Compensation issues in gas flow meters
Thread Content
This post was last edited by mlg on 2012-12-17 at 10:46. A orifice flow meter was installed on the gas pipeline; the design condition specified a pressure of 2.0 MPa, while the actual operating pressure is 1.7 MPa. The process team keeps saying that there is a large difference in the instrument readings, which is really frustrating. Dear experts, is compensation possible? If so, how can it be provided? Is there any formula?
Install a pressure sensor on the pipeline and feed the pressure signal into a flow integrator with compensation functionality
Are you blast furnace gas or coke oven gas? What is the traffic range? What is the straight pipe length? The accuracy of thermal and pressure compensation will definitely be high. Provide specific parameters so that our company’s technical team can offer some advice.
