4 Sensor installation
4.1 Installation considerations
A Multiple Spot Temperature sensor (MST) and Water Level Sensor
(WLS), such as Rosemount 565, 566, or 765, must be installed on the
tank before installing the Rosemount 2240S Multi-input Temperature
Transmitter.
The sensor 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.
Multiple Spot Temperature sensor
•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
4.2 Multiple Spot Temperature sensor
A Multiple Spot Temperature sensor (MST) typically measures the
temperature with a number of Pt100 elements placed at different
heights to provide a temperature profile and average temperature of
the product. The spot elements are placed in a flexible gas tight tube
made of stainless steel which can be anchored to the tank bottom.
Up to 16 Pt100 temperature elements can be connected to a
Rosemount 2240S Multi-input Temperature Transmitter.

illustrated in Figure 4-3. Emerson Automation Solutions may in some
cases recommend even more temperature elements for Custody
Transfer tanks, depending on how the tanks are operated.

WinSetup software to configure temperature elements for average
temperature calculations.
4.3 Water Level Sensor
The water level sensor (WLS) probe, with integrated temperature
elements, is attached at the lower end of the flexible protection tube.
A weight is attached to stabilize the tube as illustrated in Figure 4-4.
At the upper part of the sensor probe, nuts are placed at the middle
of the threaded section, 350 mm below the top of the probe. This is
intended as a starting point for adjusting the vertical position of the
probe.
As an option, the tube may be stabilized by putting a concentric
weight above the WLS probe, instead of at the end, in order to ensure
that measurements are performed as close to the tank bottom as
possible. Also, the eyebolt at the end of the tube can be removed.

3. When the tube is placed on the nozzle, adjust the vertical
position with the lock nuts. If a weight is placed at the end
of the tube, it should barely touch the tank bottom.
Note
Ensure that the flexible protection tube is in a vertical position
to obtain correct measurement data.
4. Install the Rosemount 2240S Multi-Input Temperature
Transmitter.

5 Rosemount 2240S Installation
5.1 Installation considerations
The information in this section covers installation considerations
for the Rosemount 2240S Multi-input Temperature Transmitter in
order to achieve a proper installation and optimum measurement
performance.
In order to reduce the required cabling, Rosemount Tank Gauging
devices, including the Rosemount 2240S, are designed for daisy-
chain connection of the Tankbus and shield grounding to other field
devices.
The Rosemount 2240S is designed for installation:
•on top of the MST/WLS
•on top of Rosemount 614 cone
•remote on a pipe or wall
With remote mounting of the Rosemount 2240S, the nut and sleeve
at the bottom of the 2240S can be replaced by a M32 cable gland, see
Components. See also Ordering Information in the Rosemount 2240S
Product Data Sheet.
When the Rosemount 2240S transmitter is installed in a hazardous
area, ensure that the installation requirements according to
Hazardous areas are complied with.
Ensure that the recommended cable glands/conduits are used.
Ensure that the Tankbus is correctly terminated, see Termination.
Ensure that grounding is performed according to national and local
electrical codes, see Grounding.
Do not install the Rosemount 2240S in non-intended applications,
for example environments where it may be exposed to extremely
intense magnetic fields or extreme weather conditions.
Ensure that the Rosemount 2240S is installed such that it is not
exposed to higher pressure and temperature than specified in
Product Data Sheet.
It is the responsibility of the user to ensure that the device meets the
specific inside tank installation requirements such as:
•chemical compatibility of wetted materials
•design/operation pressure and temperature
