Introduction

Oval gear flow meter is one of positive displacement flow meter and is mainly composed of meter shell, oval gear rotor and converter. It is an instrument used for continuous or discontinuous metering and control of liquids in the pipeline. It has advantages of large metering range, excellent accuracy, small pressure loss and high viscosity adaptability.

It has good performance on measuring high-temperature and high-viscosity liquids. It is applicable to the calibration and metering of crude oil, chemical, chemical fiber, traffic, commerce, food, medicine and health, scientific research and military etc.

Advantages

QTLC Positive Displacement Oval Gear Flow Meter technology provides a number of advantages as belows:

High Accuracy of Reading, 0.5% standard and optional 0.2% of reading.
Excellent Repeatability
Minimal Maintenance
Suitable for numerous fluids including Water, oil and High Viscous Fluids
Ease of Installation, No Flow conditioning needed
Good Turn Down Ratios
Accuracy unaffected by changes in Viscosity
No power required with pulse or mechanical register
Industrial Heavy Duty Robust Design
Output options including: Pulse, 4-20mA, RS485; Intrinsically Safe & Explosion Proof

Application

It is widely used in liquid flow control in various industrial fields and is suitable for various types of liquid measurement, such as crude oil,diesel, Gasoline, etc. It has the characteristics of large range, high precision,convenient use and maintenance.
