Operation Manual
INSTALLATION
Sensor can be directly top mounted if the size of the connection hole is bigger
than the diameter of the float.
In case the diameter of the float is bigger than connection size, firstly dismantle
float and mount. While installing back the float needs to be the right direction.
Float have a mark showing correct direction to be mounted
Position of the ring clip must be aligned with stem marked position
Sensor must not be mishandled, squeezed, bended or deformed. In case of any
deformation and abnormal functioning, sensor needs to be sent back to factory
for repair & calibration
Please do not replace the specifications of the float without permission; otherwise,
the product would fail to function properly.
The float should be prevented from striking or dropping on the ground so as to
avoid breaking the magnet inside the float and losing its function.
Please do not open the junction box to ensure ensure accuracy of the
measurement.
During transportation, sensor must be covered with anti vibration packaging such
as bubble packaging or spongy packaging etc.
When sensor is installed on non-metallic tank, the housing should be well
grounded.
