　　Large caliber LC-80 elliptical gear flowmeter

　　The LC elliptical gear flowmeter is one of the typical volumetric flowmeters used to measure the flow rate of liquid filled in a pipeline under a certain pressure. It has the characteristics of simple structure, reliable use, high accuracy, no special requirements for the flow field inside the inlet and outlet pipelines, and a wide range of viscosity and flow rate of the measured medium. Therefore, it is widely used for liquid flow detection in industries and commercial sectors such as petroleum, chemical, pharmaceutical, transportation, and food. The LC series elliptical gear flowmeter is particularly suitable for measuring oil and fuel.

　　2、 Product Usage

　　LC-A type cast iron elliptical gear flowmeter is widely used for measuring various oil products and non corrosive liquid media of cast iron materials.

　　LC-E type cast steel elliptical gear flowmeter, used for measuring high-pressure and low corrosive media.

　　LC-Q type cast iron elliptical gear flowmeter, with an aluminum alloy rotor, is suitable for measuring low viscosity, low corrosion (such as gasoline, etc.) liquid media.

　　LC-B and C-type stainless steel elliptical gear flow meters are widely used for measuring highly corrosive liquid media such as acids, alkalis, salts, and organic compounds.

　　LC-L aluminum alloy elliptical gear flowmeter is a lightweight elliptical gear flowmeter widely used for measuring low corrosive liquid media, such as water and other liquid media.

　　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.
