The SEBA-Electric Contact Meter type KLL is a portable, reliable instrument for measuring the water level and total depth in
boreholes, wells, reservoirs etc.
For the measurement the probe is lowered to the water level. When touching the level, a sensor effects the illumination of a signal lamp. On request, an additional acoustic signal will be released by a buzzer. The depth is shown on the cable in metres and centimetres. If the measurement of water level and total depth is desired, an additional ground sensor (see accessories) is adaptable. When the sensor is touching the bottom, the signal lamp is switched off. In case of very small diameter tubes, instrumentes with a probe of 10 mm dia. (not suitable for ground-sensor and sensor-cap) are available.
Principle of function
When the probe is touching the water-level there is a conductive connection between the tip of the probe and the sensorbody. Thereby a circuit of the lamp and the buzzer will be closed.
