d/p flow transmitter LP side give to pressure.what you
geting out put ? how you get(ma)?

Answer Posted / jazz

Dp transmitters work by measuring the difference between the
pressure measured on the high pressure port (HP) and the low
pressure port (LP). If for example the pressure on the HP is
100 psi and the pressure on the LP is 75 psi, the DP
transmitter will measure the difference of 25 psi. Let say
for example that the dp transmitter range is calibrated from
0 to 50 psi dp, the transmitter will output a proportional
12 mA (representing 50% of the dp range) The 24VDC supply on
serves to give power to the transmitter electronics so that
the transmitter will output a proportional 4-20mA signal
corresponding to the pressure difference sensed by the
pressure ports.
