As a new type of differential pressure flowmeter

it is necessary to study on the pressure loss of double-cones flowmeter in the shortage of energy increasingly today.Based on standard k-ε turbulence model

with water as the medium for simulation

the fluent 3D pipeline simulation experiment is carried out

aiming at the double-cones meter

with pipe diameter is 52 mm and the equivalent diameter ratio is 0.69

to research on the pressure loss.In the condition of the same effective flow area

pressure loss and relative pressure loss values of the orifice and nozzle are obtained

which are compared with double-cones.Results indicate that the pressure loss of double-cones flowmeter is only 1/5 of that of orifice and 2/3 of nozzle.Besides

in the condition of effective flow area is nearly the same

the result shows that compared with the V-cone meter.The pressure loss and relative pressure loss of the orifice are the most and the double-cones flowmeter are the least in these four kinds of flowmeters

and the V-cone flowmeter is between orifice and nozzle.
