IoT IC Card Gas Turbine Flowmeter Overview HWQZ Series IoT IC Card Gas Turbine Flowmeter is a metering device integrated the gas turbine flowmeter (sensor), IC card flow compensation controller and control valve. The gas turbine flowmeter measures the gas flow rate and converts it to the flow rate and total flow rate under standard conditions, and takes IC card as the medium. For gas consumption, a new trade settlement method of “purchasing gas first and then using it” is adopted. It is embedded with a NB-IoT/GPRS communication module to upload the temperature, pressure, transient standard condition, transient working condition, total gas consumption, remaining gas volume/amount, valve status, battery level and other data of the IC card flowmeter to the cloud server, and achieve wireless remote monitoring, meter reading, analysis and management of the IC card flowmeter through the server terminal. It integrates the computer software, network communication, smart card application, secret key security and other technical fields, and is an ideal prepaid flow measuring product for the urban smart gas. Features I. IoT correction controller Integrate flow compensation & calculation, IC card operation and valve control. Compact in structure and free of signal transmission error, with high reliability. The embedded NB-IoT/GPRS module can form a variety of wireless meter reading systems. Power supply by built-in batteries can achieve a limited number of wireless data transmission, which is easy to use. Besides, the external power supply is also available for online data transmission in real time.
