The old saying “you can’t manage what you don’t measure” has never been more relevant. With today’s HVAC systems accounting for over 50 percent of a building’s total energy usage, it is important to know where and when that energy is being consumed. Incorrect usage data negatively impacts a building’s operating costs and can significantly reduce efficiency.
Siemens is addressing this issue by helping to create intelligent buildings that manage energy usage effectively and in real-time. One of the ways we’re accomplishing this is by outfitting our flow measurement technology with digital communication protocols like Modbus and BACnet. These protocols allow building management systems (BMS) to retrieve ALL diagnostic data from the installed flow meters, providing invaluable data on process conditions and overall system performance.
Non-intrusive and easy to install, clamp-on ultrasonic flow meters are ideal for chilled water and hot water applications. These meters do more than just measure flow – they provide key diagnostics that offer a “window into the process,” or what we like to call Green Building Intelligence™ (GBI). Clamp-on meters can indicate cavitation, aeration, liquid changes/quality, and much more, all from outside the pipe. And, many SITRANS F US clamp-on ultrasonic flow meters from Siemens now come equipped with the capability for both Modbus and BACnet communication, ensuring you maximum control over the efficiency of any building.
