Cast Iron Oval Gear Flow Meter DN80(light) LC-QA80.2/Z DN80(heavy)LC-QA80II.2/Z Flux 8-40m³/h for Oil Tanker Loading Unloading

Application & Working Purpose of Oval Gear Flow Meter

This oval gear flow meter is a high-precision volumetric metering device designed for liquid medium flow measurement. It can be mounted on pipelines conveying crude oil, gasoline, diesel, lubricating oil, fuel oil and various low-viscosity chemical solvents. Widely used for bulk oil trade settlement, factory production liquid blending and quantitative filling operations, it is a core measuring component for oil depots, tank truck loading stations and large oil storage facilities. Installed on oil inlet and outlet pipelines, it records real-time flow data accurately to support weight verification, transaction accounting and production data statistics, ensuring reliable and traceable liquid metering results.

Core Measuring Principle & Advantages of Elliptical Gear Flow Meter

Its core function lies in high-precision volumetric measurement, which can accurately record and display the cumulative liquid volume passing through pipelines within a certain period, with readable metering units including liters and cubic meters for oil and other liquids. This mechanical elliptical gear flow meter fits high-viscosity liquid measurement perfectly. Driven by interlocked internal elliptical gears, it retains outstanding measurement precision when handling thick, poor-flow fluids, and is barely disturbed by turbulent flow and other unstable fluid states.

High Precision, Stable Performance & Low Maintenance Oil Measuring Device

• Mechanical gear meshing transmission delivers high-precision volumetric fluid measurement. It is especially applicable to scenarios involving trade settlement and precise production blending, with measurement errors controlled within an extremely low range.

• Unlike velocity flow meters including turbine and electromagnetic flowmeters, this elliptical gear flow meter does not rely on fluid velocity distribution or turbulent flow states. It can sustain stable metering performance even when slight turbulence exists inside pipelines, and works well for sites lacking adequate straight pipe sections.

• The built-in gear structure delivers outstanding sealing performance when measuring viscous media including heavy oil, lubricating oil, adhesives and resin. Higher liquid viscosity brings less internal leakage and higher measurement precision — strengths unmatched by most other types of flow meters.

• The mechanical counter mounted on the top needs no external power supply to accumulate flow readings. With a simple, solid structure and strong anti-interference capability, it perfectly fits outdoor, explosion-proof and power-free working environments.
