    Oval flow meter detail two

    Oval flow meter with exquisite workmanship

    • Multi-process construction, strong pressure resistance.
    • Spray paint of cast iron makes the service life of flowmeter longer.


    Oval gear flow meter consists of two oval gears that rotate inside a housing. The flow of liquid causes the gears to rotate, and the rotation is proportional to the flow rate. Oval flow meter is widely used in chemical industry, medical industry and metallurgical industry.

    Q1: Can a oval flow meter have perfect accuracy?
    A1:Β 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 oval 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 oval flow meters have temperature compensation?
    A3:Β Yes. As long as these temperature variations are within the temperature compensation range, the output reading compensates for the temperature variations.

    Tips: How does oval flow meter work?

    Oval gear flow meters are a type of positive displacement flow meter that operates based on the principle of the flow-induced rotation of oval gears. The basic components of an oval gear flow meter include two oval-shaped gears that are placed in a chamber. The chamber has an inlet and an outlet for the fluid flow, and the gears are connected to a shaft that rotates as the fluid passes through the meter.

    As the fluid flows through the meter, it enters the chamber and pushes the gears in a rotation. The rotation of the gears is proportional to the volume of fluid that has passed through the meter. The rotation of the gears is detected by sensors that are placed outside the chamber, and the output signal is sent to a display or a data acquisition system.
