Meter General Description The Max 210 Series Flow Meters are positive displacement piston type units capable of great accuracy over a wide range of flow rates and fluid viscosities. The four basic sizes of this series (213, 214, 215, 216) will measure flows from 1 cc/min to 25 gal/min. Various O ring and internal plating options are available to meet temperature and fluid compatibility requirements. inlet outlet In a piston type flow meter, four pistons and cylinders are arranged in a radial fashion around a central crankshaft. Two fluid ports on the cylinder wall, a port at the top of the cylinder, and a grooved piston enable fluid entering the flow meter s central cavity to be measured and pumped out by each piston in turn. The valving action for each cylinder is accomplished by the piston adjacent to it. The accuracy of a piston flow meter is dependent on close tolerances in the cylinder wall and piston. Max Machinery regularly holds tolerances as fine as 0.00005 inches in the production of these meters. The movement of the pistons is converted to a circular motion at the central crankshaft, which is coupled to a magnet in the flow meter. This motion is sensed by an external electronic transmitter, which converts flow into a voltage, pulse train, or current for further processing. The Max Series 210 Meter can be expected to perform superbly if operated within the confines of its design envelope. For this reason, it is important to read this manual and understand the operational requirements and limits of the meter. Our Technical Service staff will be happy to answer any questions that this manual does not cover. Max Model 214 Max Machinery, Inc. 210 Series User Manual Copyright 2012 Rev. #0312 4

Transmitter General Description Max transmitters are designed to work with the entire family of Max Flow Meters to provide extremely precise flow measurement in a cost effective package. Different options of industrial housings or IP66 rated explosion proof enclosures, combined with a choice of one-part and two-part, high temperature designs with remote electronics cover a wide range of application environments from the laboratory to harsh industrial processes. This latest generation of transmitters use modern sensor technology coupled with advanced signal processing to deliver high levels of performance and reliability. Hall sensors are used to detect the position of a driven magnet inside a Max Flow Meter. Changes in position are tracked by a microprocessor, which generates an output proportional to the flow rate. Advanced signal processing provides both fine angular resolution (0.36 degrees rotation) and rapid response (output updated every one millisecond). Max transmitters are typically mated to a mechanical flow meter, configured, and calibrated at the factory as a set. This ensures accuracy and allows quick setup in the field. For field installations where the transmitter has not been setup with a meter at the factory, an optional serial interface kit provides full access to configuration options and parameters. Transmitter Features High resolution measurement Analog Output: Configured output ranges to any value within ± 10 Vdc or ± 20 ma. Frequency Output: Configured output resolution of 1 to 1000 pulses per revolution. Linearization of up to 16 points to fully describe the flow meter s output curve and achieve the highest system linearity over the meter s entire operating range. Compensation Algorithm Compensates for variations in Hall sensor and flow meter characteristics to provide a stable, undamped output that accurately represents the instantaneous flow rate. This feature is factory set when the meter and transmitter are mated together. If the transmitter is changed, the compensation can be performed via a button on the circuit board. Anti-Dither Buffer - Masks the false output that may occur at very low flow rates in the presence of vibration or hydraulic noise. If the meter reverses direction the output signal will be interrupted for a user selected portion of a meter rotation. Reverse flow exceeding the buffer setting will result in an output proportional to reverse flow rate. The buffer quantity can be set from 1% to 100% of a revolution. 213 Standard 213 2-Part Pickup 213 Ex-Proof Max Machinery, Inc. 210 Series User Manual Copyright 2012 Rev. #0312 5

Do s & Don ts DO: Install bypass plumbing around the flow meter. This is useful during start up for removing dirt and air from the plumbing or when measuring fluid that may freeze inside the line and need to be remelted before it can pass through the meter. It also allows removing the flow meter for service without disabling the system. DO: Be very careful to keep parts clean during installation or teardown. A little dirt can look like a truckload compared to the 10 micron filtration requirement for series 210 Meters. DO: Clean the filter on a regular basis. DON T: Run water or aqueous solutions not approved by Max through your flow meter because of internal galling. DON T: Steam clean the meter (bypass or remove the meter if necessary). DON T: Blow down the meter with compressed air or gas because it may over-speed and damage the meter. DON T: Remove the Transmitter from the flow meter body. The transmitter is phased to the meter and a measurement error will result. Re-calibration will be necessary; see the transmitter interface software manual. DON T: Disassemble the flow meter. These are precision devices which require special tools and techniques. DON T: Turn on the pump in a system filled with material that is solid at room temperature. Wait until the material is completely melted and use the flow meter bypass valve during start up. DON T: Apply excessive differential pressure across the flow meter as it will cause internal failure (see the pressure drop curves for safe area operation). DON T: Over pressurize the meter. Maximum pressure is either 1,000 PSI (70 bar) 3,000 PSI (210 bar) or 7250 PSI (500 bar) depending on model purchased. DON T: Exceed the maximum flow rates for the material viscosity. DON T: Allow materials which solidify in air to set up in the flow meter. These may be impossible to remove. If the meter needs to be removed for repair and cannot be completely cleaned. Plug the inlet and outlet ports at once. Max Machinery, Inc. 210 Series User Manual Copyright 2012 Rev. #0312 9

Installation For optimum performance, install the flow meter in one of the configurations shown below. The following items and conditions should be considered: Line and Bypass Valves: These valves allow filter cleaning or flow meter removal without completely shutting the system down and draining the lines. They also allow system start up under conditions which could damage the meter; such as: air in the lines, high temperature materials, or initial line surges. Filtration: Clearances between the flow meter piston and cylinder wall are typically 0.0002 to 0.0004. Any dirt present in the system can jam or damage the unit. A 10 micron filter (such as a Max 381 Series stainless steel unit) is generally recommended, although materials with very high viscosities may require a coarser filter. For bidirectional flow applications, use a filter on each side of the flow meter. Materials with fibrous or non abrasive particulate matter may have to be run without filters. Follow the recommendation of your Max Sales Engineer or consult our Technical Service Department. Inlet and Outlet Ports: Use the IN port as the inlet for the most predominant flow direction. Install the flow meter on the discharge side of the pump whenever possible. Excessive vibration at the meter should be avoided. High Temperatures: Use the Vertical Installation drawing. This minimizes heat transfer by convection from the flow meter to the transmitter. The transmitter is the most heat sensitive element in the system and the transmitter manual should be consulted for specific limits. An optional fluid heater block can be used on the flow meter to keep it at operating temperature during standby conditions. For substances that are solid at room temperature, the block may be required to keep the material molten and flowing through the meter. Clean Plumbing: Before installing the flow meter, clean the inside of the pipe line with compressed air or steam (especially when using new pipe). Don t use water, steam, or compressed air on the meter itself!

Operation Determine that the following parameters of your flow metering system are within the specifications for the specific 210 Series Meter being used: Maximum System Pressure (Specifications) Differential Pressure across meter (Pressure Drop Curves) Maximum Flow Rate (Pressure Drop Curves) Metered Fluid Temperature (Sales specification, transmitter specifications page 7) If the metered fluid is greater than 80 F (28 C) over ambient, see the High Temperature Start Up section below. With valves (#1) and (#2) closed, slowly open valve (#3) (bypass) to clear the lines of foreign particles and air. Slowly open the inlet valve (#1). Slowly open the outlet valve (#2). Completely close the bypass valve. No routine maintenance, cleaning, or lubrication of the flow meter is required. A routine filter cleaning schedule should be established. The system should be shut down if abnormal noises occur or if unusual differential pressures across the meter are encountered. High Temperature Start Up: For fluids above 150 F (82 C) based on 70 F ambient, a special procedure is required to prevent thermal shock and permanent damage to the flow meter. The warm up time is determined by the equation below: TIME (minutes) = TIME (minutes) = connector size (inches) x (operating temperature ( F)-125) 10 OR connector size (inches) x (operating temperature ( C)-52) 10 Valves (#1) and (#2) must be closed. Open the bypass valve (#3) in gradual steps until the bypass piping is stabilized at operating temperature. Open valve (#1) slightly and allow the temperature to stabilize around the flow meter. Valve (#1) can then be opened completely. Open valve (#2) slightly. The flow meter may make unusual noises or bind at this point. Leave the valve at this setting until normal meter operation occurs, at which point valve (#2) can be gradually opened all the way. Slowly close the bypass valve (#3).

Electrical Installation - Wiring Removal note: The transmitter does not need to be removed from the flow meter for any field servicing or adjustments. Normally, the flow meter and transmitter are shipped back to the factory for calibration or service as a unit. If the transmitter needs to be removed from the flow meter for installation, be sure to retighten the transmitter snugly in order to ensure proper sensor alignment. Mechanical Installation 1. The transmitter is attached to the flow meter s threaded magnet shield. Hand tighten only. (~ 3 ft-lb) 2. The transmitter lid has four thread paths. To realign the cable, remove the lid and rotate up to 180 and retighten using an alternate starting point. Tighten to compress the O-ring seal. Removal 1. Remove electrical connections 2. Unscrew transmitter, using a wrench if necessary. WARNING Installation and removal should only be facilitated by trained personnel Verify transmitter output type (ANALOG or FREQUENCY) before wiring, inappropriate wiring could result in damaging the circuit. Moisture Seal Protection On all models, the housing is designed as a liquid and vapor-tight enclosure. There are O ring seals at the lid and possibly also the base of the housing these need to be fully seated. A properly sealed transmitter will prevent the formation of damaging moisture inside the housing. Turck connector Model: The connector is sealed to the lid at the factory and is ready for use. NPT Model: To ensure a moisture-tight seal, apply appropriate sealant to the threads at installation.

Installation Instructions Hazardous Locations Applies only to Max Model EX295 and EX296 Transmitters with explosion proof certification. These transmitters provide protection via a flame proof housing and through current limiting to the circuit board: Must wire with a class 2 power supply (See table for loads page 23). Meets US and Canadian Haz-Loc classifications, Class I, Div 1, Groups C and D, Tx As well as ATEX/IECEx II 2 G Ex d IIB Tx Gb Certification numbers Demko 11 ATEX 1013058X and IECEx UL 10.0048X Mechanical Installation The outer housing freely rotates to align the conduit hole with your electrical connection point. If the transmitter is already attached to the meter skip to step 5: 1. To attach the transmitter to the flow meter, apply a small amount of low strength thread adhesive, such as Loctite, on the threads and screw the transmitter onto the exterior threads on top of the flow meter. 2. Locate the locking set screw below the conduit hole and using a 3/32" hex wrench remove it. Rotate the outer housing clockwise until the screw hole lines up with a hole in the inner housing. (Inserting an Allen key into the threaded hole while rotating the housing can help in finding the point of alignment.) Now re-insert the set screw and handtighten it to lock the inner and outer housing together. 3. Finish tightening the transmitter onto the meter by applying a torque of 2 to 5 ft.-lb. (2.7 to 6.78 N-m). 4. Now back out the locking set screw until it is flush with the surface of the transmitter. 5. The housing can now be rotated to align the conduit port in the desired direction. 6. To remove the lid for wiring, remove the safety screw at the edge of the lid and then remove the cap using a 3/8 socket drive. 7. Install conduit. Within 18 of the housing install a conduit stop and fully seal with potting compound. 8. Connect wires to terminal block as shown below, using 2 mm screw driver. 9. A case ground terminal is provided internally, but if grounded metallic conduit is not used, then one of the external grounds below the conduit fitting must be used. For metric- use either a 6 or 8 mm long stainless steel M5 x 8.0 bolt. For inch measurement use either a 1/4 or 5/16 long stainless steel #10-32 bolt. 10. Reattach cap and tighten to 40 in-lbs to seal enclosure. Install safety lock screw at the edge of the lid and hand tighten. Max Machinery, Inc. 210 Series User Manual Copyright 2012 Rev. #0312 21

Removal from Flow Meter Note: the transmitter does not need to be removed from the flow meter for any field servicing or adjustments. Normally, the flow meter and transmitter are shipped back to the factory for calibration as a unit. 1. Remove the locking screw at the edge of the lid and then remove the cap using a 3/8 socket drive. 2. Disconnect wires at the terminal block and remove wiring conduit from transmitter. 3. Locate the locking set screw below the conduit hole and remove it. Rotate the outer housing clockwise until the screw hole lines up with a hole in the inner housing. (Inserting an Allen key into the threaded hole while rotating the housing can help in finding the point of alignment.) Now re-insert the set screw and hand-tighten it. This will lock the inner and outer housing together. 4. Unscrew the transmitter, using a strap wrench if necessary. Moisture Protection The housing is a liquid and vapor-tight enclosure certified to IP66. There is an O-ring seal at the lid of the housing the seal needs to be fully seated to provide moisture protection and achieve flameproof specifications. About Explosion proof installations For the Model 295 and 296 to fully adhere to the HazLoc certifications, the wiring must meet the appropriate codes. (Use of a wire conduit does not make the installation explosion proof read below.) The transmitters which are certified for use in hazardous locations require the use of a 1/2 NPT hazardous location rated conduit fitting. The wiring conduit must be sealed with a conduit stop within 18 of the device. If you choose to use exposed cables, cable seals must be used with sealing fittings and the wiring must be an approved armored cable. Electrical Installation Use wiring that is between 20 and 28 gauge and rated to at least 5 C above the maximum ambient temperature, and rated to at least 80% of the maximum fluid temperature.

For hot fluids, meter must be insulated and transmitter must be left exposed. All transmitters are rated to operate within the BLUE region, but only the remote sender unit variants (295-x5x-xxx) can operate up to the maximum temperatures shown in the chart. Consult factory for installation details when operating near temperature limits. Temperature class chart for all explosion proof variants: 80-75- 60-40- 20-100- 90-100 90 Ambient Temperature C 75 T6 T5 T4 75 90 130-25 0 20 40 60 80 100 120 130 Fluid Temperature C Note: Consult factory to determine the functional temperature limit of your transmitter variant. Temperature class ratings do not correspond with the continuous duty area for the electronics within the transmitter. A complete description of your transmitter may be found on the Max Machinery web site (www.maxmachinery.com). Individual specification sheets and product family manuals are also available for viewing or downloading. Max Machinery, Inc. 210 Series User Manual Copyright 2012 Rev. #0312 23
