What methods can be used to reduce the error of the gas flowmeter

Each gas flow meter has its own accuracy, but this accuracy usually refers to the accuracy measurement made by the manufacturer in its own environment, and the environment we are in in actual use may be very different, so Will reduce the accuracy. Below we will specifically explain the reasons and solutions for the decreased accuracy of gas flow meters?

For positive displacement flowmeters under actual working conditions, the additional error caused is usually due to the influence of the temperature and pressure of the fluid medium on the volume of the metering chamber. When the material of the chamber is known, the volume change can be calculated. The flow meter displays the reading of the meter to be corrected. The actual viscosity of the fluid may also have an impact on the meter readings, which should be considered according to the meter's instructions. The length of the straight pipe section generally does not affect its accuracy, which is a prominent advantage of gas flow meters. The content displayed by this kind of flowmeter is the volume flow of the measured medium in operation. What we need to get is the volume flow of the measured medium under standard conditions, and the density of the fluid must be compensated. It is understood that the current new gas flow meters all use intelligent technology, which can automatically compensate for density.
