NB wireless level transmitter is an industrial pressure instrument that can integrate the battery power supply, ultra-low power consumption, wireless communication and pressure detection. Based on NB-Iot/4G coverage, this product can realize the online detection for the pressure point in a wide area. Combined with the application of the big data platform Web, the remote configuration of instrument sampling interval, transmitting interval and alarm threshold etc. can be realized. The instrument is designed with IP67 protection, which can be applied to outdoor places. The installation is simple and fast, and the data can be uploaded as long as the machine is started up; the field data can be easily obtained through PC or mobile phone.
