When using a level sensor for measuring Ammonia in a compact plate and shell heat exchanger or other systems with turbulent conditions, we have new recommendation based on recent experience:
For Stand-pipes with stable conditions (smooth changes in the level):
• Use a HBLT-Wire or a HBLT-A2 rod-style sensor.
For Stand-pipes with turbulent conditions (a lot of turbulence, cooking, foaming, liquid from the top):
• Use a HBLT-A2 rod-style sensor, or
• Use only a HBLT-Wire sensor when you have it mounted in an inner guide-tube of e.g. DN25 as illustrated.
The guide-tube will dampen the turbulence and the foaming and you will have a good measurement.
• If the HBLT-Wire sensor is already mounted under these conditions WITHOUT a guide-tube,
do eventually set the filter time function between 60-120 seconds to dampen the signal from the turbulent conditions.
For Alfa Laval U-turn evaporator: Use a HBLT-A2 rod-style sensor.

Der Sensor kann auf die Ausgabe eines dem Behälterfüllstand entsprechenden linearen Signals programmiert oder für die Steuerung eines Ventils zur Aufrechterhaltung eines konstanten Füllstandes im Tank (Schwimmerventil) konfiguriert werden.
