LIQUID APPLICATIONS - SUBMERGENCE

In applications where flooding is possible the transducer

▼

  can be fitted with a submergence

shield. The shield acts as a bell to create an air pocket in front of the transducer face. The
associated transceiver

▼

  interprets this as a flooding condition, and reacts accordingly.

Refer to transceiver manual for programming requirements.
