INTRODUCTION
The TFX-500w ultrasonic transit time flow meter measures volumetric flow of clean water in pipes 10 in. or smaller. By
clamping on the outside of the pipe, the ultrasonic meter installs without cutting or tapping the pipe.
Transit time flow meters use two transducers that clamp on to the outside of a pipe and never directly contact the fluids.
The transducers function as both ultrasonic transmitters and receivers. The flow meters operate by alternately transmitting
and receiving a frequency-modulated burst of sound energy between the two transducers. The burst is first transmitted in
the direction of fluid flow and then against fluid flow. Sound energy in a moving liquid is carried faster when it travels in the
direction of fluid flow (downstream) than it does when it travels against fluid flow (upstream). The sound’s time is accurately
measured in both directions.

OPERATION
Keypad Operation on the Home Screen
The MENU/BACK key enters menu structure.
The DOWN ARROW key toggles between flow rate, flow total, velocity and flow rate with flow total.
The RIGHT ARROW key has no function.
The ENTER key has no function.
Keypad Operation in the Menu Structure
The cursor bar highlights the submenu or parameter that will be viewed or edited. The scroll bar on the right indicates the
relative position the cursor bar is at on the list when there are more than 4 items.
• MENU/BACK returns to parent menu (up a level). If at the Main (top level) menu, returns to the Home Screen.
• DOWN ARROW scrolls the list.
• RIGHT ARROW and ENTER have the same function in the menu structure and advance to the submenu or to
read/edit a parameter.

Selecting an Option in a Parameter Selection List
The active option in the parameter list has a filled-in box on the left side. The scroll bar on the right indicates the relative
position the cursor bar is at on the list when there are more than 4 items.
• DOWN ARROW scrolls the list.
• RIGHT ARROW and ENTER have the same function in the parameter selection list. Pressing either of these buttons selects
the option and the box on the left side fills in to show the item is selected.
• MENU/BACK exits parameter editing and returns to the parent menu (up a level).
Entering a Number
The parameter name and current value is displayed in the top portion of the screen. Edit the number on the bottom right of
the screen.
• MENU/BACK exits parameter editing and returns to parent menu (up a level). The parameter remains at the value displayed
in the top portion of the screen.
• DOWN ARROW cycles through the numbers and other options.
• RIGHT ARROW moves the cursor to the right. Once it reaches the rightmost digit or a space, the cursor moves to the
leftmost digit.
• ENTER accepts the value.

INSTALLATION
Overview
Each of the installation steps that follow is explained in detail on page 10 through page 12 . The actual installation
procedures differ slightly, depending on whether the transducers are fixed or adjustable.
If the transducers are fixed, you will:
1. Install the transducers.
2. Install the transmitter.
3. Wire the transmitter.
4. Program the meter.
If the transducers are adjustable, you will:
1. Install the transmitter.
2. Wire the transmitter.
3. Set up the meter (select the optimum transmission mode, enter the site information, and enter the uid and
pipe properties).
4. Install the transducers.
5. Complete the meter programming.
Installation Considerations
Mount the transmitter in a location:
• Where little vibration exists.
• That is protected from corrosive fluids.
• That is within the transmitters ambient temperature limits: With display, –4…140° F (–20…60° C);
without display: –40…158° F (–40…70° C).
• That is out of direct sunlight. Direct sunlight may increase transmitter temperature to above the maximum limit.
Equipment Required
• Screwdrivers, wide blade and tiny blade (for securing wires to the terminal blocks)
• User manual for the transducers
• Four #8 or M4 screws, if mounting the transmitter on a wall
• Stainless steel banding straps, if mounting the transmitter on a pipe
Installing the Transducers
See the user manual for your particular transducer for installation instructions.
Installation
Page 9May 2021 TTM-UM-02537-EN-06

Installing a Meter with a Remote Transmitter and Fixed Transducers
• Locate the transmitter within the length of the transducer cables supplied or exchange the cable for one of proper length.
• See Figure 2 on page 6 for enclosure and mounting dimension details. Allow enough room for door swing, maintenance
and conduit entrances.
MPORTANTI
When routing wires to the transmitter, make sure the cables are not twisted, pinched or hanging loosely.
1. Install the xed transducers according to instructions in the transducer user manual.
2. Partially loosen the 2 enclosure captive screws on the left side of the transmitter cover. Completely loosen the 2 screws on
the right side. Grasp and lift the cover and open it to the left. The cover remains attached and the left screws act as a hinge.

3. Unscrew the wingnut from the threaded stud on the inside back of the enclosure to release the adapter plate. Set aside
the wingnut.
Figure 6: Rotatable adapter plate
4. If necessary, rotate the adapter plate by 90° to accommodate the nal orientation of the transmitter.
5. Mount the adapter plate either to a wall (with 4 customer-supplied #8 or M4 screws) or to a pipe (with mounting straps).

6. Use conduit holes where cables enter the enclosure from the bottom. Use plugs to seal any holes that are not used for
cable entry. A cable gland kit is included for inserting the transducer and power cables.
OTE:NUse NEMA 4 (IP-66) rated fittings/plugs to maintain the watertight integrity of the enclosure. Generally, the right
conduit hole (viewed from front) is used for power, the left conduit hole for transducer connections, and the center
hole is used for I/O wiring.
7. Install the wires through the gland nuts and connect the wires to the removable terminal blocks. See “Wiring the
Transmitter” on page13.
8. Wire the transducers to the transmitter.
9. Slide the meter enclosure over the threaded stud and secure it with the wingnut.
10. Plug the wired terminal blocks into the main board.
11. Reassemble the cover.
12. Set up the meter. See “Initial Meter Setup” on page16 for instructions.
