Prosonic Flow Ultrasonic Flow Meters (Endress+Hauser)

Prosonic Flow is Endress+Hauser’s advanced range of ultrasonic flow meters designed for non-intrusive clamp‑on measurement and high‑accuracy inline flow monitoring. Using transit‑time or Doppler ultrasonic technology, Prosonic Flow meters provide reliable measurement for water, wastewater, energy monitoring, industrial utilities and process liquids — without cutting pipes or interrupting production.

What Prosonic Flow Meters Are Designed For

Prosonic Flow uses ultrasonic wave propagation to measure flow velocity and calculate volumetric flow. This makes it ideal for:

• Water and wastewater flow measurement
• Energy and thermal energy monitoring (BTU metering)
• Industrial utilities and cooling water
• Process liquids and chemicals
• Temporary or portable flow measurement
• Applications where pipe cutting is not possible

Clamp‑on ultrasonic meters are especially valuable for retrofit installations and large pipelines.
