CONNECTIONS:
POWER INPUT: The standard model requires AC power input between 100 to 240 VAC 50/60Hz
10VA. No adjustments are necessary for voltages within this range. Connect L (Live) N (Neutral) and
AC Ground.
Optional DC input model requires 9-32 VDC/10 Watts. Connect to + and - terminals.
Optional Thermostat and Heater modules are available rated for specifically 115 VAC or specifically
230 VAC.
IMPORTANT NOTE: To comply with electrical safety standards, AC power input and relay connection
wires must have conduit entry to the instrument enclosure. Installation requires a switch, overcurrent
fuse or circuit breaker in the building (in close proximity to the equipment) that is marked as the
disconnect switch.
Risk of electric shock. Loosen cover screw to access connections. Only qualified personnel
should access connections.
Note: Use of instrumentation over 40°C ambient requires special field wiring.
Note: User replaceable fuse is 2 Amp 250V (T2AL250V), located on the power supply.

TYPICAL SENSOR INSTALLATION
Page 23
TTFM 6.1 Transit Time Flow Meter
Pipe Preparation and Bracket Mounting
Prepare an area 2" wide by 4" long (50mm x 100mm) for each sensor bonding by removing loose paint,
scale and rust. The objective of site preparation is to eliminate any discontinuity between the sensor and
the pipe wall, which would prevent acoustical coupling.
A Sensor Mounting Kit is supplied with each Greyline flow meter. It includes recommended coupling
compound and a stainless steel mounting bracket with adjustable pipe straps. Use the Alignment Bar
(included) to align sensor brackets for V and W mode mounting.
IMPORTANT: The SE16-B transit-time transducers have arrows on the top of them. These should face
each other at installation.
Page 24
TTFM 6.1 Transit Time Flow Meter
SENSOR COUPLING
For permanent or temporary bonding, the following are recommended:
a) Super Lube® (supplied)
Additional supply: order Greyline Option CC-SL30 or your local home improvement store.
b) Water-based sonic compound: Order Greyline Option CC30
c) Electrocardiograph gel
d) Petroleum gel (Vaseline)
The above are arranged in their order of preferred application. Option d is only good for temporary
bonding at room temperature. DO NOT USE: Silicon RTV caulking compound (silicon rubber).
Use the pipe clamp and rail (supplied) as illustrated on previous page. Apply
Super Lube® to the colored face of the sensor. A bead, similar to toothpaste on
a toothbrush, is ideal. Do not overtighten (crush the sensor).
The sensor must be fixed securely to the pipe with coupling material
between the sensor face and the pipe. Sensor installation with
excessive coupling compound can result in gaps or voids in the
coupling and cause errors or loss of signal. Insufficient coupling
compound will create similar conditions.
Over time temporary coupling compounds (e.g. Petroleum Gel) may gradually sag away from the sensor
resulting in reduced signal strength and finally complete loss of signal. Warm temperatures, moisture
and vibration will accelerate this process. Super Lube® as supplied with the TTFM 6.1 (and available
from Greyline Instruments or home improvement stores) is recommended for permanent installations.
Transducer Installation in Wet Locations
The TTFM 6.1 Transit Time Flowmeter transducers are
rated for accidental submersion up to 10 psi (0.75 bar). The
flowmeter will continue to operate and measure flow
accurately during periods of submergence. Plastic seal
jackets on the cables must be filled with coupling compound
to provide additional moisture protection for the BNC cable
connectors.
Page 25
TTFM 6.1 Transit Time Flow Meter
SENSOR MOUNTING LOCATION
The position of the sensor is one of the most important considerations for accurate flow measurement.
The same location guidelines apply to Transit Time as most other flow meter technologies.
VERTICAL OR HORIZONTAL PIPE - Vertical pipe
runs are acceptable, and the transducers can be
mounted in any orientation around the pipe.
Downward flow should be avoided in case the pipe
becomes partially filled or aerated. On Horizontal
pipes and liquids with high concentrations of gas or
solids, the sensors should be mounted on the side (1 to
5 o’clock positions) to avoid concentrations of gas at
the top of the pipe, or solids at the bottom.
STRAIGHT RUN REQUIREMENTS – For best
results, the transducers must be installed on a straight
run of pipe, free of bends, tees, valves, transitions,
insertion probes and obstructions of any kind. For
most installations, ten straight unobstructed pipe
diameters upstream and five diameters
downstream of the transducers is the minimum
recommended distance for proper operation.
Additional considerations are outlined below.
• Do not, if possible, install the transducers downstream from a throttling valve, a mixing tank, the
discharge of a positive displacement pump or any other equipment that could possibly aerate the
liquid. The best location will be as free as possible from flow disturbances, vibration, sources of heat,
noise, or radiated energy.
• Avoid mounting the transducers on a section of pipe with any external scale. Remove all scale, rust,
loose paint, etc., from the location prior to mounting the transducers.
• Do not mount the transducers on a surface aberration (pipe seam, etc.).
• Do not mount transducers from different ultrasonic flow meters on the same pipe.
• Do not run the transducer triaxial cables in common bundles with cables from other instrumentation.
You can run these cables through a common conduit ONLY if they originate at the same flow meter.
• Never mount transducers under water.
IMPORTANT NOTE: In some cases, longer straight runs may be necessary where the transducers are
placed downstream from devices which cause unusual flow profile disruptions or swirl. For example:
modulating valves, or two elbows in close proximity and out of plane.

TTFM 6.1 Transit Time Flow Meter
SEPARATION DISTANCE (Sensor Spacing Distance)
Separation distance is automatically calculated by the TTFM 6.1 based on parameters entered in the
Setup menu. Sens Space is parameter where this distance is given, and it is located in the Setup
menu. Document this value for the following transducer installation procedure.
2 OR 4 CROSS INSTALLATION OVERVIEW - TMK-B1 Kit
1. Prep the pipe per instructions on page 23, and mind the installation location requirements on
page 25. Clean the location where the sensor is to be mounted on the opposite side of the pipe
after we’ve marked where it will be installed. Picture below shows a very clean ductile iron pipe
which did not require much cleaning. The outside paint is very well bonded and did not need to
be removed:
2. Install the stainless steel mounting brackets on the pipe. Position them at approximately the
correct separation distance. Exact measurement is not required at this time. Tip: Use a 5/16” nut
driver to tighten the hose clamps.
Procedure continued on the next page…

2 OR 4 CROSS INSTALLATION OVERVIEW - TMK-B1 Kit (Cont.)
3. Use alignment bar to ensure the brackets are parallel. Completion of steps 2 & 3 is shown below.
4. Mark the position of the permanent bracket on the pipe. This is the bracket that will not be
adjusted, and will be used as the reference for the separation distance and alignment. It is your
choice which bracket is permanent. With a marker, mark the bracket position by placing the
mark directly in front of the stainless side-rail.
Page 28
TTFM 6.1 Transit Time Flow Meter
2 OR 4 CROSS INSTALLATION OVERVIEW - TMK-B1 Kit (Cont.)
5. Measure the separation distance from the mark you created in step 4, and create a new mark on
the pipe at the separation distance. It may be useful to mark your Greyline tape measure
(included with every meter) at the separation distance point before marking the pipe. The marked
pipe is shown below.
6. Move the non-permanent bracket to position at the mark you created at step 5, and tighten it
completely. Apply coupling compound to the transducers, and install them in the brackets.
Tips for installing transducers:
a. Be sure the red knob on the brackets are loosened completely
b. Put the transducer into the bracket by ensuring the bottom of the transducer and the
couplant does not touch the pipe as you slide it in. (Hover)
c. With the transducer hovering, tighten the red knob on the bracket until thight. The
transducer will be level with the surface of the pipe, and no grease will have smeared off.

SEPARATION DISTANCE (Sensor Spacing Distance)
Separation distance is automatically calculated by the TTFM 6.1 based on parameters entered in the
Setup menu. Sens Space is parameter where this distance is given, and it is located in the Setup
menu. Document this value for the following transducer installation procedure.
1 CROSS INSTALLATION OVERVIEW - TMK-B1 Kit
1. Prep the pipe per instructions on page 23, and mind the installation location requirements on
page 25. Clean the location where the sensor is to be mounted on the opposite side of the pipe
after we’ve marked where it will be installed. Picture below shows a very clean ductile iron pipe
which did not require much cleaning. The outside paint is very well bonded and did not need to
be removed:
2. Install the stainless steel mounting brackets on the pipe. Position them at approximately the
correct separation distance. Exact measurement is not required at this time. Tip: Use a 5/16” nut
driver to tighten the hose clamps.

3. Use alignment bar to ensure the brackets are parallel. Completion of steps 2 & 3 is shown below.
4. Mark the position of the permanent bracket on the pipe. This is the bracket that will not be
adjusted, and will be used as the reference for the separation distance and alignment. It is your
choice which bracket is permanent. With a marker, mark the bracket position by placing the
mark directly in front of the stainless side-rail. Additionally, create a center line mark:

5. Measure the separation distance from the mark you created in step 4, and create a new mark on
the pipe at the separation distance. It may be useful to mark your Greyline tape measure
(included with every meter) at the separation distance point before marking the pipe:.
6. Using the tape measure which ships with every TTFM, wrap it around the pipe, keep it taut, and
use a marker to mark anywhere the tape overlaps:
Page 33

7. Lay the tape measure flat, and use a secondary tape measure to measure the distance between
overlap marks, and create a new mark at the center point:
8. Position the marked tape measure back on the pipe, with the overlap mark at the current position
of the bracket which is to be rotated. While holding it in this position, mark the pipe where the
center line on the tape measure is located (you may need two people for this step):

Page 48
TTFM 6.1 Transit Time Flow Meter
ENCLOSURE INSTALLATION
Locate the enclosure within 25 ft (7.6 m) of the sensors (up to 100 ft - 30 m optional). The enclosure can
be wall mounted with the four mounting screws (included) or panel mounted with Option PM Panel
Mount kit from Greyline Instruments.
Avoid mounting the enclosure in direct sunlight to protect the electronics from damage due to
overheating and condensate. In high humidity atmospheres, or where temperatures fall below freezing,
Option TH Enclosure Heater and Thermostat is recommended. IMPORTANT: Seal conduit entries to
prevent moisture from entering enclosure.
NEMA4X (IP66) WITH CLEAR COVER
1. Open hinged enclosure cover.
2. Insert #12 screws (supplied) through the four enclosure mounting holes to
secure the enclosure to the wall or mounting stand.
Additional conduit holes can be cut in the bottom of the enclosure when
required. Use a hole saw or Greenlee-type hole cutter to cut the required
holes.
IMPORTANT: DO NOT make conduit/wiring entries into the top or sides
of the enclosure.
Note: This non-metallic enclosure does not automatically provide grounding between conduit
connections. Grounding must be provided as part of the installation. Ground in accordance with the
requirements of the National Electrical Code. System grounding is provided by connecting grounding
wires from all conduit entries to the steel mounting plate or another point which provides continuity.

SENSOR CABLE & TRANSDUCER RESISTANCE TEST
Unplug the green sensor terminal from the Transit Time board with the sensor wires still connected and
the BNC end of the cable is connected to the transducer. With a multimeter, perform resistance checks
for each set of wires. One single loose terminal may cause false readings.
Test across shield and core of each wire: TDR1 and TDR2. Resistance should be around 10K ohms for
any cable length. High readings indicate an open circuit and low readings indicate a short or partial short
in the sensor cable connections or transducer.
Note: The TTFM 6.1 will automatically detect connectivity to the sensors. Confirm that TTFM 6.1
indicates “Sensor Good” in the messages menu if your resistance measured is
approximately 10K Ohms.

COMMON QUESTIONS AND ANSWERS
The pipe vibrates. Will it affect the flow meter?
Common vibration frequencies are far lower than the sonic frequencies used by the Greyline flow meter,
and will not normally affect accuracy or performance. However, applications where very weak Transit
Time signal is present (when sensitivity is adjusted to maximum and signal strength is low), accuracy
may be affected by pipe vibration, or the flow meter may show readings under no-flow conditions.
Attempt to relocate the sensor on a pipe section where vibration is reduced, or arrange pipe mounting
brackets to reduce vibration at the sensor mounting location.
The flow meter must be installed in a high noise environment. Will this affect operation?
Greyline flow meters are designed to discriminate between environmental noise and the Transit Time
signal. High noise environments may affect the flow meter’s performance where low signal strength
and/or low flow velocities are being measured. Relocate the sensor in a quieter environment if possible.
Will pipe corrosion affect accuracy of the flow meter?
Yes. Rust, loose paint etc. must be removed from the outside of the pipe to provide a clean mounting
position when installing a Transit Time sensor. Severe corrosion/oxidation on the inside of the pipe may
prevent the Transit Time signal from penetrating into the flow. If the pipe cannot be cleaned, a spool
piece (PVC recommended) should be installed for sensor mounting.
What effect do pipe liners have on the flow meter?
The air gap between loose insertion liners and the pipe wall prevent the Transit Time signal from
entering the flow. Better results can be expected with bonded liners such as cement, epoxy or tar,
however an on site test is recommended to determine if the application is suitable for a Transit Time
flow meter.
Why is Transit Time recommended for clean liquids?
The Transit Time sensor transmits sound across the flow stream in order to measure the time it takes to
arrive at the other sensor, and therefore requires a fluid medium that is relatively transparent to the
acoustic signal. The Transit Time system will not function when there is high volume of solids or
aeration. As a guideline, Greyline Transit Time flow meters are recommended for clean liquids with
solids or bubbles content less than 2% by volume.
Can the sensor be submerged in water?
Yes, for short periods of time or by accident, but it is not recommended for continuous operation. The
sensor is constructed to withstand submersion to 10 psi (0.7 Bar) without damage provided the
protective rubber boot is filled with Super Lube®.
Page 53
TTFM 6.1 Transit Time Flow Meter
What is the purpose of the Signal Strength Display?
The primary function of the signal strength display is to assist as a feedback when mounting sensors.
Signal Strength can also be a useful diagnostics tool when troubleshooting problems with an installation.
A signal strength less than 100% may indicate a problem with the installation or other issues such as a
mis-programmed pipe size, pipe material, fluid type or temperature, or wrong transducer spacing. A
signal strength less than 100% may also simply indicate a lot of aeration, or deteriorated pipe.
Consideration should be made to use a 1 cross installation in such a case.
Can I change the length of the sensor cable?
Yes. The Greyline Transit Time design allow cable lengths up to 100 ft (30 m) or extension up to 250 ft
with extra cable and JB2X optional junction box. Replacement cable of different length may be installed
in rigid or flexible conduit for mechanical protection. Use only Greyline shielded triaxial cable.
Does the TTFM 6.1 require periodic recalibration?
TTFM 6.1 calibration does not drift over time. The solid state sensor has no moving parts to wear and
affect calibration. All Greyline timing/counting circuits use crystal-controlled frequency references to
eliminate any drift in the processing circuitry.
ISO 9000 or similar quality management systems may require periodic and verifiable recalibration of
flow meters. TTFM 6.1 Flow Meters may be returned to Greyline for factory calibration and issue of a
new NIST traceable certificate. Refer to the ‘Product Return Procedure’ section of this manual for return
instructions.
