Characteristics and installation points of oval gear flowmeter

After the oval gear flowmeter is correctly installed as required, it can guarantee sufficient accuracy when used. Usually, the accuracy of the accumulated value can reach 0.5 level. It is a relatively accurate flow meter. However, if the flow rate of the measured medium is too small during use, the influence of the leakage error of the meter will be prominent, and sufficient measurement accuracy can no longer be guaranteed. Therefore, oval gear flowmeters of different models and specifications have an allowable value for the minimum use flow rate. Only when the actual measured flow rate is greater than the allowable value of the lower limit flow rate, the measurement accuracy can be guaranteed.

Secondly, when using the 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 may cause the gear to get stuck. For this reason, the oval gear flowmeter is used within the temperature range specified by the instrument. After long-term use, the gears inside the oval gear flowmeter will be corroded and worn, thus affecting the measurement accuracy. Therefore, it is necessary to pay attention to observation and regularly dismantle it for inspection. If conditions permit, it is best to calibrate it regularly. Features of oval gear flowmeter: 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 drive the oval gear to rotate for metering. The more viscous the medium, the smaller the leakage from the gap between the gear and the metering space. Therefore, the greater the viscosity of the nuclear measured medium, the smaller the leakage error, and the more favorable it is for measurement. The oval gear flowmeter has high metering accuracy and is suitable for measuring the flow of high-viscosity media, but it is not suitable for fluids containing solid particles (solid particles will jam the gears, making it impossible to measure the flow). If there is gas mixed in the measured liquid medium, it will also cause measurement errors. Installation of oval gear flowmeter: The pipeline of the oval gear flowmeter should be cleaned before installation. If the liquid contains solid particles, a filter must be installed upstream of the pipeline; if it contains gas, an exhaust device should be installed. The oval gear flowmeter has no specific requirements for the front and rear straight pipe sections. It can be used horizontally or vertically. The oval gear flowmeter

The more viscous the medium, the smaller the leakage from the gap between the gear and the metering space. Therefore, the greater the viscosity of the measured medium, the smaller the leakage error, which is more beneficial to the measurement.
