Answer / 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.

Answer / manish dave

First isolate HP side of Tx. and open vent port of HP side.
LP Side fill service liquid up to LP tapping and set the
zero.

In this case your HP & LP both sensor working or not it was
clearly identified.
While applying span pressure on LP side in this case if HP
side sensor fails than transmitter will not work after zero
checking.

Answer / gnanvendan

close HP line isolation valve and drain in transmitter,then
check the LP side pressure according to LRV whether its
same or not.

Answer / praveen kumar

Close both the isolation valves of Transmitter, and open
the line vent in LP side

Answer / manish dave

yes dear

First u knew range of transmitter then apply span at LP side

Answer / id10t

Open bypass so HP=LP.
