ASIONIC 400-4 Multipath Ultrasonic Flow Meter is a high-performance, full-bore Multipath insertion flow measurement solution engineered with advanced four-path chordal transit-time ultrasonic technology for superior accuracy, linearity, and repeatability. It delivers exceptional measurement accuracy of ±0.2% of the measured value, making it suitable for critical flow applications. Designed for clean conductive and non-conductive liquids, the obstruction-less construction ensures negligible pressure drop and maintenance-free operation. The meter is wet calibrated at an ISO 17025 / NABL accredited laboratory to ensure reliable and traceable performance. ASIONIC 400-4 supports line sizes from 100 NB to 2000 NB and features empty pipe and partial flow indication for improved process reliability. Optional pressure and temperature measurement, along with IoT-enabled communication options such as MODBUS, GSM, and GPRS, enable seamless system integration. With robust IP67/IP68 weatherproof and CMRI flameproof certified electronics, it is ideal for municipal water, industrial water, cooling tower, and water treatment applications..
Configure the transmitter and electronics based on application, environment, and compliance requirements.
