KEYPAD SYSTEM

The MantaRay uses a menu system for general use and configuration. Arrows show the four directions to navigate
the menus. Pressing a corresponding keypad arrow will move to the next item in the direction shown. Move the
cursor (underline) under numerals and increase or decrease numerals with the  and  keys.

To store calibration values permanently (even through power interruptions), press .

BATTERY

- A built-in rechargeable NiMH battery supplies power for approximately 40 hours continuous operation when
fully charged. Your battery life may vary depending on factors like temperature, battery age, and backlight level.

- Display brightness is adjustable to conserve power. Press the “Back-Light” button to disable the backlight
completely.

- The MantaRay will switch off automatically when the battery is fully discharged.

- Full charge requires approximately 6 to 9 hours charging. The charge rate will be fastest between 0 and 90%, and
then it will slow down as it approaches 100% so that it is not over-charged.

- Sleep mode extends battery life for long-term data logging (30 days for 5 minute logging).

CHARGING BATTERY

A 16.5V AC-DC power module is supplied for battery charging and continuous use. The charger connects to the
faceplate of the MantaRay or to the exterior of the break-out box. Charge requires 6-9 hours when fully drained.
Solid battery icon indicates when battery is very close to fully charged (≥90%), and a power cable icon indicates
the battery is fully charged.

IMPORTANT: When the MantaRay is OFF and the charger is connected, the MantaRay will turn on and display a
charging animation. Pressing the power button or disconnecting the charger will place the meter in the normal
ON Main Screen. You must disconnect the charger and press the power button to return to and OFF state.

MAIN DISPLAY

The main display shows the units selected from the Units/Mode menu, Flow
or Velocity rate being measured, TOTALIZER and RELAY states. The MantaRay
will start-up with this display.

MESSAGE ICON

Press  from the main display to view Data Log state and percent used,
Battery fuel gauge, Charger connection state, Sensor Status (Good, Short,
Open, Dry, Echo Loss), and measured Temperature of the sensor. Press  or
 to return to the Main Display.

STATUS

Press  from the Main Display to view instrument status. Press  or  to
return to the Main Display.

Level The current level measurement displayed in units

selected in the Units/Mode menu.

Velocity The current velocity measurement displayed in

units selected in the Units/Mode menu.

Flow The current flow rate measurement displayed in

units selected in the Units/Mode menu.

Min Flow Read-only value of the currently programmed

Min Flow in the Calibration menu. Any measured
flow less-than Min Flow will result in the Flow
reporting 0.

Signal The current signal strength for the Doppler

velocity measurement, 0-100%. Size of the Signal
Strength depends on velocity and quality of the
Doppler reflectors entrained in the flowing fluid.
Signal of 100% is typical, but Signal all the way
down to just above the default Signal Cutoff
(10%) is also acceptable for very slow moving
fluids.

Signal Cutoff Read-only value of the currently programmed

Signal Cutoff in the Calibration menu. Any Signal
less-than the Signal Cutoff will result in the
velocity stagnating or going to zero depending
on Calibration menu configuration.

Echo Confidence The current echo-confidence for the level

measurement. Echo confidence is the percent
ratio of the number of good echoes received
compared to the number of pulses sent to the
water surface. E.g. if 8 pulses are sent and 8
received, echo confidence is 100%. A level
measurement is considered good as long as Echo
Confidence is above 0%.

CALIBRATION

From the Main Menu, press the  button while the cursor is on Calibration to
access this menu. The configuration parameters available in the Calibration
menu are described below. Use the  or  button to move the cursor up or
down, and the  button to edit the selected parameter.

Some parameter options in Calibration are list types. When changing these
parameters, use the  or  button to choose between the available
selections. Press  to save your selection, or  to cancel.

Some parameter options in Calibration are numerical entry types. When
editing these parameters, use the  or  button to increment/decrement the
selected digit, and  or  to move the cursor position. A decimal point ( . ) or
negative ( - ) may also be available for some positions. Press  to save your
input, or  from the left-most position to cancel.

Default values are shown in the image to the left.

Level Max should be set to the maximum height the level should reach in the
system in units configured in the Units/Mode menu. If a Round pipe is
selected in the Channel Setup menu, then this value should be set to the
same value as the inside diameter of the pipe. The default of 180 inches (15ft)
is equal to the max level the QZ02L sensor can measure.

Level Min should be set to the minimum height the level should reach in the
system, in units configured in the Units/Mode menu. Minimum level for the
QZ02L sensor is 1 inch, however, this value could be set to a larger value if
you want to ignore levels greater than 1 inch.

Level 20mA is only displayed when the Mode in the Units/Mode menu is set
to Level. In this mode, the single 4-20mA output from the MantaRay will
respond to changes in level measurement. This parameter configures the level
equal to a 20mA output.

Level 4mA is only displayed when the Mode in the Units/Mode menu is set
to Level. In this mode, the single 4-20mA output from the MantaRay will
respond to changes in level measurement.

Level Offset is used when the QZ02L sensor is not mounted directly at the
bottom of the channel or pipe, oftentimes when you want to prevent the
sensor from being covered with mud/silt/debris.

PULSAR MEASUREMENT

CALIBRATION (CONT.)

LOE Time is used to suppress a loss in level because of air or debris in the
system. The LOE Time will cause the meter to hold the last valid level reading
when a loss of echo occurs until the LOE Time is expired, at which point the
meter will produce a Loss of Echo alarm message, and the level reading on
the meter will respond according to the LOE Behavior parameter. The default
value for LOE Time is 10 seconds. If you desire that the meter respond quicker
or slower to a Loss of Echo, adjust the LOE Time down or up, respectively. The
MantaRay will automatically being reading level again should the condition
causing the echo loss to go away, and a loss of echo will again require the
LOE Time to count down.

LOE Behavior is used to select behavior for the level measurement when a
loss of echo occurs (after LOE Time expires). Options are either To Zero, which
means the meter will report 0 for the level measurement, or Hold, where the
meter will hold the last valid level reading before the loss of echo occurred.
The meter will therefore use that level for calculating flow should a velocity
also be present.

Level Damping Mode selects the damping algorithm used for level
measurement. Options are FIR, LOW PASS, and OFF.

When new measured levels are outside the Window of the damped output
(value currently reported by the meter), the FIR filter will reduce the number
of measurements used in the damping average so that a faster response can
be made to the sudden change in level.

The LOW PASS filter will ignore new measured levels outside the Window of
the damped output, while holding the damped output until there are enough
consecutive measurements outside the Window to cause a sudden step­response to the new measured value.

While measured levels are within the Window of the damped output (the
current level measurement), both the FIR and LOW PASS filter behave the
same.

Level Damping Percent selects the size of the damping average. Larger
values average more consecutive readings together and cause the meter to
be less responsive to large changes in level measurement. Lower values
reduce the damping average size and cause the meter to be more responsive
to large changes in level measurement.

Level Damping Window sets a boundary around the damped output
(currently reported level), where if the next measured value falls outside the
current value ± window, the meter will make a more rapid response to the
new value (Damping Mode = FIR), or will hold the last reading until enough
consecutive values are outside the window and then make a step response to
the new value (Damping Mode = LOW PASS).

Velocity 20mA is only displayed when the Mode in the Units/Mode menu is
set to Velocity. In this mode, the single 4-20mA output from the MantaRay
will respond to changes in velocity measurement. This parameter configures
the velocity equal to a 20mA output.

13

MANTARAY INSTRUCTION MANUAL

CALIBRATION (CONT.)

Velocity 4mA is only displayed when the Mode in the Units/Mode menu is
set to Velocity. In this mode, the single 4-20mA output from the MantaRay
will respond to changes in velocity measurement. This parameter configures
the velocity equal to a 4mA output.

Velocity Signal Cutoff sets a cutoff where any measured velocity Signal
Strength which is less than the Signal Cutoff will cause the meter to report 0
velocity. This value can be lowered to increase sensitivity in very low flow
situations, at the risk of allowing electrical noise to be measured as actual
flow. This value can be raised to decrease sensitivity, useful for when flow
occurs Signal Strength is very high, yet random noise levels with no flow are
above the default value of 10%. E.g. for an application where when flow is
present, Signal Strength is 100%, yet with no flow the Signal Strength is 50%,
setting the Signal Cutoff to 60% will suppress the unwanted noise with no
flow yet not interfere with the actual velocity measurement when flow is
present.

LOS Time is used to suppress a loss in velocity because of a disturbance
which may interfere with the velocity measurement, like a sudden decrease in
air/solids in the fluid or a sudden increase in turbulence which causes an
inconclusive Doppler measurement. The LOS Time will cause the meter to
hold the last valid velocity reading when a loss of signal occurs until the LOS
Time is expired, at which point the meter will report 0 for the velocity
measurement. The default value for LOS Time is 10 seconds. If you desire that
the meter respond quicker or slower to a signal loss, adjust the LOS Time
down or up, respectively. The MantaRay will automatically begin reading
velocity again should the condition causing the signal loss to go away, and a
loss of signal will again require the LOS Time to count down.

Velocity Damping Mode selects the damping algorithm used for velocity
measurement. Options are FIR, LOW PASS, and OFF.

When new measured velocities are outside the Window of the damped
output (value currently reported by the meter), the FIR filter will reduce the
number of measurements used in the damping average so that a faster
response can be made to the sudden change in velocity.

The LOW PASS filter will ignore new measured levels outside the Window of
the damped output, while holding the damped output until there are enough
consecutive measurements outside the Window to cause a sudden step­response to the new measured value.

While measured levels are within the Window of the damped output (the
current level measurement), both the FIR and LOW PASS filter behave the
same.

Velocity Damping Percent selects the size of the damping average. Larger
values average more consecutive readings together and cause the meter to
be less responsive to large changes in level measurement. Lower values
reduce the damping average size and cause the meter to be more responsive
to large changes in velocity measurement.

CALIBRATION (CONT.)

Velocity Damping Window sets a boundary around the damped output
(currently reported velocity), where if the next measured value falls outside
the current value ± window, the meter will make a more rapid response to the
new value (Damping Mode = FIR), or will hold the last reading until enough
consecutive values are outside the window and then make a step response to
the new value (Damping Mode = LOW PASS).

Flow Min sets a cutoff where if measured flow is less than the Min Flow, the
reading on the LCD display and output signals will report 0.

Flow 20mA is only displayed when the Mode in the Units/Mode menu is set
to Flow. In this mode, the single 4-20mA output from the MantaRay will
respond to changes in flow measurement. This parameter configures the flow
equal to a 20mA output.

Flow 4mA is only displayed when the Mode in the Units/Mode menu is set to
Flow. In this mode, the single 4-20mA output from the MantaRay will respond
to changes in flow measurement. This parameter configures the flow equal to
a 4mA output.

Relay is used to select which of the two relay outputs you wish to
reconfigure. After choosing either 1 or 2, use the Function parameter to select
how you wish to use that relay.

Function is used to set the behavior of the relay selected at the Relay
parameter. Choose between the following functions. Depending on function,
additional options will appear/disappear.

On

Level

Velocity

Will set the associated Relay ON.

Will provide an ON and OFF setpoint for level alarm.
When ON>OFF, the level alarm functions like a high level
alarm. When measured level is greater than ON setpoint,
the relay will turn on, and the relay will turn off when
measured level goes below OFF setpoint. When ON<OFF,
the level alarm will function like a low level alarm instead
with reverse logic as described above. LOE mode is used
to choose how the relay will behave when a loss of echo
occurs. Note: the LOE mode behavior will override any
behavior which would occur due to the LOE Behavior in
the Calibration menu. E.g. if the meter is set to HOLD for
LOE Behavior, and ON for LOE mode, this relay will turn on
regardless if the held level would have the relay off.

Like Level, will provide an ON and OFF setpoint for
velocity alarm. When ON>OFF, the velocity alarm
functions like a high velocity alarm. When measured
velocity is greater than ON setpoint, the relay will turn on,
and the relay will turn off when measured velocity goes
below OFF setpoint. When ON<OFF, the velocity alarm
will function like a low velocity alarm instead with reverse
logic as described above.

Flow

Like Level and Velocity, will provide an ON and OFF
setpoint for flow alarm. When ON>OFF, the flow alarm
functions like a high flow alarm. When measured flow is
greater than ON setpoint, the relay will turn on, and the
relay will turn off when measured flow goes below OFF
setpoint. When ON<OFF, the flow alarm will function like a
low flow alarm instead with reverse logic as described
above.

Direction Used to set the relay to latch ON or OFF depending on

measured flow direction. A requirement for this to work is
to have Rev Flow in the Special Functions menu set to ON
or INVERT. When flow is negative on the main screen, the
relay will turn ON. When flow is positive, the relay will turn
OFF. There is a couple second delay built-in to the relay
changing state, so that there is no chatter near 0 flow
conditions.

Pulse Sets the amount of volume which needs to accumulate for

a relay pulse to occur, in units configured in the
Units/Mode menu. A relay pulse is a 350ms in duration.
Minimum time between pulses is 2.25 seconds. Use this
output to accurately measure volume without having to
integrate the 4-20mA output over time.

Note: The volume accumulation starts from when the new
Pulse value is accepted with the  button. E.g. if the
totalizer was 525 gallons when the Pulse was set to 100
gallons, the next pulse output would occur at 625 gallons.

Off Turns the selected relay OFF.

DATA LOGGING

From the Main Menu, press the  button while the cursor is on Data Logging
to access this menu. The configuration parameters available in the Data
Logging menu are described below. Use the  or  button to move the
cursor up or down, and the  button to edit the selected parameter.

Some parameter options in Data Logging are list types. When changing these
parameters, use the  or  button to choose between the available
selections. Press  to save your selection, or  to cancel.

Some parameter options in Data Logging are numerical entry types. When
editing these parameters, use the  or  button to increment/decrement
the selected digit, and  or  to move the cursor position. A decimal point
( . ) may also be available for some positions. Press  to save your input, or 
from the left-most position to cancel.

Log Site ID is used to enter a number from 00 to 99. The site ID will become
part of the downloaded file name to help distinguish downloads from
different instruments.

Mode is used to select between LVT, Flow, Velocity, and Level mode. Default
is LVT. LVT logs flow rate, level, velocity, and temperature simultaneously.
Flow, Velocity, and Level modes only log the parameter described. It is
suggested to use LVT since it is useful to see the behavior of level and
velocity independently in order to understand flow meter performance. The
Mode cannot be changed when the meter is Logging, you must Stop or
Delete the log first.

Log Mode is used to select the sleep mode behavior of the MantaRay. When
Sleep Btn is selected, the SLEEP button on the front of the meter is used to
put the MantaRay in a low power state, where it will periodically “wake-up”
based on the Interval, and log data before going back to the low power state.
This is used to greatly increase battery life for longer term studies. When Log
Mode is set to Sleep Btn, you will also see the “Zzz” animation on the main
display. When set to Telemetry, pressing the SLEEP button on the meter will
put the meter into a low-power state, but instead of automatically “waking
up” at the proper interval, the MantaRay will wait for a signal from an external
telemetry device, like a SignalFire RANGER, then go back to a low-power
state after being signaled. When in Telemetry mode, there is no “Zzz” on the
main display.

File Format allows you to choose .LG2 to download data in .lg2 format for
viewing on Greyline Logger software. Choose .CSV to download data in .csv
format for import directly to Excel. This menu option can be changed at any
time without adversely affecting existing data.

Date allows you to set the date in MMM DD, YYYY format. It is suggested
that you Delete and Start the log over again after changing the date.

Time allows you set the time in HH:MM:SS format, from 00:00:00 to 23:59:59.
It is suggested that you Delete and Start the log over again after changing
the time.

MANTARAY INSTRUCTION MANUAL

DATA LOGGING (CONT.)

Interval is used to set the length of time between data log entries. Choose
between 10s, 30s, 1min, 2min, 5min, 10min, 15min, 30min, and 60min.

IMPORTANT: Using the SLEEP button when Log Mode is Sleep Btn or
Telemetry will only work when the Interval is 30s or greater. This is because
the amount of time the meter will “wake up” to make a measurement in the
low-power state is longer than the shortest interval – 10s.

Data Log is used to Stop, Start or Delete the log file.

Important Note: You MUST Delete an old log and Start a new log AFTER

having made changes to Log Site ID, Mode, Date, Time and/or Interval for
those changes to be applied.

Important Note: Changing any of the parameters in the Units/Mode menu
will start a new log. It is recommended that you Delete and start a new log
after changing any Units/Mode settings.

RETRIEVING LOG FILE

Plug a USB Flash Drive (one is included with the AVFM 6.1) into the USB
output port on the side of the meter. The main display will show the data
download icon until the log file is transferred to the memory card, at which
point it will show a completed (check mark) icon. The USB flash drive may be
removed when the icon for a successful download appears.

Download filenames will appear in this format: MRAY__0A.LG2, where the “0”
will automatically change to match the Log Site ID from the Data Logging
menu, “A” will increment to “B” and so-on, for each subsequent download of
the data log from one specific meter, and “.LG2” is for File Format LG2 or
“.CSV” for File Format CSV.

Note: Downloading files in .lg2 format will take approximately 35 seconds

per 1% of internal log memory used.

20

PULSAR MEASUREMENT

INSTALLATION – SENSOR LOCATION

For the most accurate flow measurement possible, careful consideration should be made to the placement of the
sensor in relation to flow disturbances. In general, the best accuracy will occur where flow is evenly distributed
across the channel/pipe and free of turbulence.

Specific installation considerations are listed and discussed in more detail below.

1. Open Discharges or Pipe/Channel Outfalls

When the QZ02 sensor is to be mounted in front (upstream) of an open discharge or pipe/channel outfall, the

sensor should be placed at least 5 times the maximum head level in front of the outfall:

2. Hydraulic Dams

When the QZ02 sensor is to be mounted in front (upstream) of a hydraulic dam, or a Greyline VD pipe dam,

the sensor should be placed at least 20 inches in front of the dam.

Important note: Best results when using a dam occur when the pipe/channel grade is less than 1%.

1. Flow Profile Distortion

The pipe/channel in which the QZ02 sensor is mounted should be free of bends, tees, sudden changes in

slope, and there should not be objects in the pipe/channel which disturb the flow profile in front of the
sensor.

In general, the QZ02 sensor should be mounted with at least 10 pipe diameters or channel widths of straight-

run upstream, and 5 pipe diameters or channel widths downstream:

MANTARAY INSTRUCTION MANUAL

SLEEP BUTTON AND TELEMETRY LOGGING INSTRUCTIONS

The Log Mode parameter in the Data Logging menu provides options of Sleep Btn and Telemetry. See the Data
Logging menu description earlier in this manual for instructions on how to set it.

SLEEP BUTTON

In the Data Logging menu, when a Log Mode of Sleep Btn is selected, and the Interval is 30s or greater, pressing
the “SLEEP” button on the front of the MantaRay will put the MantaRay in a low-power state by disabling the front
LCD display and other non-essential electronics. Then, based on the Interval, will automatically “wake-up” essential
electronics to make a measurement before going back to the low-power state. The approximate time for each
sleep measurement is 12 seconds. The LCD display will not turn on while in sleep mode. The analog output will
not activate during sleep button logging.

To bring the MantaRay out of sleep mode, press the “SLEEP” button on the front of the meter. If there is sufficient
battery life, the LCD display will turn back on and you can return to normal operation of the meter. If the battery
has completely drained, you will need to connect the external charger before using the MantaRay again.

IMPORTANT: Pressing the POWER button while the MantaRay is asleep will turn it off, stopping the logging. To
validate that the MantaRay went into sleep mode properly, press the “SLEEP” button to wake it up, then again to
put it back to sleep.

TELEMETRY LOGGING

In the Data Logging menu, when a Log Mode of Telemetry is selected, and the Interval is 30s or greater, pressing
the “SLEEP” button on the front of the MantaRay will put the MantaRay in a low-power state by disabling the front
LCD display and other non-essential electronics. Then, based on an external trigger described in more detail
below, will automatically “wake-up” essential electronics to make a measurement before going back to the low­power state. The approximate time for each sleep measurement is 12 seconds. The LCD display will not turn on
while in sleep mode. The analog output will activate during telemetry logging to send a signal to the external
telemetry device.

Wiring Instructions: In order for the MantaRay to “wake-up”, make a measurement, and transmit the
measurement to an external logger or telemetry system, it requires a DC voltage to be applied to it through the
break-out box. The external DC voltage range is 10-18V. The duration the external voltage is applied should be at
least 12 seconds in order for the MantaRay to stabilize for an accurate measurement and transmit the signal. The
logger/telemetry system should log the 4-20mA output from the MantaRay at the end of the 12 second
measurement cycle.

Wiring instructions for connecting a generic external logger/telemetry system to the break-out box is as follows:

Break-out Box Terminal Marking External Logger/Telemetry Connection

Charger+ DC voltage trigger positive (9-18VDC)
Ext. Bat- DC voltage trigger negative
4-20mA+ 4-20mA input (MantaRay 4-20mA is internally powered)
4-20mA- 4-20mA ground
