Frinso Battery-Based Electromagnetic Flowmeter (EMF)
Smart. Self-Powered. Always Connected.
The next-generation instrument for accurate flow measurement where power is scarce. With internal lithium battery and IoT-ready telemetry, it keeps remote assets visible and compliant.
Product Overview
Frinso’s Battery-Operated EMF combines precision magnetic sensing with low-power digital electronics to deliver long-term flow measurement without external power or wiring.
Internal lithium battery powers continuous metering in off-grid sites.
Stable electromagnetic sensing even at low velocities.
Real-time data to Frinso Cloud via GSM/GPRS/Lora/RS-485.
IP68 submersible sensor + converter for chambers & pits.
No moving parts; magnetic keypad configuration without opening.
