14 SOI/266-XC Rev. I | 2600T Series Pressure transmitters
5 Applications
5.3 Liquid level measurements on closed tanks and
non condensable fluids (dry leg)
− Mount the transmitter at the same height or below the lowest
level to be measured.
− Connect the + (H) side of the transmitter to the bottom of the
tank.
− Connect the - (L) side of the transmitter to the upper part of the
tank, above the maximum level of the tank.

5.4 Liquid level measurement with open tanks
− Mount the transmitter at the same height or below the lowest
level to be measured.
− Connect the + (H) side of the transmitter to the bottom of the
tank.
− Vent the “–” (L) side of the transmitter to the atmosphere (in this
case a gauge pressure is shown; the (L) side is already vented to
the atmosphere).

5.5 Pressure or absolute pressure measurement of a
condensable vapor in a pipe
− Place the tap at the side of the line.
− Mount the transmitter below the tap.
− Connect the + (H) side of the transmitter to the pipe.
− Fill the vertical section of the connecting line to the tap with a
compatible liquid through the dedicated filling tee.
