Oval Gear Flow Meter for Diesel Oil Flow Measurement: Case Study

Oval Gear Flow meter is a type of positive displacement flow meters, it can measure varies kinds of oil, such as diesel oil, vegetable oil, edible oil, palm oil, gasoline, heavy oil.

Oval gear flow meters are widely used in factory, custody transfer, and marine industry and so on. The traditional flow meters ofen comes with mechanical registers and possible with return-to-zero totalizer. Now we also have oval gear flow meters with digital display, 4-20mA analog output or pulse output, RS485 MODBUS RTU communication and even HART PROTOCOL.

For diesel oil applications, oval gear meters are very suitable. The diesel viscosity typically ranges from 2-4 cSt at 40°C and changes with temperature. The meters maintain good accuracy across this range. They can handle diesel with minor particulates and operate reliably from -20°C to +80°C. With ±0.5% accuracy, they meet custody transfer requirements for truck loading, fuel dispensing, marine bunker metering and factory monitoring.

Oval Gear Flow Meter Advantages in Diesel Measurement

a. Oval flow meter measurement provides high accuracy, the basic error is generally 0.5% R, special up to 0.2% R or higher up special request. Particularly suitable for use in sites where high precision measurements are required.

b. There is no requirement for the viscosity of diesel oil,  even high viscosity can also be accurately measured.

c. Pipe vibration and interference at the installation site have no effect on this flowmeter. Oval gear flow meter do not need straight pipe requirement.

d. with on-site flow direct reading with mechanical register, no need for external power supply, you can measure the cumulative total, clear display, easy to operate.

e. Currently China oval gear flow meter manufacturer develop oval meters with more powerful functions, such as digital display, 4-20mA output or pulse output, RS485 and even Hart protocol.

Alternative Flow Meter Solutions for Diesel Oil

Due to the heavier weight of oval gear flow meters, some customers now choose liquid turbine flow meters as a lighter alternative for diesel oil measurement. However, liquid turbine flow meters can only work with low viscosity and clean oils, while oval gear flow meters can measure fluids with viscosity up to 2000 mPa.s.

And for more complicated applications, such as bitumen flow measurement, customers can go to coriolis mass flow meters.

Silver Automation Instrument is a professional oval gear flow meter supplier. We can manufacture different size oval flow meters (max to DN200,8 inch oval flow meter ) with different materials available, such as cast iron, cast steel, stainless steel 304, stainless steel 316.
