Invasive Flowmeter

The Flexim FLUXUS Energy Thermal Energy Meter is a state-of-the-art, non-intrusive ultrasonic flow and thermal energy meter designed for accurate and reliable measurement of liquids in HVAC systems, district energy plants, and industrial cooling/heating applications. It combines ultrasonic clamp-on flow measurement with integrated temperature sensing to provide comprehensive energy metering without any process interruption. This meter is ideal for energy efficiency optimization, continuous commissioning, energy audits, and submetering in utilities monitoring. Thanks to its clamp-on design, it can be retrofitted easily on existing pipes without downtime or invasive pipe modifications.

Non-intrusive clamp-on ultrasonic flow measurement for liquids, eliminating the need for pipe cutting or modifications.
Integrated temperature sensors for accurate thermal energy calculation conforming to EN 1434 standards.
High accuracy and repeatability, capable of measuring very low flow velocities (down to 0.02 ft/s).
Maintenance-free operation with patented permanent coupling pads requiring no grease.
Wide application versatility: chiller plants, heating plants, HVAC systems, district energy, industrial cooling, and building optimization.
Supports continuous data logging with built-in storage (up to 2 years at 10-min intervals).
Communication options include analog outputs, RS485, Modbus RTU, Modbus TCP, BACnet IP, and more.
Calibration services available, supported by field experts and in-house calibration laboratories.
Suitable for LEED, Energy Star, and other energy certification requirements.
Robust design with permanent sensors suitable for extreme temperatures, up to 380°F (193°C).
