The Principal Operation:

• Vortex Flowmeter is based on “Karman” principle. Flow transmitter is composed of a body with the same nominal diameter and a column with triangular transect. When a column object placed in flowing fluids ( including gas and liquid ) in pipe, a series of vortexes will be generated alternately on each side of the object as shown below

Standard condition:

• Gas: normal temperature and pressure (t=20 deg C, Pn=0.1 MPa,Po=1.292 kg/m3)

• Liquid: normal temperature (t=20 deg C,Po=1000 kg/m3)

• Steam: saturation steam (t=143 deg C, Pn=0.4 MPa,Po=2.124 kg/m3)

Output: 

• Three-wire system frequency output

• 4~20mA output

• 4~20mA output + HART

• No output signal

Display:

• Scene shows (intelligent)

• No scene shows

Medium: 

• Liquid

• Gas

• Steam

Protect class: 

• IP65 (Integral type)

• IP68 (Separable type)

• IP68 (Submerged separable type)
