Series TUF Ultrasonic Energy Meter with BACnet Communication
Specifications - Installation and Operating Instructions
Bulletin F-TUF-B
The
Series TUF Ultrasonic Energy Meter
is a highly accurate and stable energy
meter that utilizes ultrasonic technology to measure heating and cooling energy
consumption. The Series TUF is a compact meter with a flowmeter and energy
calculator in one, making it great for installation on chillers and boilers.
FEATURES/BENEFITS
• Lower maintenance costs with local parameter display and no moving parts
• Serial communication output allows for easy transfer of data
• Flow and temperature monitor in one unit eliminates the need for multiple units
APPLICATIONS
• Heat metering
• Utilities billing
• Tenant billing
• Monitoring of water heating or cooling: radiators, fan coils
