remains in place. If it comes away then replace it before continuing. If there are any visible
bubbles in the electrolyte, remove them using a stirring motion with the packing component.
6.
Hold the container steady between thumb and forefinger of one hand. Lower the sensor into the
container until the top of the anode is covered with electrolyte.
7.
Gently screw the sensor clockwise into the replacement cartridge, applying minimum pressure to
avoid any damage to the screw threads.
8.
Continue turning until the cartridge is attached to the sensor, and the sensor is automatically
released from the container. The empty container, the screw top and packing component can be
discarded.
Note: It is normal that some of the electrolyte will overflow from the replacement cartridge and into the plastic
container.

Rinse the sensor under a tap for about 5 seconds to remove any excess electrolyte, then gently
wipe with a soft tissue to ensure all parts are completely dry. Drain the overflow electrolyte from
the container into a sink and flush away. Discard the used container.
10.
Take a new Dacron
®
mesh patch from the box of O-rings in the recharge kit. Place the mesh in
the center of the protection cap. It is very important that the mesh is in the center of the protection
cap and covering the entire grille. Lower the sensor onto the protection cap making sure not to
disturb the mesh.
11.
Push the protection cap firmly into place, making sure one of the four slots in the protection cap
fits over the small locking pin (highlighted right). If it is necessary to turn the protection cap to fit
over the locking pin, ensure you only turn it clockwise to avoid unscrewing the cartridge.
12.
Finally, screw the protection cap locking washer back into place in a clockwise motion, and
tighten finger tight.
4.2 Sensor installation
4.2.1 Sensor positioning
The sensor must be installed in a socket or flow chamber that allows contact with the sample fluid to
be analyzed. The sensor and measuring instrument are connected by a cable and two 10-pin
connectors. The standard sensor cable length is 3 meters though extension cables of up to
1000 meters are available. However, smart sensor technology is only available with distances of up
to a maximum of 750 meters. Ensure that the sensor will be mounted:
• perpendicular to the pipe
• on a horizontal pipe section (or on flow-ascending vertical pipe)
• minimum of 15 meters away from the pump's discharge side
• in a place where the sample flow is stable and rapid, and as far as possible from:
• valves
• pipe bends
