Oval gear flowmeters are a type of volumetric flowmeters, which are a class of high accuracy in flow meters. It uses a mechanical measuring element to continuously divide the fluid into a single known volume part, and measures the total volume of the flow according to the number of times the metering chamber fills and discharges the fluid in the volume one by one. Oval gear flowmeters can be made of different materials (cast iron, cast steel, 304 stainless steel, 316 stainless steel), and are suitable for flow measurement in industrial sectors such as chemical, petroleum, pharmaceutical, power, metallurgy, and food.
