Electromagnetic flow meters

Full-pipe flow for STP inlets, ETP discharge and process lines

Electromagnetic flow meters use Faraday's law to measure velocity in conductive liquids. They are the standard for STP inlet and outlet metering, ETP discharge and industrial pipelines where full-pipe flow and high reliability are needed.

SYZE integrates them end to end with CPCB / PHED dashboards, telemetry, solar-ready RTUs and OEM sensors, with reverse-flow alerts, local data backup and remote firmware updates.

How the meter measures

Electromagnetic flow meter A flanged electromagnetic flow sensor in a full pipe, with its transmitter on top sending readings over RS485 Modbus to the data logger. Inside the sensor, coils create a magnetic field B across the pipe; liquid flowing at velocity v induces a voltage U between two electrodes, proportional to the velocity: U = k × B × v × D. Flow RS485 Modbus Data logger Transmitter Sensor, flanged into the line Fitted where the pipe always runs full: in a low section or a rising line, never at a high point. Inside the sensor B v U electrode U = k × B × v × D
Faraday's law: liquid moving through the sensor's magnetic field induces a voltage proportional to its velocity.
