Gasoline DN25 Oval Gear Flow Meter Positive Displacement

Gasoline DN25 Oval Gear Flow Meter Positive Displacement

Product Description

Oval gear flow meters (also known as displacement flow meters, gear flow meters) are a type of positive displacement flow meters, and they are the most accurate type of flow meters. It uses a mechanical measuring element to continuously divide the fluid into a single known volume part, and measures the total flow volume according to the number of times that the metering chamber is filled and discharged with the volume part of the fluid successively and repeatedly. The oval gear flowmeter can be made of different materials (cast iron, cast steel, 304 stainless steel, 316 stainless steel), and is suitable for flow measurement in the chemical, petroleum, pharmaceutical, electric power, metallurgy and food industries.

Features
The flow measurement has nothing to do with the flow state of the fluid. This is because the oval gear flowmeter relies on the pressure head of the measured medium to push the oval gear to rotate for measurement.

The greater the viscosity of the medium, the smaller the leakage from the gear and the metering gap. Therefore, the larger the sticky skin of the nuclear test medium, the smaller the leakage error, and the more beneficial to the measurement.

The elliptical gear flowmeter has high measurement accuracy and is suitable for the measurement of the flow of high-viscosity media, but not for fluids containing solid particles (solid particles will jam the gear and make it impossible to measure the flow). If the measured liquid medium contains gas, it will also cause measurement errors.
