Drinking and Feeding measurements
•
The drinking and feeding sensors can be used with the dispensers supplied by TSE only - if
others are used, measuring errors will occur.
•
(Re)assembly of rod drinking nipples
NOTICE
- Dehydration hazard!
If the O-ring of the valve rod is positioned in the false orientation, flow through the opening of
the extension cap is always blocked and animals can die of thirst.
•
Position O-ring onto the gasket so that its smaller base is orientated towards the gasket.
•
After (re)assembly, always perform a test to ensure that liquid can flow throughout the nipple.

How to test the operability, i.e. flowability, of the drinking nipple?
•
Fill dispenser with water.
•
If not already done, attach drinking cap including nipple.
•
Suspend dispenser from sensor.
•
Wait approx. 20s until water and air are in equilibrium.
•
With a moistened finger, touch the tip of the nipple slightly (thereby moving the valve
rod to the side). It should be possible to "pull off" a drop. If not, a check for potential
sources and remedies, respectively, has to be made.
