Adopts explosion-proof shell structure and passes Ex d IIB T4 explosion-proof certification, which can be used safely in Ex IIB T4 grade flammable and explosive environments. Equipped with dual power supply mode to ensure continuous operation, the backup battery can continue to work for ≥45 days in case of power failure. Supports remote data transmission and abnormal alarm, and can be connected to enterprise security systems and explosion-proof supervision platforms, eliminating potential safety hazards caused by manual meter reading and improving the safety and accuracy of flammable and explosive media measurement.
Nominal diameter range is DN25~DN50, maximum working pressure is 1.6MPa. The size of DN25 model is 320mm×280mm×180mm, and the total weight is about 8kg. The protection grade is IP67. The communication protocol is 4G/LoRaWAN. The explosion-proof grade is Ex d IIB T4. The power supply mode is AC85~265V + ER34615 backup battery. The data sampling interval can be adjusted to 10 minutes. The interface type is flange connection (PN16), and the operating temperature range is -20~70℃.
Suitable for scenarios with flammable and explosive media such as gas stations, chemical plants, oil depots and liquefied petroleum gas stations. It can be used to measure the flow of flammable and explosive liquids, replacing traditional mechanical explosion-proof water meters to realize remote management and data monitoring, improving operation safety and measurement accuracy, and complying with national explosion-proof safety standards.
