CONDUCTIVITY METER:
The meter is used on sites exposed to rain, dust, and robust handling. Basically, it comes in two parts i.e. Meter & Sensor.
Sensor:
It is the sensing element of meter, which senses the conductivity and sends the signal to the meter.
Meter:
This is the unit that processes the information received from the sensor and displays the actual conductivity in the line.

Trouble Shooting:
TROUBLE |
PROBABLE CAUSE |
ACTION |
DURING COMMISSIONING |
Fluctuating
Reading |
Sensor not dipped in the line properly |
Loop the outlet tubing such that the tee always remains |
Wrong wiring |
Connect the wires as per drawing |
DURING NORMAL SERVICE |
Display
Shows
Erroneous
Reading |
Sensor not dipped in the line .properly |
Loop the outlet tubing such that the tee always remains flooded with water |
Deposition on the sensor |
Remove the sensor and clean it with Polish paper |
No Display |
High Voltage |
Check MOV/ FUSE, if it is burnt then replace it with new one |
Frequent
Fuse failure |
MOV short |
Replace MOV*
