Answer / a.mondal

know that pressure=(hight x sp.density x g),where g and sp. density are constant so that pressure is proportionaly related to the hight or level.

Answer / santosh kumar

Yes it can be measured for level measurment by using
Pressure transmitter of 0-60kg/cm2. If the level measurment
for open tank with HART communicator convert into mmH2O and
feed the RANGE for level measurment(Tank heightXdensity of
liquid in Tank)

Answer / rohan

Nowadays transmitters are having inbuilt math processor having
program stored in its memory.So in this case

P=h*density*g

This will convert pressure into level.

Identify and use the ANSI/ISA-S5.1 consensus industrial standard process symbols.
