Product Description
Gear flow transmitter belongs to a kind of volumetric flow transmitter and can be used for measuring 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 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 key questions which need to be answered before selecting an oval gear flow meter are:
1.what's the fluid?
2.what's flow range? and pipe size?
3.what's working pressure?
4.what's working temperature?
5.do you need display or not?
