The Gas Metering Control Unit GMCU-30/42 is designed for stationary gas engines as a main component of a full authority engine management system. It can be used for gas ow control or lambda control. By receiving a ow setpoint signal via CAN it adjusts the gas ow to the gas mixer. It can be used for all gas qualities from LPG and natural gas to land ll and wood gas.
A high accuracy throttle valve actuator device and precise calibration of the gas metering unit provides outstanding ow control within a wide inlet pressure range. This allows the use of the valve at higher pressure conditions with increased mass ow and eliminates the need for a zero pressure regulator.
