Introduction
Notes:

The Probeis an ultrasonic level monitor combining sensor and electronics in a single package. It is
designed to measure liquid levels in closed vessels. The sensor is PVDF or ETFE, allowing The Probe
to be used in a wide variety of industries. The optional sanitary version affords quick removal and
ease of cleaning as demanded by the food, beverage and pharmaceutical industries.
The sensor houses theultrasonic transducer and temperature sensing element. The Probe emits a
series of ultrasonic pulses from the transducer. Each pulse is reflected as an echo from the material
and sensed by the transducer. The echo is processed by The Probe using Milltronic's proven `Sonic
Intelligence' techniques. Filtering is applied to help discriminate between the true echo from the
material, and false...
