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.

STATUS
Press from the Main Display to view Status of the measurement. Press to
return to the Main Display.
Velocity Displays flow velocity in ft/s or m/s, selected in the
Units/Mode menu.
Flow Displays flow rate in units selected in the Units/Mode
menu. A list of flow rate units is provided in the
Units/Mode section of the manual.
Min Flow Displays a read-only value for the minimum flow
cutoff, in units which match the Flow selection.
Measured flow rates below the Min Flow will result in
the displayed flow rate on the LCD display to be 0.0.
This parameter is used to suppress electrical noise at
zero flow conditions, and it is typically set to the flow
rate equivalent of 0.1 ft/sec in the programmed pipe
size. The Min Flow can be adjusted in the Calibration
menu.
Signal
Strength Displays magnitude of signal being received by the
ultrasonic sensors. 100% is the ideal signal strength.
Signal strengths less than 100% could indicate poor
pipe conditions (corrosion), highly aerated water, or
programmed setup parameters which don’t closely
match field conditions. Consideration should be made
to use 1-cross installation method in such cases, if not
already using it.

Exp. SOS Displays the expected fluid speed of sound
measurement, in units that match the Velocity. The
expected speed of sound is based on the pipe, fluid,
and temperature selection in the Setup menu.
Meas. SOS Displays the measured fluid speed of sound, in units
that match Exp. SOS. The meter calculates this value
based on the time it takes for the signal to arrive from
one transducer to another. Large differences between
expected and measured speed of sound (> 10%)
typically indicate an error in the setup of the
instrument. Verify the following are correct in the
Setup menu and with the physical installation of the

Older pipes are often degraded or scaled on the inside.
These conditions can hinder the ability to receive a strong
signal when Crossings = 4 or 2. We suggest starting with
Crossings = 2 or 1, respectively, in these cases.
Zero Tare Used to calibrate zero-flow measured by the TTFM 6.1 in
process. Flow in the pipe should be confirmed as 0 before
enabling, or significant errors in flow accuracy could occur.
Set Calibration/Damping to 0%, and under no flow
conditions and with a full pipe, select Yes to force readings
to zero.

Sens pace After sensor, angle, fluid, and pipe material are defined, this
displays the calculated sensor spacing. Also called the
separation distance. The sensors will be set to this
dimension when installed on the pipe, as described later in
this manual.
Velocity Displays the measured velocity after the sensors have been
connected at the specified separation distance.
Signal
Strength Displays magnitude of signal being received by the
ultrasonic sensor. Should be 100% under ideal operating
conditions. Signal strengths less than 100% do not indicate
that the meter is not reliable, however, the meter may be
more susceptible to complete signal loss should process
conditions like entrapped air worsen. When signal strength
is less than 100%, consideration should be made to using 1-
cross mounting method if this is not the current mounting
mode.

CALIBRATION
Press or to position curser at Calibration menu, and to enter. Use or
to position cursor before each menu item and to enter. When settings are
completed press to store and again to return to the Main Menu.
Mode Displays the Mode which was selected in the Units/Mode
menu. This is read-only.
20mA Press then or to change the numbers and decimal
point position. Use this menu to set the corresponding flow
rate that will be represented by 20mA analog output. If
maximum flow is unknown, enter an estimated flow rate and
observe actual flow to determine the correct maximum
value. Any velocity or flow rate up to +40 ft/sec (12.0 m/sec)
may be selected.
4mA Press then or to set the flow rate corresponding to
4mA analog output. This setting may be left at zero or can
be raised to any value less than the 20mA setting, or
lowered to any velocity or corresponding flow rate down to
-40 ft/sec (-12 m/sec).
LOS Time Use LOS Time to suppress intermittent loss of signal.
Example: systems with high concentrations of undissolved
gasses will cause fluctuations in signal strength when the
gasses move past the ultrasonic signal. If a complete loss of
signal is experienced, the TTFM 6.1 will hold the last valid
reading for the duration of the LOS Time. If the signal
strength returns before the LOS Time is expired, because the
ultrasonic signal is no longer being impeded, the meter will
return to normal operation automatically. If signal strength
does not return after the LOS Time has expired, then the
meter will report zero flow on the LCD display and outputs
and produce a Low Signal alarm. Default LOS Time is 30
seconds, and the value can be set between 0 and 99
seconds.
Min Flow Flow rates below this setting will be displayed as zero flow.
Default flow rate is ~ 0.1 ft/sec for the pipe size
programmed in the Setup menu.

CALIBRATION (cont.)
Damping
Mode Choose between OFF, FIR (Default), or LOW PASS.
When measured flows are outside the Window of the
running average, the FIR filter will reduce the damping
average so that a fast response can be made to the sudden
change in flow rate.
The LOW PASS filter will ignore measured flow rates outside
the Window, while holding the running average, until there
are enough data points outside the Window to cause a step-
response to the new measured value.
While measured flows are within the Window of the running
average, both the FIR and LOW PASS filter behave the same.
Percent Higher percentages increase the number of measurements
which are averaged together to produce a stable flow
reading. Higher percentages also increase the time it takes
for the meter to make a step-response to the measured flow
rate outside the Window in the LOW PASS Mode.
Window Defines the Window around the running average, in units of
Velocity set in the Units/Mode menu. Measurements made
inside the Window are added to the running average, and
measurements outside the Window effect the response of
the meter as described in the Mode section.
