The elliptical gear flowmeter, also known as the displacement flowmeter, is a type of volumetric flowmeter. It is one of the flowmeters with relatively high accuracy among all types. It uses mechanical measuring elements to continuously divide the fluid into individual known volume portions. The total volume of the flow is measured by the number of times the measurement chamber fills and discharges the volume portion of the fluid successively and repeatedly. The elliptical gear flowmeter can be manufactured using different materials (cast steel, stainless steel, and 316), and is suitable for flow measurement work in industries such as chemical engineering, petroleum, medicine, power, metallurgy, and food.
