EMCO WEDGE Differential Pressure Flow Meter Type EWF



Principle
 
EMCOWEDGE is used as primary element in flow measurement of liquid, gas and steam according
to the differential pressure principle.
 
 
Wedge type flowmeter
 

Construction

 
Design and calculation standards :
 
EN, PED 97/23 EC, ANSI/ASME and RW Miller
 
Sizes
DN 50 -900 2"-36"
 
Pressure rating :
PN 10 - 250, 150 -1500 lbs
 
Material :
Carbon steel P235GH, P250GH, P265GH, A105N, A106 Gr. B, AISI 316, Duplex, Super Duplex, 6Mo, heat resisting steels, other materials on request
 
Mounting style :
Flanges connection according to DIN or ANSI
 
Pressure taps :
DN 50 and DN 80, 2” and 3”
 
Flange facing :
Flat or raised face according to DIN 2526 or flat, raised face or ring type joint according to ANSI B 16.5
 
Element ratio (H/D) :
0,2, 0,3, 0,4 and 0,5 (0,4 is standard).
 

Technical Data

Accuracy :
 
+/- 4-5 % (un-calibrated), +/- 0,5 % (calibrated).
 
Repeatability :
 
+/- 0,2 %
 
Pressure loss :
 
40 % of measured differential pressure with ratio H/D 0,4
 
Limits for Reynolds No. :
 
Re > 500
 
Viscosity :
 
Up to 3000 Cp
 
Installation requirement :
down to 5 x D up-stream and 2 x D down-stream.
 

Advantages

Very suitable for viscous liquids. Not sensitive to solid particles in the fluid. Bi-directional flow possible.
 
For very low Reynolds Nos.
Suitable for erosive fluids.
No risk of clogging. Self cleaning.
