The Micro Flow Meter we supply is a gear flow meter.

Gear flow transmitter belongs to volumetric flowmeter and measure volume and flow precisely. The flowing medium makes the gear engage and rotate.

Under the flowing effect of fluid, pressure difference is formed between the inlet and outlet of instrument. One pair of gears can rotate freely without the need of power supply. The empty cavity between gears is filled with liquid, which is discharged through rotation.

The liquid flowing through instrument and liquid flow can be known through measuring the number of revolutions of gear.

Micro Flow Meter working principle

Extended reading: Cylinder Gear flow meter for micro flow measurement.

The rotation speed of the transmitter is detected by the sensing coil inside the signal amplifier on the case.

The signal amplifier cannot touch the measured medium. Due to the cutting of the transmitter gear, the magnetic field lines generated inside the permanent magnet inside the housing will cause the magnetic flux inside the induction coil to change.

The sensing coil sends the signal of flux change cycle detected to the pre-amplifier so as to amplify and shape the signal.

The impulse signal which is in direct ratio with flow velocity will be sent to the unit conversion and flow integration circuit. To obtain and display the accumulative flow valve.

At the same time, it will also send the impulse signal to frequency current conversion circuit. To convert the impulse signal to simulation amperage so as to display the instantaneous flow value.
The transmitter has high processing precision and can be installed precisely.

The gear rotation undergoes non-contact scanning. One impulse is generated by one gear with very high resolution. The column gear transmission can measure the liquid with very small flow and small quantitative volume.

The difference between a flow meter and a flow sensor. The main points are as follows:

  1. It can be said that the flow sensor is part of the flow meter. The sensors include flow sensors and flow meters, which belong to a broad category.

Specifically: the flow sensor can measure the specific flow value. For example, a water meter, which is actually a flow meter. But there is a flow sensor in the flow meter. A flow meter is a combination of a flow sensor and a meter display. When the water flow passes through the flow sensor, the flow sensor transmits the record to the meter head. The header displays it in front of the user according to the data.

  1. The flowmeter generally refers to those sensors that can be read directly, and specifically refers to those measuring elements that can convert the measured flow value into an electrical signal for processing by the processor.
  2. The flow meter is used for measurement, and it gives the quantity of medium flowing through per unit time (flow rate such as ton/hour). Flow sensors determine the fluid flow state, and some (but not all) of the sensor signals can be processed to generate a flow signal. If this sensor is integrated with other components, it is a flowmeter.
  3. According to the professional method, the functional flow meter is for measurement. It mainly measures the flow, and the accuracy is the main parameter of the flowmeter. Flow sensor is signal output, electrical signal, pulse signal. Also known as analog output. is for flow control.
