Selection of flow meters for hydrogen pipelines
Thread Content
Volumetric flow meter: Medium – hydrogen; DN50 size, operating pressure of 0.3 MPa (design pressure of 1.0 MPa); flow rate of 320 cubic meters per hour. Connection type is flange. Instantaneous and cumulative display on-site is required, with high precision being preferred. Another model: DN100 size, operating pressure of 0.3 MPa (design pressure of 1.0 MPa); flow rate of 180 cubic meters per hour. Connection type is flange; instantaneous and cumulative display on-site is required, with high precision being preferred. Yet another model: DN50 size, pressure of 8 KPa, flow rate of 80 cubic meters per hour; connection type is flange. Instantaneous and cumulative display on-site is required, with high precision being preferred. The client has specified the Rosemount brand; currently, a choice is being made between a compact orifice flow meter and an vortex flow meter. Could experts please provide some advice on the advantages and disadvantages of each option?
