Introduction:
DeleeTech's sensors and instruments based on the Internet of things can be quickly connected to the cloud to realize the synchronous monitoring of the long pipe trailer and the gas in the pipe by computer and mobile phone. They are suitable for hydrogen, compressed natural gas CNG, oxygen, nitrogen, argon, carbon dioxide, nitrous oxide and other gas media. Multiple parameters can be remotely transmitted to the cloud platform to realize the monitoring of the gas pressure, temperature, gas concentration , etc. Real time monitoring of gas concentration and other data, timely alarm, online security management and operation analysis of cloud, and cloud layout of asset Internet of things are realized. Effectively increased the pressure vessel monitoring efforts, improve the safety of the equipment. The design of the electronic fence function of cloud platform is helpful to the dispatching and operation of long-distance vehicles, reduces the input cost and improves the productivity.
It is recommended to install the following two IOT instruments: Temperature pressure composite transmitter (4G + GPS / BD) DPT8851 and Temperature pressure composite transmitter (4G) DPT8851.
