Ultrasonic water meter DN25 (1") ARAD Sonata – modern and precise water meter This water meter can be used in various areas, such as water consumption measurement in industrial plants or in water treatment systems. Precise consumption measurement with modern ultrasonic technology The ARAD Sonata ultrasonic water meter in the DN25 (1 inch) version is designed for precise measurement of water consumption in larger pipelines. The ultrasonic technology enables wear-free measurement without moving parts, ensuring long-term stable and reliable operation. Even at very low flow rates, the meter delivers accurate results. At the same time, the robust design ensures a long service life and low-maintenance operation. The two integrated pulse outputs can be individually configured and allow flexible integration into existing control, monitoring, or evaluation systems. They support both forward and reverse measurements as well as simultaneous output of both measurements. Why use the ARAD Sonata water meter? This version is particularly suitable for applications with higher flow rates or larger pipe dimensions. Thanks to precise ultrasonic measurement and flexible signal output, water consumption can be reliably recorded and further processed. Your advantages with the ARAD Sonata Ultrasonic measurement without mechanical components High measurement accuracy even at low flow rates Two freely configurable pulse outputs Suitable for DN25 / 1" pipelines Low maintenance and durable due to robust design Possible application areas of the water meter Water consumption measurement in industrial plants Process and cooling water monitoring Water treatment systems Building and system monitoring Technical data Nominal size: DN 25 (1 inch) Measurement principle: Ultrasonic (without moving parts) Pulse outputs: 2 freely configurable Pulse resolution: e.g. 1 / 10 / 100 / 1000 liters adjustable Measurement direction: forward, reverse, or combined Application: Measurement of water consumption in pipelines Frequently asked questions How accurately does the ARAD Sonata measure my water consumption? The meter uses ultrasonic technology and measures flow very precisely – even with very small volumes of water. Do I need to service or clean the water meter regularly? No. As it contains no moving parts, the meter requires little maintenance and operates reliably for many years. Can I retrofit the meter into my existing pipework? In most cases, yes. The meter fits into standard installations and can often be replaced without any problems. Does the meter work even with very low water consumption? Yes, it detects even the smallest water flows and measures them reliably. How long does the battery in the meter last? The built-in battery is designed for a long service life and usually lasts for many years. Can I read the meter digitally or connect it to a wireless system? Many models support digital or wireless reading, allowing consumption data to be recorded conveniently.

Ultrasonic water meter ARAD Sonata 3/4 inch (DN 20) – modern and precise The measurement with this water meter is reliable even at very low flow rates, allowing even the smallest water consumption to be accurately recorded. Water meter with modern ultrasonic technology for precise consumption measurement The ARAD Sonata ultrasonic water meter is a modern and precise water meter for reliable measurement of water consumption. Thanks to ultrasonic technology, the device operates completely without moving parts, enabling particularly long-lasting and low-maintenance use. Why use this water meter? The ARAD Sonata is particularly suitable when precise measurement, low maintenance, and long-term reliability are required. Due to the absence of moving parts, there is minimal wear and no measurement errors caused by mechanical influences. The dual pulse output also enables flexible integration into existing systems for evaluation, control, or monitoring. Your advantages at a glance Very high measurement accuracy even at low flow rates Low maintenance due to the absence of mechanical components Two configurable pulse outputs Long service life and robust design Possible application areas Water consumption measurement in buildings Submetering Industrial and process systems Monitoring of water distribution Applications with high accuracy requirements Technical data Nominal size: DN20 (3/4 inch) Ultrasonic measurement without mechanical components Two freely configurable pulse outputs: forward, reverse, combined Pulse resolution: individually adjustable (e.g. 1 / 10 / 100 / 1000 liters) Protection class: IP68 for demanding environments Service life: up to approx. 12 years Operating temperature: approx. -20 °C to +60 °C Frequently asked questions How accurately does the ARAD Sonata measure my water consumption?
