Huasheng Instrument-- Oval Gear Flowmeter

Oval gear flow meter

Oval gear flowmeters (also known as displacement flowmeters, gear flowmeters) are volumetric flowmeters of one type and have a higher degree of accuracy in flowmeters. It uses a mechanical measuring element to continuously divide the fluid into a single known volume portion, and the total flow volume is measured according to the number of times the metering chamber fills and discharges the volume portion fluid successively and repeatedly. Oval gear flow meters can be made of different materials (cast iron, cast steel, 304 stainless steel, 316 stainless steel). It is particularly suitable for flow measurement of heavy media, polyvinyl alcohol, and resins with high viscosity.

Features:

In accordance with the requirements of the correct installation of the elliptical gear flow meter, when used to ensure adequate accuracy, the cumulative accuracy of the cumulative accuracy of up to 0.5, is a more accurate flow metering instrument. However, if the flow rate of the measured medium is too small, the instrument's leakage error will be prominent and sufficient measurement accuracy cannot be guaranteed. Therefore, the elliptic gear flowmeters of different model specifications have a permissible value for the minimum use flow rate. Only when the actual measured flow rate is greater than the lower limit flow allowable value, the measurement accuracy can be guaranteed.

Second, the use of oval gear flow meter should pay attention to the measured medium temperature can not be too high, otherwise it will not only increase the measurement error, but also make the gear stuck. For this reason, oval gear flowmeters are 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. Therefore, always pay attention to observation and remove it regularly for inspection. If conditions permit, it is better to perform calibration regularly.
