using shielded cables with the shielding connected to the earth potential on the side of the plant control system. The meter sensor shall also be carefully earthed. To do that, connect the grounding bolt on the sensor flange with the piping flanges using an earthing conductor of cross-section of at least 4mm 2. 2 min 4mm -green and yellow wire insulation FLOMIC FL 1024 EN TCM 142/ IP 67DC 3,6V T C

The terminal board can be accessed upon removal of the plastic lid at the top of the unit box. The lid is secured in position by means of two M4 screws with hexagonal socket heads for Alien wrench size 2mm. At the bottom side of the plastic lid there are two slots 8mm wide where a flat tool can be inserted to help lift the lid from the box. It is recommended to insert a screwdriver into one of the slots and slightly pry upwards. The locations of the slots are shown in the picture below. Prior to replacing the lid, apply a thin layer of glycerine or silicon oil on the sealing O-ring. When replacing the lid, the 3mm hole at the bottom side of the plastic lid should be fitted onto the guide pin of diameter 2.5mm press-fitted at the box bottom.

OPERATIONAL START The water meter is delivered calibrated and in a fully operative condition. Once it is fitted into the selected metering point in the piping, bled and filled with the technological fluid, it is ready for operation. The condition of readiness to start is indicated by disappearance of the error messages at the bottom of the meter display unit. Using the control pushbutton, check the selection of measurement modes: the instantaneous flow rate, total volume passed and pressure (if applicable).

19 7. OPERATION Page 19 of Reading the measured quantities from the meter display The eight-character display unit can show either the instantaneous flow rate in m 3 /hour (or G/min), the total volume of the fluid passed through the meter sensor since the reading was last reset, in m 3 (or in G.10 3 ), or the fluid pressure (provided the meter assembly includes a pressure gauge). The reading of instantaneous flow rate has a certain delay as the displayed value is determined as the arithmetic average of the six latest measurements (each taken in 1-second intervals). So calculated values also appear at the meter outputs. The delay becomes noticeable in the cases of rapidly changing (growing or falling) flow rate. Meter errors will be indicated on the display. Due to the limited power capacity of the meter, the various display modes can only be selected in intervals of 1 second or longer. It is therefore recommended that the display mode selection push-button be always depressed for at least one second, and the next selection command be given after another 1 second or longer. Depending on the reading of the total fluid volume passed, the decimal point on the display will move as shown in the following picture. Display of pressure in bar- decimal point Displayed data in m (G.10 ) 3 3 Decimal point position for total volume less than ,000 m (G.10 ) Decimal point position for total volume greater than 10,000,000 m (G.10 ) 3 3 Decimal point position for total volume between Decimal point position for total volume between 3 1,000,000 m (G.10 ) and 10,000,000 m (G.10 ) ,000 m (G.10 ) and 1,000,000 m (G.10 ) 7.2. Electrical outputs Impulse output An impulse output is found on all FLOMIC FL water meters irrespective of their version or configuration. In includes an optocoupler connected to terminals 7 and 8 (terminal board X1); the permitted current loading is 10mA, the impulse length 50ms. On a customer s request the impulse length can be set at 2ms. If voltage impulses are required, use an external power source of 5 to 25 V DC connected in series with a limiting resistor so that the maximum current would not exceed 10mA. The interconnection of external power source and limiting resistor is shown in the picture illustrating the interconnections at the output terminal board (Section above). The impulse length can also be modified on site; for 50ms impulses, use jumper J5 to connect terminals J5:2 and J5:3 (X1), for 2ms impulses, connect terminals J5:1 and J5:2 (see the figure below). J X1

20 ELIS PLZEŇ a. s Current output Page 20 of 28 The current output 4 20mA is connected to terminals 5 and 6 at the output terminal board (X1). Upon attaining the output current level of 20mA (corresponding to Qmax), the current will not exceed this value and the error message E4 will appear on the display (see Section 7.5. below). To utilize the output current function, use an external power source of 10 to 24 V DC and the interconnection at the output terminal board as described in Section The maximum permitted resistance (the ohmic resistance of the cable + input resistance of the co-operating equipment) of the current output circuit shall be determined using the following formula: R s [Ω] = U source [V] Communication interface Communication via optical interface Via the optical interface the meter operator can read the actual measured data (instantaneous flow rate, total volume passed and pressure), the stored data of earlier operational periods, the parameters of the data archiving function and the error messages generated. The meter software programs allow for storage, at regular user-defined intervals, of the measured values of instantaneous flow rate, total fluid volume passed, fluid pressure, maximum and minimum values of instantaneous flow rates over the recent measurement period plus information on the times when such extreme values occurred. Apart from these data, stored can also be any error messages plus the times when these were generated. To be able to utilize the optical communication function, the meter software shall include the data-processing program ArchTerm for connection to a notebook or personal computer and an optical probe with a 1.5m cable including a connector to RS 232. The optical probe shall be applied to a recess on the electronic unit box with the correct position defined by an arresting pin; the probe is held in operating position by a permanent magnet Communication via RS 232 The communication via an RS 232 line uses the signals connected to terminals 1 to 4 (X1) by the signal cable. The data reading and archiving, reading of error messages and checking the parameters of the data archiving function can be done to the same extent as shown in Section above. It is also possible to connect a GSM module. The hardware used does not allow for modification to M-Bus communication Communication via M-Bus The communication system with an M-Bus interface uses the signals available on terminals 3 and 4 (X1) and allows for reading of the values of instantaneous flow rate and total volume passed. Modification to communication via RS 232 is not possible.

23 Error identification function Page 23 of 28 Meter errors shall be identified as E1 through to E5 by symbol shown at the bottom of the display unit. Error identification symbols: E1 - the ultrasonic signal cannot freely propagate in the sensor cavity (due to the presence of air or mechanical particles) E2 - too great a difference between the signal travel times in and against the fluid flow direction (possibly due to the presence of air at one of the probes, which may be a temporary condition during the operation of filling the piping with fluid, or due to contamination of the face part of one of the probes) E3 - A/D converter error (e.g. due to strong interference) E4 - flow rate in excess of q s E5 - flat meter battery Should the display go completely blank, check the battery condition (the voltage should be over 3V). Replace defective battery using the procedure described in Section 7.6. Should the battery replacement fail to restore the correct meter function, send the meter for repair to the manufacturer s service centre Battery life and replacement The battery lifetime in a meter of a standard configuration is 8 years, in a meter including various optional functions 6 years. The battery compartment is sealed with an assembly seal to indicate that battery replacement is reserved to staff who are authorised to remove and place/replace assembly seals on the meter components. While the battery is being replaced, all stored data including those on the total volume of fluid passed through the metering point are protected. The recommended battery brand is SAFT LITHIUM 3.6V/16Ah, type designation LS By customer request,electronic unit can be equipped with battery SAFT LITHIUM 3,6V /3,6Ah LSH 14 "light" (size C) containing less than 1g of lithium, equipped with plastic case assuring using of both C and D size battery in battery holder. Lifetime of LSH 14 "lite" battery is 1 year since date of production and can be replaced by battery SAFT LITHIUM 3,6V / 16Ah LS (size D). Plastic case is not used for D size battery LSH 14 "light" battery is used as a "transport battery," because it is non-restricted to transport/non-assigned to Class 9 according Lithium battery transport regulation (Ref. TC-LSH 14"light"-09/03-1). To replace the meter battery, first remove the plastic lid on the electronic unit box held in position by two M4 screws with hexagonal socket heads (use Alien wrench, size 2mm), see Section , then loosen three M3 bolts holding the electronic module in the aluminium box and pull the module outside the box. While doing that, make sure you do not damage any metrological or company seals. The electronic module can only be removed as far as probe conductors and output signal cables permit. The battery is located in a holder at the bottom of the unit; pull the battery free and replace it with a new one. Mind the correct polarity as indicated on a plate on the battery holder. Push the electronic module back into the box, tighten the holding bolts, replace the box lid, fix its position with screw and apply assembly seal on one of them.

CALIBRATION The FLOMIC ultrasonic water meters are supplied calibrated according to standard ISO so as to meet the precision requirements of class B (ISO ). The calibration method used is known as running start on scales automatic impulses where the beginning and end of the calibration test are given by output impulses from the water meter. On customer s request, more precise calibration can be performed. The standard calibration is done with respect to the impulse output. In that case the measurement error at the current output will be approx. 1% higher than that at the impulse output. If the customer requires calibration for the current output, it can be done and the additional error of about 1% will then appear at the impulse output. The water meter calibration activities can be performed by duly authorised service centres provided they have executed the necessary agreements with the meter manufacturer. In checking the meter functions, precision and in performing the calibration procedures, the measurement and test methods specified by standard ISO and the manufacturer s specification Es Z shall apply.
