Water level monitoring is the basis of the assessment of hydrological risks and the management of the water resource. TLU ultrasonic hydrometric sensor represents an effective, affordable and reliable solution. It ensures excellent performance for what concerns accuracy, thanks to a system of self-correction of the hydrometric measurement. Indeed, by means of an integrated temperature sensor, it can easily take into account the variation of the speed of sound as a function of the density of the air. The measurement principle is based above the emission of an ultrasonic frequency pulse in the direction of the surface of interest and on the subsequent reception of the reflected wave. The TLU is a non-contact instrument. Furthermore, it allows to speed up and simplify the installation and maintenance steps. The sensor is supplied complete with power and signal cable (12m). Main feautures • Non-contact sensor • Self-correction of the measurement for compensation of air temperature • Equipped with sun screen • Compact and affordable • Easy to instal
