Application range

FC-RF701 wireless water and gas heat meter module is a wireless meter reading module tailored by our company to realize the wireless remote meter reading function of water and gas heat meter. It realizes the pulse metering and historical data storage of water and gas meter. Billing, wireless meter reading and other functions. Ultra-low power reception is achieved by using the timed sleep wake-up detection method. It integrates high-performance wireless transceiver circuit, small size, low power consumption, and with our specially designed handheld machine, it can realize wireless remote meter reading of data such as water and gas heat meter.

The FC-RF701 wireless water and gas heat meter module can work in three working modes: water meter, gas meter and heat meter. In the water meter or gas meter mode, only a 3.6V lithium sub-battery, two reed switches, and a motor can be connected externally to realize all the electronic parts of the water meter or gas meter, plus the mechanical equipment of the water meter or the gas meter. In part, it constitutes a complete water meter or gas meter with pulse acquisition function, billing function, and wireless meter reading function. In the heat meter mode, it is only necessary to externally connect a heat meter with RS485 interface, RS232 interface or TTL level interface to realize wireless remote meter reading of heat meter data. In the above three modes, the FC-RF701 module can use the handheld device developed by our company to realize long-distance wireless meter reading. Communication between the FC-RF701 and the handheld is fully compliant with the CJ/T188-2004 protocol.
