1 METAL TUBE VARIABLE AREA FLOWMETER AM9000 Series GENERAL The AM9000 series metal tube variable area flowmeters have the unified face-to-face dimension mm. Having developed the current well-accepted AM7000 series, the AM900 has a compact and unified construction which makes piping design simpler and saves installation space, leading to a low engineering cost. In addition to highly reliable mechanical local indicator, a variety of standard-equipped functions such as electric transmission, local flow integration and integrated flow transmission by pulse, alarm, and digital communication of these data can meet your various requirements. The AM9000 covers liquid, gas and steam measurement in various fields. FEATURES FULL LINE-UP TO MEET ALL POSSIBLE REQUIREMENTS!! All the necessary functions required for variable area flowmeter, i.e. local indication, electric transmitters, local flow integration, PROFIBUS PA & HART communication, integrator with scaled pulse output and alarm are now available from one line. COMPACT DESIGN Smaller and lighter To suit modern needs. Unified face-to-face dimension mm makes piping design easier. WIDE PRESSURE RANGE 0 lbs and 00 lbs rating are available as standard and higher pressure versions are also available as option.

14 ADDITIONAL FUNCTION GAS DAMPER (Model AM9 /DU) All flowmeters with their meter sizes ranging from to 00 mm for gas measurement are equipped with gas dampers as standard. Mechanical damper is integrated at the part of float guide which consists of piston and cylinder. As it is not required to install liquid damper at the bottom of flowmeters, it contributes to increase the flexibility of piping design. Also it is not required to fill damper liquid that saves maintenance labour works. Gas damper is applicable for gas and steam measurement applications and not suitable for liquids. Also chlorine gas (easy to form chemical compound) and gas containing rust, trash and oil may hinder the function of piston part.

15 SELECTION OF FLOWMETER. LIQUID APPLICATION a. Selection of meter size The maximum flow rate of each meter size is shown in "DIMENSIONS, MATERIAL, PRESSURE DROP, FLOW RATE TABLE." These fig ures are based on water flow (Density.0g/cm and Viscosity.0MPa s). If actual fluid condition is different from such figures, a conversion calculation is required as following formula: Qw = Q.9 / (7.7/ ρ ) - Qw : Water converted flow rate (m /h) Q : Flow rate of actual fluid (m /h) ρ ; Density of actual fluid (g/cm ) Example Fluid: Alcohol Density: 0.8g/cm Flow rate: 0m /h Flowmeter to be used: AM9 Qw = 0.9 / (7.7/0.8) - = =. m /h You will find required meter size to be 80 which covers above converted flow rate from table. Please refer to "AVAILABLITY OF CON- NECTION SIZE" for the possible connection size applied for the required meter size. Consult TOKYO KEISO Co., Ltd. for high viscosity services. b. Slurry application For slurry services such as liquids containing precipitates, particles, sands, the flowmeters suitable for slurry liquids are available. Consult TOKYO KEISO Co., Ltd. for details.. GAS APPLICATION Use the flowmeter with a gas damper unless otherwise specified to avoid a hunting, model AM9 /DU. Selection of meter size The flow rate of air in table (rated flow rate table) for AM9 /DU with a gas damper is the one converted into the unit of m /h (nor) from the flow rate of air which is measured at the conditions of 0ºC and atm. If actual fluid condition is different from such figures, a conversion calculation to be performed by the following formula: QA = Q 0.0 ρ (7+t) / (0.0+p) QA : Converted flow rate in air 0C, atm [m /h(nor)] Q : Flow rate of gas to be measured [m /h(nor)] ρ : Density of gas to be measured [kg/m (nor)] p : Pressure of gas to be measured (MPa) t : Operating temperature ( C) Example Gas to be measured : Nitrogen (N) Density ( ρ ) :.kgf/m (nor) Operating pressure ( p ) : 0.MPa Operating temperature ( t ) : 0 C Flow rate of gas to be measured (Q) : 00 m /h(nor) Flowmeter with a gas damper to be used : AM9 /DU QA = (7+0) / (0.0+0.) = =. m /h (nor) You will find required meter size to be which covers above converted flow rate from table.

16 . STEAM APPLICATION Use the flowmeter with a gas damper unless otherwise specified to avoid a hunting, model AM9 /DU. Selection of meter size Steam flow rate is to be converted into air flow rate by the following formula for size determination. QA = Qs 0.89 ρ QA : Air flow rate at 0 C, atm converted from steam [m /h(nor)] Qs : Steam flow rate (m /h) ρ : Density of steam (kg/m ) Example Fluid : Saturated steam Pressure : 0.9MPa Flow rate : t/h Flowmeter with a gas damper to be used : AM9 /DU First, density of the steam is to be obtained from Steam graph etc. In this application, density(ρ) of 0.9MPa steam is.kg/m. Saturated steam curve (by temperature) is shown in the figure below and saturated steam curve (by pressure) is on Fig. 0 for reference. Normally, flow rate of steam is described in weight unit, which is to be converted to volume unit (Qs) as follows: QA = = 9.97 = 7 m /h (nor) You will find required meter size to be 0 which covers above converted flow rate from table. Please refer to "AVAILABLITY OF CONNECTION SIZE" for the possible connection size applied for the required meter size.

18 CAUTIONS This flowmeter transmits the displacement caused by the magnet coupling. A surrounding magnetic field might affect its performance. Avoid installation near magnetic fields. Magnetic materials including insulation covers may also affect its performance; do not bring them within 0 cm from the flowmeter. When installing two or more flowmeters, place them at least the distances shown in the figures below apart from each other to avoid mutual interference. For maintenance, ensure a clearance of at least 0 cm between the indicator of one flowmeter and the body of other flowmeters. Local indication and alarm output type Electric transmitter and PROFIBUS PA type Local integration type For a meter size of 0 or less: at least cm For a meter size of or more: at least cm For a meter size of 0 or less: at least cm For a meter size of or more: at least cm For a meter size of 0 or less: at least 0 cm For a meter size of or more: at least 0 cm At least 0 cm At least 0 cm At least 0 cm * Specification is subject to change without notice.
