Insertion flow meter

Insertion flowmeters include insertion vortex flowmeter, insertion turbine flowmeter, insertion electromagnetic flowmeter, insertion ultrasonic flowmeter, pitot tube, Annubar tube and insertion thermal flowmeter, etc.

Insertion flow meter Overview

Insertion flow meter are 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.

Insertion Flowmeter 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.
Vortex meters are essentially frequency meters, since they measure the frequency of vortices generated by a “bluff body” or”shedder bar”.
