Installation considerations
A Multiple Spot Temperature sensor (MST) and Water Level Sensor (WLS) must be installed on the tank
before installing the Rosemount 2240S Multi-input Temperature Transmitter.
The MST/WLS is normally anchored to the bottom of the tank by attaching a weight at the end of the
tube. A tank expands when it is filled or warmed up, causing the roof to move slightly upwards. The
weight has a shackle which allows the tube to follow the expansion, preventing it from breaking.
Multiple Spot Temperature sensor (MST)
Be careful with the flexible protection tube
Temperature and Water Level Sensors should be located as far away as possible from heating coils and
mixers.
In case the flexible tube is damaged, please contact Emerson Automation Solutions/Rosemount Tank
Gauging.
Do not attempt to fix or rebuild the temperature sensor since this may cause serious malfunctions
Water Level Sensor
Handle the Water Level Sensor carefully
Leave the sensor protection on until the final positioning in the tank
