LC oval gear flow meter

Detail

Overview

LC series elliptical gear Flowmeter is a direct reading accumulative meter. It is a volumetric Flowmeter that measures the summation of liquid flow through the pipeline. Can be widely used in petroleum, chemical, medical and health departments of the flow measurement.

Operational principle

Under the effect of the liquid pressure difference between the inlet and outlet of the instrument measuring chamber, a pair of elliptical gears rotate continuously and discharge the liquid on the shaft.

LC oval gear flow meter

1. Precision grade: 0.5 class、 0.2 class (usually in - 10 ℃ ~ + 60 ℃)

2. suitable for medium temperature: - 20 ℃ ~ + 80 ℃, in cases of up to 200 ℃ heat

3.Explosion-proof grade:ExiaIICT6

Instrument characteristics

High accuracy, wide flow range and good repeatability;
The spiral rotor has uniform rotation, small vibration and long life;
It is not sensitive to the change of the viscosity of the tested liquid, especially suitable for the measurement of the liquid with higher viscosity;
Simple structure, small size and light weight;
Easy to install, no straight pipe segments need to be installed before the table.
