ALSONIC Plastic DN15-DN50

Versatile ultrasonic flow meter available in DN15-DN50 sizes, delivering ±2% accuracy across measurement ranges from 9 L/h to 60,000 L/h at pressures up to 10 bar and temperatures -20°C to 90°C. This compact solution features integrated temperature sensing, optional pressure measurement, resistance to various types of deposits, including magnetite, gas bubble detection, and glycol concentration monitoring with automatic flow compensation. Equipped with multiple communication interfaces (Pulse, 0-5V analog, Modbus RTU) and robust PPS construction ensuring >12 years lifetime, it's ideal for heat pump systems, hydronic heating and cooling, district heating networks, HVAC applications, heat metering, and others.
