3. Installation
Figure 1- Transmitter’s installation place
Please pay attention to following consideration in the installation procedure.
1- Choose the mounting place so the tank contents never reaches dead band of the transmitter, so
the distance between lowest end of the probe and the liquid surface should be never less than
these recommended values:
