NBIoT wireless water level transmitter

Description :

　　NBIoT wireless water level transmitter is a lithium battery powered, wireless data remote transmission digital pressure gauge independently developed by Shaanxi Hengrui Measurement and Control. It is equipped with a high-precision pressure sensor, which can accurately display pressure in real time and has the characteristics of high stability and long-term stability.

　　This digital pressure gauge is equipped with a large-sized high-definition LCD display and a built-in MCU. With a mature GPRS/LTE/NB IoT network, the pipeline pressure on site is uploaded to the data center.

　　The NBIoT wireless water level transmitter product adopts a cast aluminum shell with good shock resistance and built-in SUS630 stainless steel diaphragm. It has good medium compatibility and can measure non corrosive media such as gas, liquid, oil, etc. that are not corrosive to stainless steel.

　　The NBIoT wireless water level transmitter product has practical functions, with adjustable reporting frequency, adjustable pressure collection frequency, and real-time pressure alarm function. Once the pressure is abnormal, alarm data will be promptly sent, and the alarm pressure value can be set. If the detection exceeds the set value twice in a row, the detection frequency will be automatically increased, and the change amount will be detected. When the change amount exceeds 10% of the total range (default, adjustable), the data will also be reported in real time.

　　In addition, the NBIoT wireless water level transmitter also has multiple pressure unit switching, error clearing, and one key wake-up functions, which are particularly suitable for unmanned and inconvenient power supply fields such as fire pipelines, fire terminals, fire pump rooms, and urban water supply that require remote monitoring.
