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

display enables easy reading of the meter’s recorded values; including temperature, ow-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

INSTALLATION INSTRUCTIONS

BALL

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

1. If meter is not in use during freezing conditions, drain all water from the connecting pipe. Low temperatures will cause the water to freeze in the pipe and damage the

meter.

2. This device is intended to be used with clean water. While dirty water will not damage the meter, it will cause errors in the reading.

3. A lter should be mounted near the meter and cleaned regularly.

4. If the heat exchanging system is operating normally, but the instantaneous ow-rate of the heat meter reduces signicantly, then there is too much dirt in the lter. This will narrow the pipe and reduce the ow. Cleaning the lter will x the problem.

5. To protect the meter and avoid damage from harsh conditions, it is recommended

that the meter be encased in an enclosure.

DISPLAY

1. Switching Between Information Holding down the button for > 1s will switch the sections from curren information ▲, to monthly information ▲▲, and then to other information ▲▲▲. Once in the desired section, pressing the key will switch the information shown for the given

section.

2. Display Units Energy is displayed in kW•h, power is displayed in kW, ow volume is displayed as

, and ow-rate is displayed in m3/h.

3. Display Details

a. “Monthly Reading Date” is displayed as “Pd= XX”, in which XX is the end date of the current month’s energy summation. The factory default value is 31, meaning that the monthly recording period ends at midnight on the 31st day of the month. At this time the current month’s cumulated energy will be stored and the system will begin to record the next month’s energy.

b. The meter can store and display the recordings from the past 18 months.

c. The units for “Sum of Working Time” (hours) is displayed as h.

d. “Software and Protocol Editions” are displayed as “UEr.X.X X.X”. The rst X.X is the software edition code and the second X.X is the communication protocol edition

code.

e. “Leaving-factory serial number” is the meter’s identication number, which is the same as the one in the external label. This serial number is a unique number set by the factory; it is also the secondary address in M-BUS system.

f. Battery Voltage displays “UCC=X.XX” (the default unit is Volts). When the battery’s voltage capacity is lower than 2.9±0.1 V, “ ” will appear on the display. This symbol will not appear if no battery is installed.

g. If there are any unresolved errors, the start date will display as normal but the end date will display “00-00-00”, and then the error message will be displayed.
