Features of Micro Flow Meter
Quantitative control of micro liquid flow & flow monitoring.
The standard minimum flow rate of the micro flowmeter is 0.5ml/min.
The standard accuracy of the micro flowmeter is 0.5%. The cutting accuracy of the CNC machining center is 0.001mm.
For high viscosity media, such as glue, the accuracy can reach 0.2%.
The maximum range ratio of the standard product is 1:200, and the minimum range ratio is 1:100
The new M2.1 is the latest research and development. The flow range is 1~800ml/min, and the turndown ratio reaches 1~800.
To meet more working conditions, it is more suitable for test bench working conditions.
Two materials of stainless steel and aluminum alloy are available.

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.

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.
