Answer / vishnu

It is not possible to measure flow using pressure transmitter.We need DP transmitter to measure flow.First we have to create a DP using ventury tube or a orifice plate.the flow rate is directly proportion to the squreroot of the Diffrential pressure.

Answer / mokie

use differential pressure transmitter with oriface, vcone or
the other means

Answer / sudarsun

Differential Pressure transducer along with a Venturi pipe
should do the work. The pressure at the normal diameter vs
the pressure at the shorter diameter should be proportional
to the rate at which the fluid flows.

Answer / ahmed

You can't use the pressure transmitter to measure the flow
because when you want to measure the flow you need delta be
in the pressure and the presser transmitter have one side
you want transmitter with high and low sides

Answer / jobby c johnson

In any Flow meters(venturi, Oriface etc), Flow rate is given by the expression

Q is propotional to sqrt(delta p)

Where Q is mass flow rate ; delta p is the differantial pressure across the transmitter
