The GPRO QM40 Mechanical Fuel Meter provides precision fuel measurements for more accurate readings for fleet operations, heavy equipment, and agricultural applications. It features a magnetic drive mechanism that is nearly frictionless; less friction results in more flow, capable of handling flow rates up to 40 GPM. The QM40 is equipped with both NPT and Flange connections which allows it to be installed on all threaded pump outlets or modular GPI products.
