With skyrocketing energy costs, there has never been a better time to invest in the precise flow measurement required to maximize your heating and cooling system efficiency, meet regulations, and bring down costs. Designed, built and calibrated by Sierra for non-intrusive liquid flow metering, and optimized for thermal energy / BTU measurement, the Innova-Sonic® 207i transit-time ultrasonic flow meter is the ideal turnkey solution for building and district metering, and submetering. The Flow Engine Behind it All At the heart of every 207i is advanced digital signal processing to enhance ultrasonic...

With the InnovaSonic 207i's clamp-on sensors, there's no pipe cutting or expensive plumbing. The 207i features a large backlit display and dualfunction keypad with audible feedback. With its visual sensor spacing tool on the display (see photo in center), slightly move the sensors together or apart to position the indicator line between the “goal posts” and assure optimal signal strength. Easily connect the 207i to your building management system with Modbus or BACnet communications. With its robust stainless steel enclosure, permanently fasten the transducers to make it a hardened installation,...

WaterLoop World Class Calibration Designed by Sierra and located at our metrology headquarters in Monterey, California, Sierra's Water-Loop™ is among the world's most accurate liquid/gas calibration facilities. Rated at +/- 0.2% of reading, all calibrations follow the guidelines of ISO 17025 and are directly traceable to national standards such as NIST (US National Institute of Standards and Technology). Fully automated, once flow application data is programmed, calibration automation software manages all aspects of flow calibration testing. This results in high-speed time-aligned data acquisition and...
