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 owmeter, 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
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

INSTALLATION INSTRUCTIONS

TEMPERATURE SENSOR
1. Install the meter as shown in either Figure 1 or Figure 2.
2. Mount the temperature sensor with the blue tag on the corresponding return pipe on application. The sensor with the red tag has already been installed in the meter.
3. Flush the system in the proper direction until:
• No impurities remain in the lter and pipe.
• No water leaks when pressure is added to the system.
• The humidity inside the enclosure containing the meter does not exceed 93%.
4. After ushing for a period of time; close the ball valves on either side of the meter and ush the impurities out of all lters. *3.6 V ER26500 battery may be purchased separately to power display only.
INSTALLATION REQUIREMENTS
NOTICE
measuring accuracy.
1. Ensure that there is a 10 diameter straight run of pipe upstream and a 5 diameter straight run of pipe downstream form the meter.
2. See the installation positions in Figure 3, in which A and B are the proper installation positions, while C and D are the improper positions.
3. If the meter is installed on the horizontal pipe, it must be oriented at least 45° from horizontal (see Figure 4). If the meter’s face is horizontal, then debris accumulation can increase inaccuracies (see gure 5 for correct and incorrect orientations). There is no special requirement when installing on the vertical pipe work.
4. Handle display with care. LCD display may damage with force.
Note: the meter can be installed on the return pipe or the supply pipe according to
user’s needs, but it should be selected in advance.
If the following requirements are not followed, then large air particles and impurities in the pipe could inuence the meter’s
INSTALLATION NOTES
NOTICE
CAUTION
optional battery could cause the battery to explode and cause injury to people and
damage the meter.
1. Avoid tugging on the temperature probe’s cables.
2. Ensure the water is owing in the direction indicated by the arrow on the meter’s
body.
3. If several meters are installed on the same vertical pipe work, each meter should be separated from the others to avoid pipe leakage or fallen debris that could affect the other meters’ operation.
Do not directly weld the meter on to the pipe; the extreme heat will damage the BTU meter’s internal elements.
Do not install the meter near a high temperature heat source
such as during electro gas welding. Doing so after installing an
