Gear flow meter working principle

Gear flow transmitter is a type of positive displacement flow transmitter. It is a highprecision transmitter for measuring volume flow.

With the flow of the medium, the gears mesh and rotate. Under the action of the fluid flow, a pressure difference is formed at both ends of the instrument inlet and outlet. There is no need for power supply. A pair of gears rotate freely. The cavity between the gears is filled with liquid. Discharge and measure the number of revolutions of the gear to know the flow of liquid and liquid flowing through the instrument.

Figure 1 Schematic diagram of fluid flow

The rotation speed of the round gear transmitter is detected by the sensor coil in the signal amplifier mounted on the watch case. The signal amplifier is not in contact with the measured medium. When the transmitter gear cuts the magnetic field lines generated by the permanent magnet in the housing, it will cause the magnetic flux in the sensing coil to change.

The sensing coil sends the detected magnetic flux periodic change signal to the preamplifier, amplifies and reshapes the signal, generates a pulse signal proportional to the flow rate, and sends it to the unit conversion and flow integration circuit to obtain and display the cumulative flow value. At the same time, the pulse signal is sent to the frequency current conversion circuit, which converts the pulse signal into an analog current quantity, and then indicates the instantaneous flow value.

The round gear transmitter has high machining accuracy and precise installation. The rotation of the gear is scanned non-contact, and each tooth generates a pulse with very high resolution. Cylindrical gear transmitters can measure very small flow and quantify small volume of liquid.

FAQ

What is a gear meter?

Gear flow meters are a type of positive displacement flow meters. It is used for precise continuous or discontinuous measurement of the flow or instantaneous flow of liquid in the pipeline. It is especially suitable for the flow measurement of heavy oil, polyvinyl alcohol, resin and other high viscosity media.

What is oval gear flow meter?

Oval gear flow meter (also known as displacement flowmeter, gear flowmeter) is a type of positive displacement flowmeter. It is a category with higher accuracy in flow meters. It uses mechanical measuring elements to continuously divide the fluid into individual known volume parts. The total flow volume is measured according to the number of times that the metering chamber is filled and discharged with this volume of fluid successively and repeatedly.
The oval gear flowmeter can be made of different materials (cast iron, cast steel, 304 stainless steel, 316 stainless steel), and is suitable for flow measurement in the chemical, petroleum, pharmaceutical, electric power, metallurgy and food industries.
