Part 3 – Sensor Mounting
3.1 General
Select a location within the maximum sensor cable length for mounting of the
sensor. Locating the sensor within 25 ft. of the transmitter is generally preferred
for ease of operation and calibration.
3.2 Submersion Mounting
Most applications for D.O. monitoring are done using a submersible sensor. This
method can be used where flow is reasonably constant, and hydraulic head does
not vary more than about 10 feet. Oxygen sensors can never be used in
completely stagnant conditions. A flow velocity of at least 0.3 feet per second is
normally required for measurement.
