SLS3200 Wireless GFSK/Lora/4G/IOT liquid level transmitter

SLS3200 wireless level transmitter adopts micro-power wireless communication mode, no wiring is required, installation is faster, safer and more convenient. It has built-in high- precision pressure sensor, which can accurately display the pressure in real time, and has the characteristics of high stability and long-term stability.

SLS3200 wireless level transmitter adopts micro-power wireless communication mode, no wiring is required, installation is faster, safer and more convenient. It has built-in high- precision pressure sensor, which can accurately display the pressure in real time, and has the characteristics of high stability and long-term stability.This type of digital level gauge is equipped with large-scale HD LCD display and built-in MCU. With mature GFSK/Lora/4G/IOT network, the on-site pipeline pressure is uploaded to the data center .

Or, it is can be matching with wireless switching device, which can convert many wireless pressure signals into MODBUS standard signals and transmit them through Ethernet or serial port.
