Battery-Powered Electromagnetic Flowmeter With Low Power Consumption And Remote Data Transmission

This is a special type of electromagnetic flowmeter designed for situations where no external power supply is available. It is powered by a built-in high-performance lithium battery and features an ultra-low power consumption design, enabling continuous operation for several years (typically 3 to 6 years or even longer). It is an ideal solution for remote and field flow monitoring in municipal water supply, agricultural irrigation, energy metering, and other fields.

1. True passive operation: No external power supply is required, and the installation location is unrestricted. It is particularly suitable for outdoor areas without municipal power, where cable laying is difficult or costly.
2. Easy installation and low cost: As there is no need to consider power supply lines, installation is very fast and simple, significantly reducing wiring costs and engineering complexity.
3. High precision and reliability: Advanced excitation technology and signal processing algorithms are adopted, ensuring low power consumption while achieving measurement accuracy of ±0.5%, ±0.2%, or even higher.
4. Data recording and storage: Usually equipped with large-capacity storage, it can be used as a flow data logger, capable of long-term recording of instantaneous flow, cumulative flow, forward and reverse flow, daily and monthly flow, and other historical data.
5. Powerful communication functions:
   • On-site meter reading: Supports wireless methods such as infrared, Bluetooth, or NFC. Staff can use handheld devices to read data on-site at close range without opening the cover or connecting wires.
   • Remote transmission: This is one of its core functions. It typically integrates wireless communication modules such as NB-IoT, LoRa, GPRS, or 4G, enabling data to be uploaded to cloud platforms or monitoring centers at regular intervals or in real-time, facilitating remote monitoring.

• Urban and rural water supply network district metering (DMA): Installed in valve wells on urban streets to monitor regional flow and leakage.
• Agricultural water metering: Installed on channels or pipes in farmlands to charge and manage water resources.
• Energy management systems: Measure the cold/hot water consumption of central air conditioning systems, installed in the pipe wells of buildings.
• Groundwater monitoring: Monitor the extraction volume of underground water resources.
• Power-free point monitoring in industrial processes: Monitor the flow at remote or power-free process points within factories.
• Environmental monitoring: Monitor the flow of wastewater or clean water at enterprise discharge outlets or river sections.

Battery-powered electromagnetic flowmeters are outstanding representatives of modern Internet of Things technology in the field of flow measurement. They have traded off "real-time continuity" for ultimate convenience and flexibility, solving the long-standing core difficulty of flow monitoring in power-free environments.

In summary, if you need to reliably measure the flow of conductive liquids in a place without power supply, and conduct long-term data recording and remote transmission, the battery-powered electromagnetic flowmeter is almost the only and best choice.
