common problem
Q1: Can the digital gas flowmeter have perfect accuracy?
A1: In an ideal situation, the flow reading of the process instrument will be completely correct without any type of deviation. Unfortunately, this is not the case, and inherent errors in measurements must always be identified, considered, and minimized as much as possible.
Q2: Does the digital gas flowmeter need to be calibrated?
A2: In the production process of Flowmeters, several steps are required, such as coil winding, lining processing, and electrode assembly. This series of operations will cause a certain degree of error and dispersion in the equipment, so a calibration process is needed to correct the accuracy.
Q3: Does the digital gas flowmeter have temperature compensation function?
A3: Yes. As long as these temperature changes are within the temperature compensation range, the output reading will compensate for the temperature changes.
Tip: What factors can affect the measurement accuracy of an electromagnetic flowmeter?
1. The liquid to be tested contains bubbles.
2. The liquid to be tested is not full in the pipeline.
3. Short circuit effect of conductive deposits.
4. Crystallization occurs in liquids.
5. The conductivity of the liquid exceeds the allowable range.
6. Space electromagnetic interference.
7. Asymmetric flow rate of the fluid to be tested.
8. The vibration at the installation site affects the accuracy of the Flowmeter.
