What is Oval Flow meter?

The OVAL flowmeter is a type of volumetric flow instruments, which is a kind of high accurate flowmeters. It utilizes a mechanical measuring element to continuously divide the fluid into a single known volume portion, and measures the total volume of the flow volume. The oval meter can be made of different materials (cast iron, cast steel, 304 stainless steel, 316 stainless steel), and is suitable for flow measurement in chemical, petroleum, pharmaceutical, electric power, metallurgy and food industries.

Where to Use Oval Gear Flow meter ?

The oval gear flowmeter is a type of positive displacement flowmeter for precise continuous or intermittent measurement of the flow or instantaneous flow of liquid in a pipe. It is especially suitable for flow measurement of higher viscosity media such as heavy oil, polyvinyl alcohol and resin; it can also measure flow of diesel, gasoline.etc.
It should measure clean liquid without any solids or gas contained , also the fluids should not be too corrosive.

Why is oval flow meter a good choice for High Viscosity fluids flow measurement?

The flow measurement is independent of the flow state of the fluid. This is because the oval gear flowmeter is metered by the rotation of the oval gear by the indenter of the measured medium. The medium with the higher viscosity, the smaller the leakage amount from the gear and the metering gap, so the larger the stickiness of the nuclear measuring medium, the smaller the leakage error, and the better the measurement.

Why the fluids should be clean without any solids or gas?

The oval gear flowmeter has high measurement accuracy and is suitable for the measurement of high viscosity medium flow, but it is not suitable for fluids containing solid particles (solid particles will lock the gears, so that the flow cannot be measured). If the liquid to be tested is contaminated with gas, it will also cause measurement errors.

What is the Oval Gear Flow meter Features?

1. High measurement accuracy: 0.2 and 0.5;
2. Oil Flow meter with Simple, robust and reliable operation;
3. It is especially suitable for measuring medium with high viscosity and is not sensitive to changes in viscosity of the liquid to be measured;
4. Easy to install. There is no need for a straight pipe section before and after the flowmeter. Even if the flowmeter is close to the valve, the elbow, the constricted pipe, or the enlarged pipe, there is no need to install a straight pipe section.
5. Cast iron oval gear flowmeter is widely used in various oil products and measurement of non-corrosive liquid medium.
6. Cast steel oval gear flow meter for measurement of high pressure and low corrosive medium
7. Stainless steel oval meters are widely used in the measurement of highly corrosive liquid media such as acids, alkalis, salts and organic compounds.
8. In order to prevent the gear of the flowmeter from being jammed by impurities, a filter must be installed upstream of the flowmeter.
9.  Explosion-proof grade: ExiaIICT
10.Medium temperature: -20 °C ~ +100 °C, under high temperature adjustment, high temperature cooling barrel can reach 100 °C ~ 260 °C

What is the limitation for the oval gear flow meter?

1. Complex construction and bulky size, heavy flow meter for shipping and move
2. It can only measure clean liquid fluids without too much corrosivity
3. When the bulky flow meter is working it could cause nearby pipelines fluctuation also noise .
4. If the gear is jammed, the fluids cannot pass through the pipelines, so a bypass should be installed for possible fluids jam.
