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. Product Advantages - 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.
- 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.
- 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.
- 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.
- 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.
Application scenarios - 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. | Feature | Battery-powered Electromagnetic Flowmeter | Traditional Mains-powered Electromagnetic Flowmeter |
|---|
| Power Supply | Internal lithium battery | External 220V AC or 24V DC | | Installation Flexibility | High, no position restrictions | Limited by power cords | | Measurement Method | Intermittent measurement | Continuous measurement | | Output Signal | Wireless communication (NB-IoT/LoRa, etc.) | 4-20mA, pulse, wired communication | | Core Application | Remote, field, and passive monitoring | Continuous control and monitoring in industrial processes | | Maintenance Focus | Battery life | Stability of power supply, line maintenance |
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. |
