Answer Posted / aftab ahmed mazari
If you installed the remote seal transmitter at flanges,
then in case empty tank /vessel, the transmitter will
showing -mA. so do the followings:
1. Make transmitter 4 mA in this case(without any pressure,
only lower low leg remote seal pressure acting)
2. Apply 850 x 0.73 =620.5 mm of water to high side of
transmitter flange and set transmitter out put 20 mA.
