Water Sub-Meter

Ultrasonic Water and Thermal BTU Meters

Ultrasonic water and thermal BTU meters are precision instruments used to measure water flow and energy consumption in hydronic heating and cooling systems. These meters use high-frequency sound waves to calculate flow rate and energy usage with no moving parts, ensuring long-term accuracy, low maintenance, and superior reliability in both residential and commercial applications.

Ultrasonic water meters are ideal for non-invasive, tamper-resistant flow measurement, while ultrasonic BTU meters provide accurate readings of thermal energy by measuring the temperature differential between supply and return lines. These meters are commonly used in chilled water systems, hot water loops, district energy networks, and multi-tenant buildings for energy billing and submetering.
