The ultrasonic measuring system is often used for the measurement of levels, especially in dynamic regime channels; it is available in various measuring ranges, and can also be used in channels with small levels (up to one meter), always with acceptable accuracy.
Easy to install and easy functional verification, it is particularly used in dams, both in tributary channels and in tunnels for the measurement of levels .
The instrument is particularly suitable for monitoring levels in tunnels in concrete, RCC and
Earthfill dams, for monitoring leaks and drainage. It is also used for measuring levels in reservoirs.
Especially recommended for:
The ultrasonic sensor also allows measurement of levels in dynamic regimes. The instrument is characterized by:
The sensor is composed by an antenna which emits ultrasonic pulses at short intervals between them; the pulses are generally directed perpendicular to the water surface whose level is being measured. The pulse is reflected by the free surface of the liquid and bounces towards the instrument which picks up the return signal. The running runtime of the signals is proportional to the distance from the emitter at the free surface of the liquid.
A special procedure for processing data ensures reliable and precise measurement.
