Before You Install Thank you for choosing to install a Max Machinery precision flow meter. To ensure the best experience please take a moment to read through this manual prior to installation. When you purchased this meter a flow 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.
Meter General Description The G-Series flow metering systems are the combination of a high pressure gear meter and a high resolution, microprocessor based transmitter. While gear meters are traditionally based on a design similar to a conventional hydraulic pump, the G Series of flow meters has been engineered to increase signal resolution, prevent internal cavitation and greatly reduce the pressure drop required to move fluid through the gears.
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.

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: Install the meter on its side. DO: Be very careful to keep parts clean during installation or teardown.
Installation Prior to installing the flow meter remove the storage caps from the ports and look carefully into each port of the meter. Ensure that no dirt or foreign particles have gotten into the ports of the meter. Make sure that adequate filtration exists upstream of the flow meter and that no contaminants exist in the line between the filter and flow meter. It is recommended that the flow meter be connected to the circuit by means of unions close to the flow meter to allow easy removal.

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.
Electrical Installation - Wiring Wiring FREQUENCY The electrical connector versions are pre-wired inside the transmitter and ready to accept a mating cable (available from the factory).
