ASIONIC 400

Product Description

ASIONIC 400 Battery Operated Ultrasonic Flow Meter is a full-bore, inline flow measurement solution using advanced transit time ultrasonic technology for accurate and reliable liquid flow measurement. The meter offers obstruction-free design with zero pressure drop, ensuring maintenance-free operation and long-term stability. Designed for municipal and industrial water applications, it supports pipe sizes from 15 NB to 600 NB and delivers accuracy up to ±0.5% of measured value. ASIONIC 400 features local LCD indication for flow rate and totalized flow, with automatic display shut-off to extend battery life. The battery or solar-powered operation provides a service life of up to 5–10 years, making it ideal for remote installations. With IP67 weatherproof and CMRI flameproof certification, along with optional GSM, GPRS, and RF communication, it ensures dependable performance in harsh field conditions.
