Battery Powered Magnetic Water Meter

Battery Compact Magnetic flow Meters
  • Battery Compact Magnetic flow Meters

RBEFB-W Battery Powered Electromagnetic water meters are based on electromagnetic flow (EMF) technology and provide measurement of a wide flow range.

RBEFB Series battery-powered electromagnetic flowmeter converter is specifically designed for water resources and industries. It is widely used in the cases without power supply, such as: city water supply, sewage treatment, water conservancy, water administration and water resources industries. It can reach accuracy of 1.0, 0.5 or 0.2 when working with ordinary electromagnetic flowmeter sensors. The RBEFB Series battery-powered electromagnetic flow converter is generally equipped with a set of four lithium batteries typically lasting 3 - 6 years. Longer running life can be obtained if more battery set is used.

Micro-power 16-bit embedded processor was implemented to generate the sensor excitation circuit and manage the lithium battery power efficiently. It features full digital signal processing, measurement stability, high measurement accuracy and anti-interference capability. The converter supplies automatic bi-directional flow measurement, self-diagnosis and system fault alarm. The measurement data can be transmitted through the powerful GSM / GPRS remote management software system to achieve the flow data storage, analysis and other functions remotely.
