How to choose a small flow diesel flow meter? What kind of flow meter is suitable?

Three types of flowmeters are commonly used to measure diesel oil (oval gear flowmeter, liquid turbine flowmeter, float flowmeter),

Among which the oval gear flow meter has an accuracy of 0.5, and its cost performance is also Highest.

 

For the measurement of diesel flow with high viscosity, small flow and high accuracy requirements, you can consider choosing an oval gear flowmeter to measure its flow.

Reasons Affecting the Accuracy of Oval Gear Flow Meter

When using an oval gear flowmeter, it should be noted that the temperature of the measured medium should not be too high, otherwise it will not only increase the measurement error, but also cause the gear to be stuck. For this reason, the oval gear flowmeter is used within the specified operating temperature range of the instrument.

 

After long-term use of the oval gear flowmeter, the internal gears will be corroded and worn, which will affect the measurement accuracy.

 

Usually, the accuracy of the oval gear flowmeter can reach 0.5 grade, which is a relatively accurate flow meter. However, if the flow rate of the measured medium is too small, the influence of the leakage error of the oval gear flowmeter will be prominent , and it cannot be used anymore. Ensure sufficient measurement accuracy.
