Before You Install

Thank you for choosing to install a Max Machinery precision ow meter. To ensure the best experience please take a

moment to read through this manual prior to installation.

When you purchased this meter a ow engineer helped determine the best meter for you based on many of the factors

that will be reviewed on the following pages. If you have any questions about installation or operation please don't hesitate to call Max Machinery, Inc. at 707-433-2662

When you are ready to install there will be a few tools you will need:

Meter Installation: The meter and transmitter

A signal cable (available from factory)

The display or signal processing device Indicator Manual

Calibration Certicate

Bypass plumbing supplies

Many Max meters are installed and operate for decades, so having the following information in your records may prove useful. We have provided this outline as a starting point.

Meter General Description

While gear meters are traditionally based on a design similar to a conventional hydraulic pump, the G Series of ow

meters has been engineered to increase signal resolution, prevent internal cavitation and greatly reduce the pressure

drop required to move uid through the gears.

Max ow meters and transmitters are calibrated at the factory as a matched set. This ensures the highest accuracy and allows for quick setup in the eld. For eld installations where the transmitter has not been setup with a meter at the factory, an optional serial interface kit is available to provide full access to all conguration options and parameters.

Solid state sensors are used to detect the position of a driven magnet inside the Max Flow Meter. Changes in position

are tracked by a microprocessor, which generates an output frequency proportional to the ow rate. Advanced signal processing provides both ne angular resolution (0.36 degrees rotation per pulse) and rapid response (output updated

every 1 ms). The G-Series transmitter uses modern sensor technology coupled with advanced signal processing to deliver new levels of performance and reliability.

Flow Meter Features

• Capable of operating at high pressures (425 bar/6000 psi).

• Compatible with a wide range of uid types and viscosities.

• Can operate at high temperatures with a suitable high

temperature transmitter.

• Available in 303 and 316 stainless steel.

Transmitter Features

• High resolution measurement –Analog Output: Congured output ranges to any value within ± 10 Vdc or ± 20 mA.

• Frequency Output: Congured output resolution of 1 to 1000 pulses per revolution.

• Linearization of up to 16 points to fully describe the ow meter’s output curve and achieve the highest system linearity over the meter’s entire operating range.

Transmitter General Description

Max transmitters are designed to work with the entire family of Max Flow Meters to provide extremely precise ow

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.

Compensation Algorithm – Compensates for variations in Hall sensor and ow meter characteristics to provide a stable, undamped output that accurately represents the instantaneous ow 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 ow 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 ow exceeding the buffer setting will result in an output proportional to reverse ow rate. The buffer quantity

can be set from 1% to 100% of a revolution.
