ELMAG TX-22

Product Description

ELMAG TX-22 Two-Wire Electromagnetic Flow Meter is a microcontroller-based, full-bore flow measurement solution designed for conductive liquids and slurries in closed pipelines. Operating on Faraday’s Law with Pulsed DC excitation, it delivers accurate and stable flow measurement with minimal power consumption through a 2-wire 4–20 mA loop-powered system. The obstruction-less design ensures zero pressure loss and maintenance-free operation, making it a reliable alternative to mechanical flow meters. ELMAG TX-22 supports pipe sizes from 15 NB to 300 NB and offers accuracy up to ±0.5% of measured value. Features such as empty pipe detection, local LCD indication, HART compatibility, and rugged IP67/IP68 protection make it ideal for water, wastewater, and industrial process applications. Its simple, cost-effective construction ensures long-term performance in demanding field conditions.
