LL Oval Gear Flow Meter
LL Oval Gear Flow Meter
The oval gear flow meter is a high-precision positive displacement meter with an accuracy of ±0.2% to ±0.5% (special up to ±0.1%), unaffected by flow conditions and Reynolds number. It is widely used for precise metering of oil products and chemical solutions in petroleum, chemical, and commercial trade.
- High-precision positive displacement measurement, basic error ±0.2% to ±0.5% (special ±0.1%)
- Unaffected by flow conditions and Reynolds number
- Wide range ratio, typically 5:1 to 10:1
- Totalizer with drum counter, no external power required
- Can be equipped with transmitter and intelligent controller for remote transmission and control
- Simple structure, long life, easy installation and use
Overview
Product Overview
The oval gear flow meter is a high-precision metering instrument for continuous or intermittent measurement of liquid flow in pipelines. It features high accuracy, good reliability, light weight, long service life, and easy installation and use. It is a typical product of positive displacement flowmeters. Widely used in petroleum, chemical, electric power, metallurgy, transportation, food processing, pharmaceutical, national defense, and commercial trade for precise metering of fluids such as petroleum and petroleum products, chemical solutions, etc.
Structure Composition
It mainly consists of a metering chamber, a sealed coupling, and a counter. It can indicate cumulative and instantaneous flow locally. With a transmitter and intelligent controller, remote measurement and control can be achieved.
