Overview
Oval gear flowmeter is a volumetric meter for continuous or intermittent measurement and control of liquid flow in a pipeline. It has many advantages, such as large range, high accuracy, small pressure loss, strong viscosity adaptability, measurement of high temperature and high viscosity liquid, convenient calibration, installation suggestion and so on. It is suitable for flow measurement in petroleum, chemical, chemical fiber, transportation, commerce, food, medicine and health departments.

LC-13 Oval Gear Flowmeter
LC-13 oval gear flow transmitter consists of the body and transmitter, by which liquid flow in the pipeline can be converted into flow pulse signal or analog signal output. It can be matched with the display instrument or other secondary instruments and systems of our factory. It is used for remote metering display, automatic control and regulation and recording.
Technical performances
Suitable for all cast iron, cast steel, stainless steel flow transmitters.
Transmitter: MF(4-20mA)，GF(photoelectric pulse)
Allowable working voltage: DC12V, DC24V
Pipeline connection flange: JB/T79~82—1994
Transmission distance: 0-1000M
Electrical performance accuracy: ±1 pulse
Ambient temperature: -10~+60℃
