IUD57L ultrasonic level meter has a beautiful appearance, stability performance; explore proof design and good measurement function. Isolated power supply by industrial instruments, all of the output, input lines with lightning protection, overvoltage, over current protection circuit functions.

With LoRaWAN® module, it transmits the pressure via gateway to networks server and application server. User can monitor the status remotely. It is optional for different frequency, such as 470Mhz (China), 868Mhz (Europe), 915Mhz(USA), 923Mhz (Australia). As it is with algorithm of low power consumption, the internal battery can work for more than 1 years for one charge (With different parameter, 3 years lifetime is realized).
