LC-40 cast steel elliptical gear flowmeter

Description :

　　LC cast steel elliptical gear flowmeter

　　This product has high measurement accuracy, is less affected by liquid viscosity, and does not require a straight pipe section to be installed in front of the meter. It is widely used for cumulative flow measurement of oils and high viscosity media in petroleum, chemical, pharmaceutical and health industries.

　　1、 Main features:

　　The caliber ranges from 10 to 150mm;

　　There are multiple options for shell materials to choose from: aluminum, stainless steel, and medium to high pressure stainless steel PPS、 Bronze, etc;

　　There are various bearing materials to choose from: ceramic, bronze, Hastelloy, carbide PPS、 Stainless steel, etc;

　　◆ Material of shaft: 316 stainless steel;

　　The materials for O-rings include VITON, fluororubber, stainless steel, and Teflon for selection;

　　The range ratio is 10:1, and the maximum can reach 50:1;

　　The accuracy is two types: ± 1% and ± 0.5%, with a repeatability of ± 0.03%;

　　During installation, the straight pipe section requires 5D+3D and a filter needs to be installed;

　　The viscosity can reach 1000 000CP;

　　The pressure level can reach 551 bar;

　　The temperature resistance level can reach -10~60 ℃.

　　3、 Installation:

　　1. A filter should be installed in front of the elliptical gear flowmeter, and the arrows on both casings should point in the same direction as the flow.

　　When the measured liquid contains gas, a gas separator should be installed in front of the elliptical gear flowmeter.

　　3. Regardless of whether the pipeline is installed vertically or horizontally, the elliptical gear shaft in the elliptical gear flowmeter is installed in a horizontal position. (The dial should be perpendicular to the ground)

　　4. When the elliptical gear flowmeter is installed correctly, if it is difficult to see the reading clearly, the counter can be turned 180 ° or 90 °.

　　Before installing the elliptical gear flowmeter, use a bamboo stick to push the gear several times from the outlet. If it doesn't move, soak it in gasoline (to avoid sediment accumulation after factory calibration)

　　6. The throttle valve should be installed at the inlet of the elliptical gear flowmeter, and the switch valve should be installed at the outlet. When opening and closing each valve, it should be started slowly and not quickly opened or closed.

　　7. It is strictly prohibited to use sweeping steam to pass through the elliptical gear flowmeter.

　　8. In the continuous use department, the elliptical gear flowmeter needs to be equipped with a bypass pipeline.
