Ultrasonic level sensor T021 TLU

for wateranalogRS-485

Water level monitoring represents a fundamental issue when it comes to deal with the assessment of hydrological risks and the management of water resources. TLU ultrasonic hydrometric sensor is undoubtly an effective, affordable and reliable solution. It ensures excellent accuracy standards, thanks to a self-correction system 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 on the emission of an ultrasonic frequency impulse towards the surface to measure and on the subsequent reception of the reflected signal. TLU is a non-contact instrument. Furthermore, it allows to speed up and simplify the installation and maintenance steps. The sensor is supplied with power and signal cable (12m).
