    Q1: Can a digital gas flow meter have perfect accuracy?
    A1: In an ideal world, the flow readings from your process meter would be exactly correct, without any type of deviation. Unfortunately, this is not the case, and the errors inherent in measurement must always be identified, accounted for, and minimized as much as possible.

    Q2: Does a digital gas flow meter need to be calibrated?
    A2: During the production of a flow meter, several steps are required such as coil winding, lining processing, and electrode assembly. This series of operations can cause a certain amount of error and dispersion in the device, so a calibration process is required to correct the accuracy.

    Q3: Do gas mass flow meters have temperature and pressure compensation?
    A3: Our MF4000/5000/5700 series are all without temperature/pressure compensation. As long as the gas is under working pressure & temperature ranges, the accuracy will be as stated.

    Tips: What affects magnetic flow meter measurement accuracy?

    1. liquid to be tested contains bubbles.
    2. The liquid to be measured is non-full in the pipe.
    3. Short circuit effect of conductive sediments.
    4. The liquid generates crystallization.
    5. Liquid conductivity exceeds the allowable range.
    6. Spatial electromagnetic disturbance.
    7. Unsymmetrical flow of the fluid to be measured.
    8. Vibration of the installation site affects the accuracy of flow meter.

    The digital gas flow meter works very well
    I have been using the digital gas flow meter for a few months now and this meter has been a great addition to my industrial setup and I must say I am very pleased with its performance. The easy to read digital display makes tracking the flow accurately effortless.
