Answer Posted / yasir nazir

if the transmitter is installed below the tank,then we have
to calculate the HP side level below the tank zero level,and
applying
that much pressure on HP side to check the zero level.

And if transmitter is installed at zero tank level,then
isolating the HP side and draining the HP side gives the
zero level at transmitter.

Explain PID controller tuning & any one method used for it.
