SUP-LUGB Vortex Steam Flow Meter

Grow your business with high-quality & visibility vortex steam flow meters. Durable material. One-Stop service From R&D To Production. Trusted By Global Companies.


Flange external clamping vortex steam flow meter is characterized by small pressure loss, large range, high accuracy, in the measurement of work volume flow is almost independent of the fluid density, pressure, temperature, viscosity and other parameters. This vortex flow meter is widely used to measure steam, gas and lower viscosity liquid. Instrument parameters can maintain long-term stability. The vortex flow meter has analog standard signal, also has digital pulse signal output, easy to use with computers and other digital systems, is an advanced, ideal measuring instrument.

  • Accuracy: 1.0%  1.5%

  • Range Ratio:  1:8

  • Ingress protection: IP65

Measuring principle

A fluid flowing with a certain velocity and passing a fixed obstruction generates vortices. The generation of vortices is known as Karman’s Vortices.The frequency of vortex shedding is a direct linear function of fluid velocity and frequency depends upon the shape and face width of bluff body. Since the width of obstruction and inner diameter of the pipe will be more or less constant, the frequency is given by the expression:
