Wireless pressure (liquid level) meter used in urban IoT fire protection

      The firefighting Internet of Things means that through the Internet of Things information sensing and communication technology, the equipment and facilities in the traditional firefighting system are linked through the socialized firefighting supervision and management and the firefighting information required by the firefighting and rescue elements of the public security organ firefighting organization, to build high-sensitivity firefighting basic environment. Real-time, dynamic, interactive, and integrated firefighting information collection, transmission, and processing can comprehensively promote and improve the level of social firefighting supervision and management implemented by the government and related agencies, and significantly enhance the firefighting and rescue activities of public security organ firefighting agencies, which also enhance their commanding, scheduling, decision-making and handling capabilities.

The Internet of Things fire remote monitoring system can remotely monitor indoor fire hydrant status, fire hydrant pipe pressure, automatic sprinkler system water pressure, high level fire tank and fire pool water level, and fire water supply pipeline valve opening and closing by using sensor technology and Internet of things communication technology. Status and other situations; and through the PC computer, mobile phone APP system, dynamic monitoring, three-dimensional display of the fire safety status of the networked unit. It provides early warning of places with hidden fire safety hazards through multiple channels, comprehensively improve the fire safety management level of the social unit and fire supervision and law enforcement efficacy.

NB-IOT wireless intelligent instrument is specially designed for monitoring fire water system. NB-IOT wireless intelligent instrument is composed of wireless pressure, temperature gauge, water immersion, wireless liquid level and water quality gauge. The instrument is installed in each fire water system, which can monitor the pressure, liquid level, temperature, TDS (water quality), gas and other data in real time. Data can be transferred to the IoT cloud platform (currently supports several major IoT platforms such as telecommunications platforms, mobile onenet platforms, Huawei platforms, TLINK platforms). And the data can be viewed on computers and mobile phones. When the data monitoring is abnormal, the intelligent instrument will immediately send out alarm information through WeChat, SMS, phone, etc., which can be used by firefighters to make specific fire response. In addition, the smart meter has a built-in lithium battery for power supply which can work for more than five years and solves the trouble and worry of frequently changing the battery.

The pressure and liquid level sensors of wireless smart meters have their own historical data storage function and support historical data breakpoint continuous transfer function. If the network interruption occurs under special circumstances, the smart meter will immediately send historical data to the cloud platform server after the network is restored to avoid data loss and other phenomena. The smart meter itself also comes with saved data and can be exported with USB at any time, in this conditions it supported reliable and safe data storage on both sides.

      In addition, wireless intelligent instruments can meet the requirements of harsh working conditions such as moisture resistance, waterproof, explosion-proof, dust-proof, and anti-soaking. The pressure sensor has high temperature stability and time stability,  a 200% FS overload pressure design and corrosion resistance and impact resistance 316L isolation diaphragm which can be in direct contact with most media.
