The Series TUF Tennant Ultrasonic BTU Flowmeter is a MID/EN1434 approved
highly accurate and stable energy meter. It utilizes ultrasonic technology to measure
heating and cooling energy consumption. The Series TUF incorporates a flowmeter,
temperature meter, and a calculator into a single, compact unit. The size and lack of
moving parts means the Series TUF requires minimal maintenance. The 8-digit LED
display enables easy reading of the meter's recorded values; including temperature,
flow-rate, energy consumption, etc. These features make it ideal for installation on
chillers, boilers, and individual apartment piping. With the optional couplings it is
capable of being used with either NPT or BSPT pipe sizes. It is the perfect meter for
tenant billing applications.
FEATURES
• 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
