Irrigation hydrometer IDU2 series

The Hydroval2 IDU2 is a double-flanged water meter engineered to minimise pressure loss via an innovative valve with a second‑generation elliptical membrane. It integrates an ultrasonic flow meter with pulse output to deliver precise instantaneous flow and total volume measurement, notably at low flow rates, while ensuring minimal pressure drop, reduced maintenance and extended service life.

Overview

• European patent protected model.
• Equipped with UWM ultrasonic flow meter providing pulse (impulse) output for instantaneous flow and totaliser reading.
• Power supply: lithium battery with an estimated service life of about 10 years.
• Ultrasonic measurement avoids moving parts in the flow, reducing wear and maintenance requirements.
• Main hydraulic components: second‑generation elliptical membrane, ultrasonic meter and motorised ball valve on the hydraulic circuit to optimise distribution and longevity.
