Product Description

HS-9500 series  radar water level sensors are designed for continuous water level measurement. The product uses the pulsed radar principle to determine the water level without making direct contact with the water. It is insensitive to mud, drift material, weeds and aggressive substances such as sewage and brackish water.

Clear and Easy Installation

Installation is easy with minimum construction work. The few construction elements, e.g. a bridge jib, do not interfere with measurement; interference could result in a narrowing of measured cross-section, and do not disturb the hydraulics. Possible false echoes caused by nearby supports etc, are removed by internal configuration of the software. HS-9500 is excellent where driftwood, debris, water traffic, or ice could damage stilling wells or other structures. The sensor can easily be relocated in the event of a storm changing the flow pattern, or if the river bed is sandy.

Reliable Measurement Accuracy

The measurement accuracy is not influenced by air humidity (including fog), precipitation or air temperature fluctuations within the measuring range. Further advantages include the low energy consumption, short measuring cycle, no dead angles and the short mounting distance.

Technology

The measuring principle is based on the pulsed radar principle. Measurement is done in pulses, the so-called pulse procedure, where a transmitter sends out a short microwave pulse, followed by a period when the receiver picks up the signals reflected by the water. The received signal is conveyed to the integrated evaluation system. The time travelled by the pulse corresponds with the distance travelled to and from the surface of the water.
