MASFLO-OVAL II / THERMAL MASS FLOWMETER/CONTROLLER

Format:FHA, FHB

Liquid

Gas

Steam

The MASFLO-OVAL Ⅱ FHA/FHB series measures and controls the flow rate of gas based on mass. The FHA series consists of highly accurate and compact mass flowmeters (MFM) for gas measurement. The FHB series consists of mass flow controllers (MFC) composed of an electromagnetic control valve integrated with the FHA flowmeter. Simple flow measurement/control system can be configured by combining the FHA/FHB with
the readout unit (ROU). The ROU is equipped with display and setting device. The MASFLO-OVAL Ⅱ is most suited for various gas supply systems, gas mixing processes, and measurement/ control of gases used in the pilot plant, semiconductor manufacturing process, and laboratories.
