Elliptical gear flowmeter is a volumetric measuring instrument used for continuous or intermittent measurement and control of liquid flow in pipelines. Advantages: Large range, excellent accuracy, low pressure loss, strong viscosity adaptability, ability to measure high temperature and high viscosity liquids, easy calibration, and simple installation. Suitable for measuring flow in petroleum, chemical, synthetic fiber, transportation, commerce, food, medical and health industries. The elliptical gear flowmeter can display cumulative flow rate, instantaneous flow rate, single flow rate, etc. on site, and can also output pulse signals, 4-20mA analog signals, 420mA+HART, MODBUS RS485 communication, etc. Combined with mechanical or electronic batch controllers, it can achieve various functions such as canning and batch control in different types.
