LC series elliptical gear flowmeterDetailed product description：

1、 Overview of flow meters

The LC series elliptical gear flowmeter is a direct reading cumulative instrument, which is a volumetric flowmeter that measures the total flow rate of liquid flowing through pipelines. Mainly used for measuring the cumulative flow rate of petroleum products, it can also be used for measuring other chemical solutions. It can be widely used for flow measurement in sectors such as petroleum, chemical, pharmaceutical, and health.

2、 Working principle of flowmeter

This flowmeter is a direct reading cumulative fluid flowmeter, consisting of a measuring chamber equipped with a pair of elliptical gear rotors, a sealed coupling (small caliber flowmeters use highly sensitive magnetic couplings), and a counting mechanism. Under the action of the liquid pressure difference at the inlet and outlet of the instrument measurement room, a pair of elliptical gears continuously rotate on the shaft and discharge the liquid. By measuring the number of revolutions of the elliptical gears, the total amount of liquid flowing through the instrument can be determined.

3、 Functional characteristics of flow meters

High precision, less affected by liquid viscosity.
No straight pipe section needs to be installed in front of the meter.
Good reliability, long lifespan, wide range, and low pressure loss.
The measurement is basically unaffected by temperature and pressure changes, and it is easy to install.
