VN series Coriolis force mass flowmeter

VN series Coriolis mass flowmeter is NEXON's new generation of micro-curved double flow tube Coriolis mass flowmeter. It is equipped with an electronic conversion device based on digital signal processing (DSP), which integrates the digital closed-loop vibration control (DLC), signal processing, calculation and diagnostic function of the sensor, and has the advantages of high measurement accuracy, wide range ratio and high reliability. It can communicate with the manual operator through HART or PC through Modbus, and directly perform online node configuration, fault diagnosis and data recording. The volumetric flow rate, cumulative mass, cumulative volume and component ratio of the fluid can be calculated while measuring the mass flow rate, density and temperature of the fluid in real time.
Applications

Process control

Material ratio

Concentration measurement

Batch filling
