NOTES:
-THE INSTRUMENT REQUIRES A MINIMUM OF 6 AND A MAXIMUM OF
10 LITERS PER MINUTE CONSTANT FLOW.
-THE DRAIN MUST FLOW FREELY TO AN OPEN DRAIN. ANY
BACKPRESSURE MAY CAUSE THE SAMPLE CHAMBER TO

4.3 Sensor Mounting & Plumbing
Locate the sensor as close to the sampling point as possible to reduce lag time. A site that
is protected from the elements (sun, rain etc.) is preferred, but the sensor is rated for use
under most outdoor conditions. The sample chamber is designed to be mounted with ¼”
diameter bolts. The sensor does not get firmly mounted, but just sits on top of the sample
pot. A light shield protects the clear sample pot cover & helps to prevent algae growth.
Refer to the diagram below for mounting dimensions.
