Sierra’s InnovaSonic® 207i Liquid Ultrasonic Flow Meter now supports BACnet digital communication protocol for easy building automation and control.

With BACnet, Modbus RTU and Thermal Energy BTU capability, the 207i offers facilities mangers the complete water flow energy management solution. 

BACnet is a communications protocol for Building Automation and Control (BAC) networks that is governed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), SSPC 135, ANSI, and ISO 16484-5 standard protocol.

BACnet Digital Protocol is designed specifically for building and automation control networks and is quickly becoming the industry standard for large facility and manufacturing automation, HVAC, and chiller manufacturers.

“The combination of Sierra’s 207i Ultrasonic Liquid Flow Meter with Thermal Energy BTU capability and BACnet digital communication protocol make the 207i the perfect plug and play water meter for the building automation sector,” said Scott Rouse, Vice-President of Product.

The 207i calculates thermal energy/BTU by determining the amount of heat transferred between the cold and hot flow legs of a heating or cooling process, providing end users with the high-quality flow energy data required to manage energy costs.

The 207i ensures accuracy of +/-0.5% of reading from 0.16 to 40ft/s (0.05 to 12 m/s) even if liquid density changes as the temperature of a flowing liquid moves up and down over time. The 207i is the first ultrasonic flow meter to have dynamic real-time density compensation to assure the best possible accuracy.
