Tank Installation

Below are some considerations with respect to how the sensor can be installed on top of a tank. ProScan
out from the measurement transducer of the sensor. As a result, the height of the sensor above or below the top of the tank will affect the
dead band and 20mA settings.
Below are some examples of different tank configurations. The ProScan
band or dead zone. This is the area just below the tip of the sensor that consists of signal echo's that are returned too quickly
to differentiate the false signal from the measuring echo, therefore this space is not measured.
Special consideration is required during the installation to ensure the blanking area is taken into account.
The position of the sensor above or below the top of the tank will affect the blanking area and the 20mA setting.

Measuring the tank is one of the most important aspects in configuring the sensor. When measuring the tank, take into account the
location of the sensor with respect to fittings, risers, dome tops and bottoms, and identify where the measurements are taken from the sensor.
