Profec Ultrasonic Water Meter DN15 – Accurate, MID-Approved Flow Measurement for Pool and Irrigation Systems
This Profec ultrasonic water meter offers highly accurate, non-mechanical flow measurement for domestic and light commercial water circuits. Operating on the proven ultrasonic transit-time principle, it contains no moving parts, eliminating wear-related drift and reducing maintenance intervals significantly. The compact brass body with 3/4 inch male thread connections fits directly into standard pipe assemblies without adapters, making it an efficient choice for pool plant rooms, greenhouse irrigation headers, and building water sub-metering installations.
The meter carries full MID (Measuring Instruments Directive) approval under certificate RO-2275-16379, accuracy Class 2, making it legally suitable for billing and custody-transfer applications across EU member states. The white ABS housing is rated IP68, meaning the electronics and display remain protected during temporary submersion — an important feature for outdoor or below-ground meter-pit installations. The backlit LCD shows cumulative volume in m³, and the RS485 output with 24 V DC supply enables direct integration into building management systems, irrigation controllers, and SCADA platforms.

Compatibiliteit
The DN15 3/4 inch male thread connections are compatible with standard 3/4 inch female BSP fittings used in copper, brass, stainless-steel, and CPVC pipe systems. The 165 mm installation length matches the standard meter-replacement dimension common in European residential and light-commercial metering pits. The 24 V DC / RS485 interface is compatible with Modbus RTU-based controllers, including common irrigation management units and pool automation systems that accept RS485 input. Not suitable for hot-water systems above 50 °C or for compressed-air or gas measurement.

In detail
- No moving parts — zero mechanical wear, long-term measurement stability without recalibration
- MID Class 2 certified (RO-2275-16379) — legally valid for billing and sub-metering in the EU
- IP68 housing — safe for outdoor meter pits and below-ground installations with risk of temporary flooding
- RS485 / 24 V DC output enables plug-and-play integration with Modbus RTU irrigation and BMS controllers
- 10-year battery life reduces service visits; production and expiry date stamped on the unit for easy audit
- One flow direction only — must be installed with correct orientation (inlet/outlet marked on body)
- Requires 24 V DC external power supply for RS485 communication; no pulse output variant in this configuration
- Maximum water temperature limited to 50 °C — not suitable for hot-water or heating circuits
