Venturi
Tube - This differential pressure element
actually forces the flow into a smaller diameter
section of pipe, then measures the pressure differences
between the unrestricted flow and the restricted
flow. This element can be used for very accurate
measurements if calibrated correctly. |

Fox
Valve manufactures highly engineered venturi
flow controls, including:
a) Custom manufactured ∆P venturi flowmeters
for demanding applications where off-the-shelf
equipment is not adequate;
b) Sonic chokes/Laval nozzles - the simple, reliable
way to regulate/set stable, accurate (not measure)
gas flow rates, unaffaected by ∆P, eliminating
the valve+flowmeter+PLC complexity;
c) Cavitating venturies - like sonic chokes, but
for liquids. Since 1961.

Venturi Calculator
 |
Use the flow through Venturi tube calculator for both liquids and gases. Fluid is considered as incompressible, so density (rho) and temperature (T) are constant through the tube. Also, the gas is considered as ideal.
Units of measurement are both in SI and English .
The Flow through Venturi tube calculator can be used for calculation of:
volumetric flow - Q
mass flow - G
velocity on inlet, bigger diameter - V1
velocity on smaller diameter - V2
For calculation of those values, necessary values for input are:
inlet, bigger diameter - D1
smaller diameter - D2
inlet pressure - p1
either pressure on smaller diameter - p2, or pressure drop p1-p2
kinematic viscosity - ni, or dynamic viscosity mi
for gases only:
either temperature - T, or density - rho
gas constant - R
for liquids:
density - rho
Beside four values (Q, G, V1, V2), which calculation is main purpose of calculator, values that are not defined by user are determined in process of calculation (for example: if pressure p1 and temperature T are specified for gas flow - value for rho is calculated together with four main values (Q, G, V1, V2)
