Ultrasonic Ultrasonic is a contact-less technology for level measurement applications. The sensor emits short ultrasonic pulses which are reflected from the product surface and captured by the same sensor. The distance to the product surface is obtained with the exact measurement of the time between pulse emission and echo reception, and consequently the level measurement. An internal digital temperature sensor corrects the measurement as a function of air temperature. Our ultrasonic level transmitters are suitable for measurements of liquids and granules, for distance up to 10 m. Concentrated...

Radar The instrument antenna sends tight electromagnetics pulses on base band 26 GHz (C-band). These pulses are irradiated and then reflected, from the product surface to be measured and received back by the same antenna. A method of time elongation, allows the assessment of the time of flight which, by its nature, is particularly short, to be able to calculate with accurancy the distance and hence the level of the product to be measured. Dust, vapors, high temperatures and pressures are well tolerated and allow the use of units in critical conditions. An advanced computerized system by “envelope...
