HCH2 Hydrogen Flowmeter for mass flow rates of 0.1…541 g/s

This state-of-the-art, superb quality flow meter can measure flow rates as low as 0.1g/s @10 bar up to 541g/s @1000 bar with a very low pressure drop. For flow rates below 0.1 g/s, please see the HOH2 Hydrogen Flowmeter, which is compatible with flow rates between 0.008g/s and 108g/s.

An internal flow computer uses an algorithm based on differential pressure between 2 points in the flow meter body, static pressure and temperature to calculate the flow rate in g/s or kg/hr.

The built-in display shows this calculated flow rate, static pressure (bar) or temperature (ºC). The included Modbus output also makes flow, pressure and temperature values available externally, with the flow rate also available via a 4...20mA output.

In tank loading applications, the pressure drop across HCH2 flow meters is significantly less than that of other technologies by up to 20 to 30 times. This creates a much lower temperature rise in the hydrogen in these circumstances, meaning loading can take longer at higher flow rates, drastically cutting the loading time and increasing throughput.
