The InnovaSonic 207i transit-time ultrasonic liquid flowmeter from Sierra Instruments has thermal energy/BTU capability for superior flow measurement. Designed for nonintrusive liquid flowmetering, and optimized for thermal energy/BTU measurement, the unit is the ideal turnkey solution for building and district metering and submetering. It calculates thermal energy/BTU by determining the amount of heat transferred between the cold and hot flow legs of a heating or cooling process. This provides end users with the high-quality flow energy data required to manage energy costs. 800/866-0200; www.sierrainstruments.com.
