Battery powered electromagnetic flow meter converter

Featured Applications

The power supply options for lithium battery powered electromagnetic flow meters include:

  • First power supply option: Built-in 3.6V battery
  • Second power supply option: 3.6V + 220VAC dual power supply (85VAC~265VAC) (split type only)
  • Third power supply option: 3.6V + 24VDC dual power supply (9VDC~32VDC)

Battery powered electromagnetic flow meters can be widely used in locations without a power supply, such as urban water supply, water conservancy irrigation, and sewage treatment industries.

  • Specifically designed for applications where power supply is inconvenient or unstable.
  • Measurement of water flow in water intake and supply networks: Can be installed in any location.
  • Agricultural irrigation: Saves water and improves irrigation efficiency.

Wireless Communication Network Setup

The battery powered converters can utilize a base station-based wireless communication network system. A communication base station is established in the regional center, with a coverage radius of 1000 meters. Each electromagnetic converter communicates with the base station via short-range communication (SRD mode), using the 928 MHz open frequency band (US standard). The base station communicates with the management computer via a GPRS or CDMA cellular network.

Alternatively, the battery powered converters can also communicate directly with the management computer via a GPRS or CDMA cellular network (see the communication manual for details on GPRS communication).
