What is the difference between elliptical gear flowmeter and waist gear flowmeter? Firstly, there are significant differences in appearance between the elliptical gear flowmeter and the waist wheel flowmeter. Secondly, during the dry period of use, the noise generated by the waist wheel flowmeter is not as loud as the noise generated by the elliptical gear flowmeter when the two gears are interlocked due to the two gears being buried together. Finally, regarding the two flow meters with the same diameter, the flow range of the waist wheel flow meter is larger than that of the elliptical gear flow meter. Although there are many differences between the two flow meters, they both tend to measure media with relatively high viscosity, especially suitable for measuring media with self-lubricating properties. It is best not to contain solid impurities in the media, otherwise it will cause gear wear and even damage. In short, there are many similarities between elliptical gear flow meters and waist wheel flow meters, but the differences are also significant. Therefore, when choosing between these two flow meters, it is important to understand the similarities and differences between them to prevent buying the wrong one and not meeting your own usage requirements.

2. What is the measurement method of elliptical gear flowmeter? The elliptical gear flowmeter is a volumetric flowmeter, also known as a displacement flowmeter. It is a type of flow meter with high measurement accuracy in the Ziyou Instrument series. When the measured liquid enters the elliptical gear flowmeter through the pipeline, the pressure difference generated at the inlet and outlet drives a pair of gears to rotate continuously, continuously delivering the liquid measured by the lunar cavity to the outlet. The product of the number of revolutions of the elliptical gear and four times the displacement per time is the total flow rate of the measured liquid. Therefore, it is not difficult to find from the measurement principle of the elliptical gear flowmeter that it relies on the pressure head of the measured medium to push the elliptical gear to rotate for measurement, regardless of the flow state of the fluid. Through the above introduction, we have found that this flowmeter belongs to the mechanical principle instrument and can only be used for measuring high viscosity liquid media. The elliptical gear flowmeter uses mechanical measuring elements to continuously divide the fluid into individual known volume parts, and measures the total flow volume based on the number of times the measuring chamber sequentially and repeatedly fills and discharges the slow part of the volume chain fluid. The elliptical gear flowmeter can be made of different materials (cast steel, stainless steel, and 316) and is suitable for flow key measurement in industrial sectors such as chemical, petroleum, pharmaceutical, power, metallurgy, and food. When we use an elliptical gear flowmeter to measure liquids with high viscosity, the amount of leakage from the gap between the gear and the measuring space is reduced. Therefore, the higher the viscosity of the measured liquid, the smaller the leakage error, which is more advantageous for the measurement and the higher the measurement accuracy. It can be said that the elliptical gear flowmeter is the best choice for measuring the flow rate of high viscosity liquids. As a manufacturer and technical personnel, we prioritize product selection.
