Product Details

KEFD Pro DN40/50 Electromagnetic Water Meter

Precision comes from customization, and KEFD Pro is dedicated to managing service-oriented trade measurement. Its lightweight appearance, compact design, and support for various installation environments.
The rectangular guide pipe design can meet the requirements of ultra-low flow velocity measurement and zero straight pipe installation.
Support full frequency IoT transmission methods, making the measurement of every drop of water truly visible.

High R value: The R value can reach up to 500 and further reduce Q1, truly achieving drip metering.
Extremely low starting flow rate: 5mm/s, solving the problem of small flow measurement in traditional mechanical meters and minimizing measurement losses.
High reliability: With a straight tube design and no mechanical rotating parts, its metrological performance will not change with increasing age or cumulative quantity.
Strong anti-interference: The entire machine and components have passed strict EMC testing to ensure stable operation under complex environmental conditions.
Direct data transmission: Different from traditional mechanical water meters, it does not require electromechanical conversion and can directly read the instantaneous and cumulative flow of memory through RS-485 or GPRS, ensuring data accuracy.
High detection frequency: By using new technology, the normal detection frequency can be increased by 2-3 times without affecting accuracy, greatly reducing measurement errors under intermittent flow at night and accurately measuring every drop of water.
Long term measurement accuracy: Due to the principle of electromagnetic flow measurement and the absence of movable parts, long-term measurement will not cause wear and tear. Even if the weekly inspection is not carried out according to 2 years, the measurement accuracy can be guaranteed, avoiding the negative deviation caused by wear and tear of mechanical water meters and causing water loss to the water company.
Anti disassembly design: The whole machine adopts a hidden screw design and is equipped with lead seals to prevent structural damage.
IP68 design: The entire machine meets the performance requirements of IP68, ensuring stable operation in various complex environmental conditions.
Support normal meter calibration: Support water meter calibration under normal measurement conditions.
Hidden integrated pressure measurement (optional): The structural design integrates the pressure sensor and flow sensor into one, with no exposed leads to the pressure probe, preventing damage to the pressure line and aviation plug caused by improper construction and improving product stability.
Flat design: specially developed and designed for residential environments, the overall height of the product is smaller than conventional products, solving the problem of insufficient depth of some wells that cannot be installed.
Long lifespan of lithium batteries: Designed with lower power consumption, the theoretical lifespan of lithium batteries is ≥ 12 years, ensuring a usage of ≥ 6 years.
Zero straight pipe section: can meet the measurement accuracy requirements under UODO conditions.
6-year warranty: We promise a 6-year warranty period and offer a complimentary 6-year communication fee (with industrial grade patch IoT network card as standard at the factory).
Report in case of changes: Based on the low-power design of the product, data is collected and stored every 5 minutes by default, and the stored data is packaged and reported to the cloud platform server every 6 hours through 4G or NB IoT networks. When an alarm event occurs, the reporting logic will be immediately activated to report the alarm information to the cloud platform server, buying valuable time for troubleshooting. Alarm events include but are not limited to the following alarms: low battery alarm, instantaneous flow upper and lower limits, instantaneous pressure upper and lower limits, air traffic control alarm, and excitation alarm.
