The explosionproof MASFLO-OVAL Ⅱ FHC series is the hydrogen explosionproof model of general-purpose mass flowmeter FHA series. Likewise, the FHD series consists of mass flow controllers FHB with hydrogen explosionproof control valve. Explosionproof mass flow controller for gas service can be configured by combining these two instruments. The explosionproof MASFLO-OVAL Ⅱ is most suited for various gas
supply systems, gas mixing processes, and measurement/control of gases used in hazardous areas of a pilot plant, semiconductor manufacturing process, and laboratories.
1. JIS explosionproof construction "d3aG4" applicable to H2 gas.
2. Wide flow range: 5NCCM (mL/min [normal]) to 500NLM (L/min [normal]) (Up to 100NLM as a controller)
3. Optimal full scale adjustment available with laminar flow eelment.
4. Applicable to a wide pressure range from vacuum up to 39.2MPa
5. Capable of measuring most gases except for highly corrosive gases.
6. Fast response.
7. The control valve is of normally-closed electromagnetic type to provide fast response and safety.
8. Compatible with a wide variety of applications when combined with the readout unit.
