Why does vortex flowmeter need temperature and pressure compensation
All customers who have used the vortex flowmeter know that the vortex flowmeter can be used to measure liquid and gas, it measures different media configuration accessories are different, we in the compensation instrument * commonly used is temperature compensation and pressure compensation, here we talk about the vortex flowmeter temperature compensation.When measuring steam, the vortex flowmeter will use temperature compensation, because the density of steam varies with the temperature, and the density of steam at different temperatures is straight, related to the quality of the steam, we in order to more accurate measuring steam, on many occasions will add temperature sensors, these are all belong to the requiring higher precision, but there are some occasions, the steam temperature is constant, change is not very big, for these conditions we can consider when selection without temperature compensation, and we just use electronic compensation in the circuit, which can guarantee the accuracy, the vortex street flowmeter can need not take temperature compensation? We cannot generalize, need to decide according to the field condition, the use of steam, which kind of flowmeter to adopt.
