Overview:
The Micronics UF3300HM is a fixed Clamp-On Ultrasonic BTU Flow Meter designed for accurate and non-invasive measurement of both liquid flow and thermal energy in closed pipe systems. Using advanced transit-time ultrasonic technology and precision temperature sensors, the UF3300HM measures flow, temperature differential, and total energy transfer for heating and cooling applications. This permanent-mount system provides a maintenance-free alternative to inline heat meters, offering exceptional reliability and accuracy for hydronic energy monitoring, HVAC systems, and process energy management.
Built on the proven UF3300 platform, the UF3300HM features the same robust IP65 wall-mounted display enclosure that houses all electronics, keypad, sensor connections, and output terminals. The clear graphical display shows flow rate, energy, signal strength, temperature differential, and system diagnostics at a glance. Configuration is simple using the multilingual QuickStart interface, guiding users through setup in English, German, French, or Spanish.
