    FAQs

    Q1: Can a metal tube variable area 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 metal tube variable area 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 metal tube variable area flow meters have temperature compensation?
    A3: Yes. As long as these temperature variations are within the temperature compensation range, the output reading compensates for the temperature variations.

    Tips: How does the Metal tube variable area flow meter work?

    The metal tube variable area flow meter float is in the measuring tube. With the change of flow, the float moves upward, and the buoyancy of the float and the gravity of the float reach a balance at a certain position. At this time, the flow annulus area between the float and the orifice plate (or cone tube) remains constant. The area of the annular gap is proportional to the rising height of the float, that is, the rising position of the float in the measuring tube represents the flow rate, and the position of the changing float is transmitted by the internal magnet to the external indicator, so that the indicator can correctly indicate the flow value at this time. . This makes the indicator housing not in direct contact with the measuring tube, so even if limit switches or transmitters are installed, the instrument can be used under high temperature and high pressure working conditions.
