151 MFM – B

A battery-operated electromagnetic flow meter is a versatile, maintenance-free instrument used for measuring the flow of conductive liquids. Utilizing Faraday’s Law of Electromagnetic Induction, it generates a magnetic field and measures the voltage induced by the fluid’s flow, ensuring accurate, obstruction-free measurement. Powered by long-life lithium batteries, it is ideal for remote or mobile installations. Key specifications include accuracy of ±0.5%, conductivity of measured liquid is ≥50µS/cm, IP68 protection for remote sensor, and data logging with GSM / GPRS / RS485 communication output. Typical applications include water distribution, irrigation systems, and wastewater management.
