1. Overview
RBEFB-LS battery powered electromagnetic flow
meter 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 Class 1 &2,
when working with ordinary electromagnetic flow meter
sensors.
The RBEFB-LS 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.

Software feature
The system can be measured for each point of the water to conduct inquiries, statistics, charts
and analysis of the curve or in the form displayed so that users can convenience of the
measuring point of the water management situation.
When the measuring point of water at the scene or unusual situation Meter battery power is low,
the system may issue a warning signal, the alarm signal can be sent directly to the user's
designated officer on the phone.
The system can be configured for different levels of a number of operators, data management
at different levels to play, and the realization of the user's local area network to share data.
The introduction of the system of data backup, SIM card fees, and other statistics more humane
management.
