The LC series Oval Gear Flowmeter, optional intelligent electronic counter, can directly read the total accumulation of flow on the flowmeter, instantaneous flow. After external power supply, pulse and current signal can be output, HART communication and RS485 communication output can also be realized; An optional mechanical counter can directly display the cumulative flow of liquid flowing through the pipe. For different liquids (acid, alkali, salt, organic solution, etc.) flow meters can be selected from different materials (cast iron, cast steel, aluminum alloy, stainless steel, etc.).
The LC series Oval Gear Flowmeter is suitable for flow measurement in petroleum, chemical, chemical fiber, transportation, commerce, food, medicine and other industrial sectors.
The application scope is very wide.
The Oval Gear Flowmeter consists of a flow transmitter and a counting mechanism. The main part of the transmitter is composed of a measuring chamber equipped with a pair of elliptical gear rotors and a sealing coupling. The counting mechanism includes decelerating mechanism, precision adjusting mechanism, counter and electric pulse transmitter and other components.
