Overview
The LC elliptical gear flowmeter is a volumetric measuring instrument mainly composed of a measuring housing, an elliptical gear rotor, and transmission components. Instruments used for continuous or intermittent measurement and control of liquid flow in pipelines. It has the advantages of large range, excellent accuracy, low pressure loss, strong viscosity adaptability, ability to measure high-temperature and high viscosity liquids, convenient calibration, and easy installation. Suitable for measuring flow in crude oil, chemical, synthetic fiber, transportation, commerce, food, medical and health, scientific research, and military industries. The elliptical gear flowmeter can indicate accumulated flow, instantaneous flow, single flow, etc. on site, and output pulse signals, 4-20mA
Product Details
1：LC elliptical gear flowmeter
Functional Block Diagram 
2: Characteristics of LC elliptical gear flowmeter
All parts of the flowmeter are precision machined on the surface, with no casting surface, and the surface is smooth and beautiful.
The flowmeter is designed to be disassembled and reassembled on site without the need for professional personnel, and the original measurement accuracy remains unchanged after reassembly.
The flowmeter adopts waterproof design.
The flowmeter can display cumulative flow, instantaneous flow, single flow, etc. on site.
Flow meter execution standard: NIST (National Institute of Standards and Technology)
