nitrogen flow meter

VORTEX STEAM FLOW  METER INTRODUCTION

The vortex nitrogen flow meter is designed based on the Karman principle. The vortex steam flow meter can measure the flow, temperature and other parameters of the fluid of industrial pipelines. The vortex nitrogen gas flow meter has the function of pulse frequency output, 4-20mA analog signal output, RS485 communication, HART protocol and so on.

The vortex nitrogen gas flow meter utilizes a volumetric flow measurement principle driven by a natural phenomenon observed when a liquid moves around a bluff object. Meanwhile, the vortex compressed air flow meter functions based on the vortex shedding principle, where vortices are intermittently shed downstream of the object.
