Techniquip Series MGF-420 flowmeters for compressed air and gases

Click2Contact

The MFG-420 flowmeter is suitable for the accurate mass flow measurement of compressed air and gases with rate/total display and 4-20 mA or pulse outputs. Display engineering units and gas type software are selectable.

The product operates using the calorimetric measuring principle. This technology uses a heated sensor which is cooled by the gas flow as it passes and the degree of cooling is dependent upon the mass flow rate of the flow medium. 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 flowmeter not only calculates and display mass flow rate and total, but also provides signal outputs to interface with other process instrumentation. It features a 4-20 mA output linear to instantaneous mass flow rate and a scaled pulse for flow total. The product is also supplied with its own stainless steel measuring section pipework, which is said to provide a higher degree of accuracy as factory calibration of the sensor is carried out with it mounted in its own measuring section.

Due to its compact design and flexibility, the product can be used to monitor a wide range of compressed air systems, from the compressor itself to the smallest compressed air tool. Applications may include: compressed air monitoring and flow balancing; leak detection and management; portable compressed air measurement; flow measurement of process gases; flow measurement of nitrogen generators.

The product is designed for pipeline installations from 0.5 to 2″. It is easy to install, with no moving parts and no additional temperature or pressure sensors necessary. There is negligible pressure loss and it can register capacity to 1,999,999,999 m³.
