What is the standard of a flowmeter?
However, there are two concepts in our country:1, for the air, nitrogen, oxygen and so on, China's national standard requirements for the situation is 20 degrees Celsius and pressure of 101.325KPa;2, for gas, our country department standard stipulated standard condition is 0 degrees Celsius and the pressure is 101.325KPa.
In brief, the standard condition of a flowmeter is the condition of the flowmeter in the standard state (a standard atmosphere, 20 degrees Celsius). It's neither 25 degrees Celsius, nor 0 degrees celsius.
The standard condition of a flowmeter generally refers to the standard condition of a gas flowmeter. It is stipulated in the world that the temperature is 0 DEG C (273.15 open) and the pressure is 101.325KPa (1 standard atmospheric pressure, 760 mmHg).
