MGF420 Thermal Mass Flow Meter

Compressed Air Flow Meter

The MGF-420 Series flow meter is a simple and economical solution for the measurement of compressed air and process gases in smaller diameter pipes. Through precise measurement of the cooling effect a direct mass flow reading can be calculated therefore additional temperature and pressure sensors are not required.

The MGF-420 is supplied with its own stainless steel measuring section pipework. This feature provides a much higher degree of accuracy as factory calibration of the sensor is carried out with it mounted in its own measuring section. The MGF-420 not only calculates and display mass flow rate and total but also provides signal outputs to interface with other process instrumentation. A 4-20mA output linear to instantaneous mass flow rate and a scaled pulse for flow total are available as standard.

Due to its compact design and flexibility the MGF-420 can be used to monitor a wide range of compressed air systems from the compressor itself to the smallest compressed air tool. The MGF-420 is designed for pipeline installations from 1/2” to 2”. For larger installations, 2” to 12”, we can offer the MGF400 (see separate data sheet)

The MGF 420 is not only suitable for compressed air measurement but can also handle such gases as nitrogen, oxygen and CO2 Installation of MGF-420 can be carried out easily and quickly. Should the sensor require removal for calibration or cleaning purposes this can be done without removing the complete measuring section from the pipeline.
