Product Overview
The Dwyer Series TUF Ultrasonic Energy Meter provides accurate and stable measurement of heating and cooling energy consumption in clean, compatible liquids. The TUF-1000-BN is the DN100 version, rated for a 60 m³/h permanent flow rate, making it suitable for larger HVAC systems, building energy monitoring and utility sub-metering applications.
The unit combines a flowmeter, temperature sensors and an energy calculator into one compact device, reducing the need for multiple measurement instruments. It is suitable for applications involving chillers, boilers, radiators, fan coil units and individual tenant or apartment piping where heating and cooling energy consumption needs to be monitored.
The ultrasonic measurement principle uses no moving parts, helping reduce mechanical wear and maintenance requirements compared with mechanical BTU meters. An integrated 8-digit LCD provides local readings of temperature, flow rate and energy consumption directly at the meter.
For building automation and utility management, the TUF-1000-BN provides BACnet® MSTP communication, allowing measured data to be transferred to compatible BMS and billing systems.
The meter features a plastic housing with brass and 316L stainless steel wetted parts and an IP65 enclosure rating. It supports horizontal or vertical installation, with horizontal pipe runs requiring installation at least 45° from horizontal to help prevent debris accumulation.
The DN100 model uses a GB9119 flange, DN100 PN16 connection. It operates from a 24 Vac/Vdc supply and can use a user-supplied 3.6V ER26500 lithium battery for backup.
For installations requiring Modbus communication instead of BACnet, the TUF-1000-MD uses the same DN100 flowmeter body and specifications with Modbus RTU communication.
