1 INTENDED USE
The radar sensor SEBAPuls is solely used for non-contact measurement of water level in rivers,
channels, dams, lakes or tidal areas.
Consider the technical specifications in chapter 8 when using the device.
Solely the use in accordance with the instructions described in this user manual is an intended use.
Any other use is not an intended use of this device.
2 PRODUCT DESCRIPTION
The radar sensor SEBAPULS is a high accuracy measuring device measuring the surface water level
without direct contact. Therefore the radar measurement is unaffected by mudding, drifting
materials, weed, sewage and brackish or saline water etc.
There is no influence in the measurement accuracy caused by air humidity (fog) or air temperature
fluctuations. Further advantages implementing this radar sensor are the low energy consumption,
the short measuring cycle and the short mounting distance.
The measuring principle, the so called pulse procedure, sends a short microwave impulse to the
water surface. Subsequently the transmitter has a short time lag. Within this time lag, it receives the
reflected impulse from the water surface and transmits it to the integrated evaluation system. The
run time of the impulses corresponds directly to the distance of the actual surface water level.
