Description
MEGA-W801 series battery powered electromagnetic converters are battery powered, capable of being used together with common electromagnetic flow meters, with the flow rate measurement accuracy up to 0.5 level and 0.2 level.
The W801 battery powered electromagnetic converter is equipped with a lithium battery as its standard configuration, which can work consecutively three to six years. If a high-capacity battery is equipped, the continuous working time will be much longer.
The W801 battery powered electromagnetic converter may use a base-station type radio communication network system, with the communication base station built in the central area, and coverage radius designed as 1000M. Battery powered electromagnetic converter communicate with the base station within a closer distance (SRD mode), by use of an opened power frequency range — 928MHZ （American standard）. The base station, via GPRS or CDMA mobile communication network, realizes data communication with the supervisory computer. In addition, the W801 battery powered electromagnetic converter may, via GPRS or CDMA mobile communication network, directly realize data communication with the supervisory computer. (Please see communication instructions for further information about GPRS communication).
