6.2 Attaching the sensors
When mounting the sensors, note the following:
A
z Attach the sensors on a vertical and smooth surface on the tank.
z Avoid mounting them on concave surfaces.
z Guide the cable downwards or at a downward angle (fig. 4, page 4).
z Position the sensors at the tank (fig. 4 A, page 4). The sensors do not
need to be placed in the middle of the tank (fig. 4 B, page 4). They can
even be placed on different sides of the tank (fig. 4 C, page 4).
z Some metal tanks have inner partition walls (surge plates) to minimise the
movement of the liquid. An outer weld joint indicates that there is a parti-
tion on the inside of the tank. Position the sensors‘s center at a distance
of at least 7 cm (2 ¾") from the partition.
z Position the sensors‘s center at a distance of at least 7 cm (2 ¾") from the
edge of the tank and pipe connections (fig. 5, page 4).
z The Tank Calculator (http://www.fmmarin.se) helps to find the right level
for the sensors on a non-rectangular tank.
Mount the sensors as follows:
➤ Use a cloth to clean the tank wall in the places where you want to attach
the sensors.
➤ Roughen the smooth surface on plastic or fibre-glass tanks with sandpa-
per to ensure the sensors bond properly.
➤ Carefully remove the protective film from the adhesive strip on the sen-
sors.
➤ Position the sensors at the ¼, ½ and ¾ filling levels on the tank (fig. 4,
page 4).
➤ Press each sensor firmly onto the tank wall for a few seconds.
NOTICE!
z The sensors are sensitive to hard knocks and will be damaged
if they are subject to impact or fall on the ground.
z The sensors do not resist water.
z Temperatures above +20 °C (68 °F) are necessary for the
sensors to bond well. If necessary, use a heat gun or a heater
to warm up the tank wall.
