ST505 Ultrasonic Energy Meter

The ST505 is a professional ultrasonic energy meter designed for accurate monitoring of flow, heating energy and cooling energy in commercial and industrial installations. Combining non-invasive clamp-on ultrasonic flow measurement with temperature monitoring, the system provides valuable insight into thermal energy consumption without requiring modifications to existing pipework.

Designed for HVAC systems, district energy networks, cooling circuits and building management applications, the ST505 helps facility owners and operators understand how energy is consumed throughout their systems. Accurate energy data supports improved efficiency, reduced operating costs and better-informed investment decisions.

The clamp-on transducers are mounted externally on the pipe, eliminating the need for pipe cutting, process shutdowns or intrusive installation work. The system can be installed on existing infrastructure while operations remain fully active, making it ideal for both permanent monitoring systems and temporary energy audits.

When equipped with PT100 temperature sensors, the ST505 continuously measures supply and return temperatures in combination with flow rate data, providing real-time thermal energy calculations for heating and cooling applications.
