What is the compensation for the steam flow meter? - Focus on microfluidic control technology products and technical solutions service providers

Orifice plate flowmeters need to be compensated for measuring steam, but what kind of compensation method should be chosen for saturated steam flow measurement? Generally, we use pressure compensation, coefficient uncertainty is small, conditional measurement of ordinary steam we have double compensation, intelligent vortex flowmeter to measure steam, our ABG instrument group standard is integrated temperature pressure compensation, double compensation on the direct table Display temperature pressure, instantaneous flow, cumulative flow, plus 4-20MA output if needed.

Vortex flowmeters and orifice flowmeters, generally how to prevent the use of flowmeter performance loopholes to cheat, the inherent characteristics of the flowmeter is no way to change, so we pay attention to the choice of flowmeter can not leak the flowmeter password settings, Because you have a password, you can enter the parameters in the menu settings.

We have this problem in many scenes. Some manufacturers supply steam to other factories. The previous few days are normal. The subsequent meter reading finds that the flow value becomes smaller. If the number is intentionally reduced by 10%, the gas supplier can't find the problem in a short period of time. However, long-term use is also a big loophole. The password needs to be changed after installation, because he can get the initial password when he asks the manufacturer for the sample. All of us need to make a password change if we do the metering after the installation, and there is a 1-2 year return to the factory for a new calibration.
