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
INSTRUCTIONS FOR ORDERING
• Choose 1 ultrasonic energy meter model
• Choose 2 pipe fitting models given the appropriate fitting size (for DN15 to DN40
only)*
Example: TUF-150-MD, Fitting Size: A, select pipe fitting Model WM-ACC-C01 or
WM-ACC-C11.
