Introductions

Remote Type Vortex Flow Meter is used in numerous branches of industry to measure the volume flow of liquids, gases and steam.

Applications in the chemicals and petrochemicals industries, for example, in power generation and heat-supply systems involve widely differing fluids: saturated steam, superheated steam, compressed air, nitrogen, liquefied gases, flue gases, carbon dioxide, fully demineralized water, solvents, heat-transfer oils, boiler feedwater, condensate, etc.

Features

Vortex flow meter body is robust and universally applicable for liquids, gases and steam,optimized for steam applications.
In gas measurement, vortex flow meter could achieve high accuracy ±0.75%~±1.0% of reading ( gas ±1.0%, liquid ±0.75%); which could use in custody transfer , while the metal tube rotameter or orifice plate usually use for process control.
To protect the sensor, WESDUN vortex flow meter choose embedded sensor, with piezo-electric crystal encapsulated inside the sensor, which is our own patent.
There is no moving parts, no abrasion, non-wearing parts inside the vortex flow meter sensor, fully welded SS304 body (SS316 select able).
With patented sensor and flow sensor body, it could eliminate drift & vibration influence from great aspect in the working site while compare with other flow meters.
With a variety of signals outputs and selection, such as 4-20mA, pulse with HART or pulse with RS485 are selectable.
