Answer / narayan

Check Tx data sheet or engraved plate on the tx and it gives span limit as 2000mm, then we can change
if it is below 2000 mm, we can not change, or calibrate
it is sensor range

Answer / mudassir

yaa you can but you have check the model no. if it is30512G
THEN YOU CAN CALIBRATE IT upto6000mmwc

Answer / saumil

We connect 375hart protocol and given this new range and calibrate 20 mA at 2000mmwc

Answer / ramana

If the Tx. Range is 2000 mmWC we can change it. But we need
little calculation. There is one formula

square root of(P1/P2)= Q1/Q2

Where P1= Pressure 1
P2= Pressure 2
Q1= Flow at Pressure 1
Q2= Flow at Pressure 2

if we mount flow tube in arrow direction then flow comes in negative & if we mount it another direction then flow comes positive,So what will be the problem
