QUICK-START OPERATING INSTRUCTIONS This manual contains detailed operating instructions for all aspects of the TFXL instrument. The following condensed instructions are provided to assist the operator in getting the instrument started up and running as quickly as possible. This pertains to basic operation only. If specific instrument features are to be used or if the installer is unfamiliar with this type of instrument, refer to the appropriate section in the manual for complete details.
pipe, choose a flow meter mounting location within approximately 45-degrees of the side of the pipe. See Figure Q.2. Locate the flow meter so that the pipe will be completely full of liquid when flow is occurring in the pipe. Avoid mounting on vertical pipes where the flow is moving in a downward direction. 3) Apply a single ½” (12 mm) bead of acoustic couplant grease to the upstream transducer and secure it to the pipe with a mounting strap.
the sound crosses the pipe once. The selection of how transducers are mounted on opposite sides of the pipe and method is based on pipe and liquid characteristics which both have an effect on how much signal is generated. The flow meter operates by alternately transmitting and receiving a frequency modulated burst of sound energy between the two transducers and measuring the time interval that it takes for sound to travel between the two transducers.
Locate the transmitter within the length of transducer cable that was supplied with the TFXL system. If this is not possible, it is recommended that the cable be exchanged for one that is of proper length. Both transducer cables must be of the same length. NOTE: The transducer cable carries low level, high frequency signals. In general, it is not recommended to add additional cable to the cable supplied with the DTTN, DTTH, DTTS or DTTC transducers.
Wiring methods and practices are to be made in accordance with the NEC - National Electrical Code® - and/or other local ordinances that may be in effect. Consult the local electrical inspector for information regarding wiring regulations. TRANSDUCER CONNECTIONS When making connections to the field wiring terminals inside the flow meter, strip back the wire insulation approximately 0.25 inch (6 mm). Stripping back too little may cause the terminals to clamp on the insulation and not make good contact.
NOTE: The transducer cable carries low level, high frequency signals. In general, it is not recommended to add additional length to the cable supplied with the transducers. If additional cable is required, contact the factory to arrange an exchange for a transducer with the appropriate length of cable. Cables 100 to 990 feet (30 to 300 meters) are available with RG59 75 Ohm coaxial cable. If additional cable is added, ensure that it is the same type as utilized on the transducer.

iterative process. Table 2.2 contains recommended mounting configurations for common applications. These recommended configurations may need to be modified for specific applications if such things as aeration, suspended solids, out of round piping or poor piping conditions are present. Use of the TFXL diagnostics in determining the optimum transducer mounting is covered later in this section.
the transducers should be mounted 180 radial degrees from one another and at least 45 degrees from the top-deadcenter and bottom-dead-center of the pipe. See Figure 2.2. Also see Z-Mount Transducer Installation. On vertical pipes the orientation is not critical. ½” (12 mm) TOP OF PIPE 45° FIGURE 2.
NOTE: Mounting of high temperature transducers is similar to mounting the DTTN transducers. High temperature installations require acoustic couplant that is rated not to “flow” at the temperature that will be present on the pipe surface. DTTS/DTTC SMALL PIPE TRANSDUCER AND INTEGRAL MOUNT INSTALLATION The small pipe transducers are designed for specific pipe outside diameters.

Measure from the end of the crease (directly across the pipe from the first transducer location) the dimension derived in Step 2, Transducer Spacing. Mark this location on the pipe.
calculated transducer spacing. See Figure 2.13. Using firm hand pressure, slowly move the transducer both towards and away from the upstream transducer while observing signal strength. Clamp the transducer at the position where the highest signal strength is observed. Signal strength of between 5 and 98 is acceptable. The factory default signal strength setting is 5, however there are many application specific conditions that may prevent the signal strength from attaining this level.

For the TFXL this relationship is described by the following equation. The 60,000 relates to measurement units in volume/min. Measurement units in seconds, hours or days would require a different numerator. K factor 60,000 Full Scale Units EQUATION 3.
2) Double-click on the ULTRALINK icon. The first screen is the “RUN” mode screen (see Figure 4.2), which contains real-time information regarding flow rate, totals, signal strength, communications status, and the flow meter’s serial number. The COMM indicator in the lower righthand corner indicates that the serial connection is active. If the COMM box contains a red ERROR, click on the Communications button on the Menu bar and select Initialize.

will be in the Flow Rate Units. For unidirectional measurements, set Max Flow to the highest (positive) flow rate expected in the piping system. For bidirectional measurements, set Max Flow to the highest (positive) flow rate expected in the piping system. Low Flow Cutoff is provided to allow very low flow rates (that can be present when pumps are off and valves are closed) to be displayed as zero flow. Typical values that should be entered are between 1.0% and 5.
are examined by the Bad Data Rejection filter. The value is entered as a percentage of actual flow rate. For example, if the average flow rate is 100 GPM and the Flow Filter Hysteresis is set to 5%, a filter window of 95-105 GPM is established. Successive flow measurements that are measured within that window are recorded and averaged in accordance with the Flow Filter Damping setting. Flow readings outside of the window are held up in accordance with the Bad Data Rejection filter.
Flow at 4 mA / 0 Hz = -100.0 Flow at 20 mA / 1,000 Hz = 100.0 Calibration (Page 1 of 3) - Zero Flow If the meter were a TFXL, this setting would also set the span for the frequency output. At -100 GPM, the output frequency would be 0 Hz. At the maximum flow of 100 GPM, the output frequency would be 1,000 Hz, and in this instance a flow of zero would be represented by an output frequency of 500 Hz. 1. Make sure flow is at zero. 2. Wait for flow to stabilize. 3. Press to calibrate the zero offset.

K-FACTORS EXPLAINED The K-factor (with regards to flow) is the number of pulses that must be accumulated to equal a particular volume of fluid. You can think of each pulse as representing a small fraction of the totalizing unit. An example might be a K-factor of 1000 (pulses per gallon). This means that if you were counting pulses, when the count total reached 1000, you would have accumulated 1 Gallon of liquid. Using the same reasoning each individual pulse represents an accumulation of 1/1000 of a gallon.
The calculation is a little more complex if velocity is used because you first must convert the velocity into a volumetric flow rate to be able to compute a K-factor. To convert a velocity into a volumetric flow, the velocity measurement and an accurate measurement of the inside diameter of the pipe must be known. Also needed is the fact that 1 US gallon of liquid is equal to 231 cubic inches. Example 3: Known values are: Velocity Inside Diameter of Pipe = = 4.3 ft/sec 3.
