INSTALLATION - SENSOR LOCATION
1. Choose a sensor mounting location where silt or deposits are least likely to accumulate.
2. For best results flow should be evenly distributed across the channel and relatively free of turbulence.
(The Stingray is very effective at averaging level and velocity readings in turbulent conditions, but best
accuracy and response time is achieved with evenly distributed flow.)
3. Avoid vertical drops, obstructions or elbows immediately up and downstream from the sensor. Locate
the QZ02L sensor at least 10 times maximum Head (level) and 10 times the channel width from these
flow disturbances.
QZ02L VELOCITY-LEVEL SENSOR MOUNTING
Mount the QZ02L sensor with the
stainless steel bracket and hardware
supplied. Ensure that the sensor is parallel
to the water surface (check with a level).
Mount with the tapered end of the sensor
pointing upstream and the sensor cable
pointing downstream.
Clip or tie wrap the sensor cable securely
to the pipe or channel wall.
