When the liquid to be measured enters the elliptical gear flow meter through pipes, the pressure difference created at the inlet and outlet drives a pair of gears to rotate continuously, thereby transporting the liquid that has been measured in the initial crescent-shaped chamber to the outlet. The total flow rate of the liquid being measured is equal to the product of the number of rotations of the elliptical gears and four times the volume displaced with each rotation. Therefore, it is easy to see from the measurement principle of the helical gear flow meter that it relies on the head pressure of the fluid being measured to drive the helical gears to rotate for measurement, and this is independent of the flow state of the fluid. Technicians from Evergrande Instruments advise that for fluids containing solid particles, elliptical gear flow meters should not be used, as these particles can jam the gears and prevent accurate flow measurement ； It should also be noted that for media containing gas in the liquid, the use of elliptical gear flow meters is not recommended either, as their measurement errors can be quite large. When using an elliptical gear flow meter to measure liquids with high viscosity, the amount of leakage from the gaps between the gears and the measurement chamber is low. Therefore, the higher the viscosity of the liquid being measured, the smaller the leakage error, which is beneficial for measurement and results in higher accuracy. It can be said that the elliptical gear flow meter is the best choice for measuring the flow rate of highly viscous liquids.
