INSTALLATION
Installation
The Conductivity sensor may be mounted in any position as long as water is always in contact when
measuring process water. Avoid connections in “dead leg” sections of pipe. An air pocket around
the electrode tips will cause erroneous readings. The sensor electrodes should be in direct contact
with the process flow (see DWG #04259 in the back of this manual).
The 543 series sensors have 6 wires. They are as follows:
•

Cable length of Conductivity sensors is measured from the electrode tips to the end of the wire.
Twenty (20) feet is the maximum cable length. Lakewood Instruments guarantees operation up to
20 feet. If a cable extension is used, Lakewood Instruments will not guarantee operation of the
sensor.
