Battery Operated Electromagnetic Flow Meter

Developed by Zero Instrument company, ZERO100E series electromagnetic flow meter 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. That is to say, a new type of products — electromagnetic flow meter series will be developed simply by connecting a ZERO100E converter to a common electromagnetic flow meter.

The ZERO100E electromagnetic flow meter converter is equipped with a lithium battery as its standard configuration, which can work over three consecutive years. If a high-capacity battery is equipped, the continuous working time will be much longer.

The ZERO100E electromagnetic flow meter 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. Electromagnetic flow meters communicate with the base station within a closer distance (SRD mode), by use of an opened 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 ZERO100E electromagnetic flow meter 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).

• Electromagnetic flow meter converters with such a caliber need to be particularly customized.
