Product catalog summary

Description
The TLU Ultrasonic Level Sensor is designed for water level monitoring, crucial for hydrological risk assessment and water resource management. It offers high accuracy through a self-correction system that compensates for air temperature variations using an integrated temperature sensor. The sensor operates on the principle of emitting an ultrasonic frequency impulse and receiving the reflected signal, making it a non-contact instrument that simplifies installation and maintenance.

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...
