Hawk Sultan - Minimum Measurement Range; Transducer Frequency Ranges

Minimum Measurement Range
Sultan Acoustic Wave Series
20
Each Transducer frequency has a different Blanking distance and recommended minimum distance (or high
level) between the sensor face and measured product. This distance is measured from the sensor face or the
bottom tip of flange down depending on model.
