  Description

The Electronet ELMAG-TX22 is a microcontroller-based, two-wire, full-bore electromagnetic flow transmitter designed for accurate measurement of conductive liquids and slurries in closed pipelines.

Built using Pulsed DC excitation technology, the ELMAG-TX22 provides high stability, excellent accuracy, and long-term reliability. The device generates a magnetic field inside the flow tube—based on Faraday’s Law of Electromagnetic Induction—and the voltage induced by the flowing liquid is converted into a precise 4–20 mA output (with optional HART).

Its obstruction-free design ensures zero pressure loss, minimal maintenance, and long operational life. The rugged construction, multiple material options, and advanced signal processing make it suitable for a wide range of industrial applications.
