1.Best choice for high pressure hydrogen gas measurement. 70MPa class.
2.Premium materials and structure applied to make it embrittlement-resistant for hygrogen. Wide working temperature range: -50℃ to +85℃
3.High accuracy (±0.5%rate Range 20:1) and low pressure loss. Small sensing unit well responds to tiny flow.
4.Optimized design for HRS (hydrogen refueling stations) conforms to Japanese high pressure gas safety rules and explosion-proof construction.
5.Flow meter for high pressure hydrogen. The volume and weight of the flowmeter has been reduced to 1/3 or less when compared to our conventional models.
6.Communication system supports RS485 (Modbus ASCII) and Bluetooth compatible.
