What is the best Oil Flow meter?
When measuring oil flow, there are many options to choose from, such as liquid turbine flow meters, oval gear flow meters, and Coriolis flow meters. Each type operates on a different principle and is suitable for measuring different kinds of oil.
But
which one is the best oil flow meter?
The answer is that :Coriolis flow meters are the best oil flow meters.
Coriolis flow meter has the highest accuracy. It offers the highest precision, with an accuracy of up to 0.1%, while oval gear flow meters have an accuracy range of 0.2% to 0.5%, and liquid turbine flow meters typically achieve around 0.5%. High accuracy oil flowmeter is often needs when custody transfer flow meter is demanded.
One of the biggest advantages of the Coriolis flow meter is its ability to directly measure the mass flow of oil. Oil mass flow measurement provides the best accuracy measurement; however oval gear flow meter and liquid turbine flow meter can only provide volume measurement.
In addition to flow measurement, Coriolis flow meter can also measure multiple parameters, including oil temperature, oil pressure, and viscosity. This makes it a highly functional and efficient option for oil flow measurement. However tranditional oil flow meter can only measure oil total flow and oil flow rate.
Contaminated oil often contains impurities, which can be fatal to flow sensors with moving parts. For example, the impeller of a liquid turbine flow meter can be damaged, and the gears of an oval gear flow meter can get stuck.
While Coriolis flow meter can also handle oil containing impurities, which is a significant advantage over the oval gear flow meter and TUF flow meter. Oval gear meters can easily get stuck when measuring dirty or contaminated oil, leading to operational issues and maintenance problems.
In terms of installation, the Coriolis flow meter does not require straight pipe sections, just like the oval gear flow meter. This simplifies the installation process and provides greater flexibility in different industrial setups. In contrast, liquid turbine flow meters require straight pipe sections both before and after the meter to ensure accurate measurement.
Another key advantage of the Coriolis flow meter is its ability to measure high-viscosity oil. Liquid turbine flow meters can only measure clean oil with a viscosity of up to 45 cP,so we normally use TUF flow meter as low viscosity oil flow meter, such as diesel flow meter, fuel flow meter, kerosene flow meter, vegetable oil flow meter, while oval gear flow meters can handle oil with viscosities of up to 2000 cP, oval gear flow meter can be used as analog diesel oil flow meter, analog fuel flow meter, crude oil flow meter, palm oil flow meter and so on. However, Coriolis flow meters can measure oils with viscosities in the tens of thousands of cP, such as lube oil, grease ,HFO flow measurement, paraffin oil flow measurement, polymer-based oil flow measurement and so on, making them suitable for a wide range of industrial applications, in a world it can measure all kinds of oil .
High temperature oil flow meter
Liquid turbine flow meters can measure oil at temperatures up to 150°C, while oval gear flow meters can handle high-temperature oils up to 200°C. Vortex flow meters, designed for low-viscosity oils, can operate at temperatures up to 350°C. However, Coriolis flow meters can also measure oils at temperatures as high as 350°C with oil kinds oil viscosity, making them suitable for applications such as furnace oil flow measurement or other high temperature oil flow measurement.
Overall, the Coriolis flow meter is the most accurate and reliable option for oil flow measurement. Its ability to measure mass flow, handle impurities, and accommodate high-viscosity oils makes it the best choice for industries that require precise and efficient oil flow monitoring.
The Coriolis flow meter is undoubtedly the best choice for measuring oil flow, but it is also the most expensive. Users can select the most suitable oil flow meter based on their specific applications, requirements and your budget.
