Page 4: How It Works
How It Works Max H-Series Precision Flow Meters are positive displacement helical meters that are able to operate over a wide range of flow rates and fluid viscosities. High accuracy measurement is achieved through precision machined helical rotors that move proportional to the flow. High resolution outputs are produced by measuring the direction and speed of the helical rotors and converting the signals to analog or frequency outputs. -
Page 5: Installation Mechanical
Installation - Mechanical Your Max Flow Meter has been configured at the factory to be used out of the box based on your submitted application data. Plumb it, wire it, and use it. The following section will provide instructions on how to properly plumb your Max Flow Meter in the liquid lines of your application. - Page 6 ANSI Flanges: Using H-Series meters at pressures greater than 500 psi (35 bar) requires flanges. See the specifications and bolt torque table below. Max bolt kits are available for flange installations. Always use process fluid compatible lubricant on the o-ring to attach the fitting to the meter.
- Page 7 Purging lines with compressed air or steam are typical cleaning methods. Valve #1 Do not use compressed air or steam on the Max flow meter, damage will occur. RADIATE HEAT HERE High Temperatures: Orient your meter so the transmitter is to the side or below to minimize heat transfer by convection from the flow meter to the transmitter.

Page 10: Electrical Quick Start
Start-up Instructions - Adjustments to Factory Settings Required If you need to make adjustments to your Max Flow Meter prior to use, you will need to purchase and use the Max Machinery Interface Software Kit (SFT-KIT-001). This will allow you to change the flow meter output signal frequency or analog range to meet your application equipment needs. - Page 11 Electrical Installation Instructions - 5-pin Turck Connectors Applies only to transmitters with 5-pin, M12 style connectors. For hazardous location transmitters with 1/2 inch conduit connections, please refer to the EXInstall sheet. Frequency Output Transmitters (PN ending N/-) Turck® Connector Mating Cable Pin # Wire Color Label...
- Page 12 Electrical - Operating Information Max Flow Meters require a fully isolated power supply to operate. Refer to the Max Machinery Interface Software Kit Manual for instructions on how to change the flow meter output signal frequency or analog range to meet your application’s equipment needs.
- Page 13 LED Rotation/Output Indicators All Max transmitters incorporate an alternating red/green or blue/green LED to indicate magnet rotation in the meter. The color changes each 1/2 revolution of the meter. Additionally, when no flow signal is present, a rapidly flashing red...

Page 14: Field Compensation Of Transmitter
An alternating blue/green LED indicates that the circuit is detecting a magnet and provides an output signal. A steady or flashing red LED indicates a problem with the transmitter PCA. Contact Max Machinery to have your flow meter refurbished. - Page 15 The flow meter being compensated must not be used for system flow rate feedback control during this process. The transmitter output is disabled during the compensation routine. If you are unable to run a stable flow in the field, send your meter in to Max Machinery for calibration. The compensation routine is as follows: 1.

Page 16: Led Functions
5 revolutions at the stated flow rates. If compensation fails, restart the compensation process. When using the Interface Software Kit, follow instructions provided to correct errors prior to attempting compensation again. If problems persist, contact Max Machinery at 707-433-2662 or at www.maxmachinery.com. -
