Fig. 10: Mounting in a standpipe
1 Holes (for mixing)
2 Standpipe - vertically mounted - max. deviation 10 mm (0.4 in)
3 Ventilation opening
A Rod probe with spacer (steel)
B Cable probe with centering weight
Note:
Measurement in a standpipe is not recommended for extremely
adhesive products. In case of slight buildup, you should choose a
standpipe with bigger diameter.
Instructions for the measurement:
•
The 100 % point with standpipes should be below the upper
ventilation hole.
•
The 0 % point in standpipes should be above the gravity or center-
ing weight.
•
A false signal suppression with installed sensor is generally rec-
ommended to achieve the best possible accuracy.
