Battery Operated Electromagnetic Flow Meter

Flow meter that works without external power.

Many flow meters fail to function in remote locations due to a scarcity of electrical power. Load shading, accidental damages, or natural calamities are some of the causes of electricity failures. In such locations, a long-lasting solution is possible with a battery-operated flow meter. Manas makes Battery Operated Electromagnetic Flow Meter, which is available with an integral or remote version of the transmitter.

This meter does not require an external electric supply and can function without it as per the given specifications. This Electromagnetic Flow Meter is specifically designed where an electric supply is not available and accurate flow measurement is essential. These meters are popular where meter readings are taken periodically by local authorities for billing purposes, like Municipalities, Industrial Development corporations, etc.

Battery-operated electromagnetic flow meters are often used in remote or hard-to-reach locations where it’s difficult or costly to install a wired power source. They provide a convenient solution for applications where wiring is impractical.

The battery life can vary depending on factors such as the size of the battery, the flow rate being measured, and the frequency of measurements. It’s important to consult the manufacturer’s specifications for specific information on battery life. Manas Battery Powered electromagnetic flow meter offers a 5-year battery life.
