INTRODUCTION
The RNL vortex shedding ow meters are designed to provide accurate and repeatable liquid ow measurements in a variety
of common ow measurement applications. The ow meters employ a patented ultrasonic technique to measure a form of
turbulence created in the ow stream. This turbulence, know as a Von Karman Vortex Street, is related to the volumetric ow
through a full pipe.
An everyday example of a vortex shedding phenomenon is a ag waving in the breeze: the ag waves due to the vortices
shed by air moving across the
agpole.
Within the ow meter, as a uid
moves across a strut or “blu body”,
vortices are also shed but on a
smaller scale. The vortices form
alternately, from one side to the
other, causing pressure uctuations.
The alternating pressure changes are
detected by the piezoelectric crystals
in the sensor tube, and are converted
to an analog signal or pulse output.
The frequency of the vortices is
directly proportional to the ow. This
results in extremely accurate and
repeatable measurements with no troublesome moving parts (see Figure 1).

Counter
The ow meters primary output is a 4-20 milliampere (mA) current. The value of the current output is proportional to the ow
rate. The secondary output is a pulse train whose frequency is directly proportional to the ow.
Each RNL ow meter is calibrated against ow standards traceable to NIST (National Institute of Standards and
Technology).
The RNL ow meter is an insertion style retractable ow meter, for pipe sizes 4 inches (102 mm) and larger. The meter is
usually installed through a 2 inch full port isolation valve (See Figure A4), which permits the meter to be retracted or inserted
without shutting down the system.
The RNL series ow meters are calibrated in actual volumetric ow rates, such as gallons per minute (GPM) and comes with a
standard rate and total display.

INSTALLATION
MECHANICAL INSTALLATION
The ow meter is shipped completely assembled, tested and ready to install and operate in its permanent location. See Figure
3 for the applicable outline dimensions for the ow meter. See the Appendix for additional installation information.
Installation Location
The RNL series ow meters use a combination of ultrasonic and vortex shedding technologies to measure volumetric ow. An
ultrasonic noise source can interfere with this technique, therefore the meter should not be installed near high intensity ultrasonic
noise sources. Common ultrasonic noise sources include the following:
» Slightly open valves operating with large pressure drops.
» Small pipe leaks in high pressure systems.
» Venturis operating at near-sonic ow rates.
» Sonic nozzles.
If these ultrasonic noise sources cannot be eliminated, the meter should be mounted with at least one elbow between the ow
meter and the noise source remembering to keep in mind the straight pipe run requirements as described next.
The sensor should be installed with at least 20 pipe diameters of straight pipe upstream and 10 pipe diameters downstream.
This condition provides a fully developed, symmetrical ow pro le that is necessary to obtain accurate and repeatable results.
Shorter upstream/downstream piping may be used, although a shift in calibration may occur. If severe turbulence or distorted
ow pro les are present, ow straighteners should be used. Consult factory for shorter upstream/downstream con gurations.
When installing the ow meter in a newly constructed process line, a strainer should be installed upstream of the meter to
prevent foreign material from damaging the meter strut or obstructing the ow. Damage to the strut could a ect the accuracy
of the meter.
In order to prevent cavitation, it is important that the required back pressure be maintained. The minimum required back pressure
varies with temperature. See the back pressure calculations in Figure 2. The sensor should be installed using the minimum piping
requirements indicated in Table 1.
Maximum volumetric ows are determined by the inside diameter of the pipe and the velocity of the uid being measured.
Calculations of minimum and maximum ow ranges are based on the pipe being full at all times. See Table 2 for ow ranges in
common pipe sizes.
BACK PRESSURE CALCULATIONS
At high ow rates, cavitation may occur, causing a ow meter to be inaccurate. Cavitation can be prevented by increasing the
back pressure. The following equation determines the minimum back pressure required to prevent cavitation:
P1 = PVP + 0.03 V
where: P1 = line pressure at the meter PSIA
P
V = line velocity FPS
EXAMPLE: In water at 65° F owing with a speed of 25 fps, the vapor pressure is 0.3 PSIA.
P1 = 0.3 + 0.03 (25)2 = 19.05 PSIA If atmospheric pressure is 14.69 PSIA,:
Then P1 = 19.05 PSIA - 14.69 PSIA = 4.36 PSIG
= vapor pressure of the liquid PSIA
VP
²
Maintaining a back pressure of 5 PSIG or greater will prevent cavitation.

The RNL Series ow meters are designed to mount on a standard ANSI 150 lb., 2” pipe ange. It is recommended that the customer
conduct a ow pro le survey and place the probe at the optimum point. The labeling of the ow direction on the sensor should
be aligned with the ow in the pipe. Maximum insertion depth is a product of pipe size and uid velocity, see Appendix Table
A1 for Insertion Depth Chart.
CAUTION: Avoid bending the vortex strut or damaging the transducers during installation. The torque value for
the Conax tting is 90-100 ft. lbs.

Wiring
A two conductor cable of 16 to 24 AWG solid or stranded wire is required to make connections to the ow meter. It is recommended
that a shielded interconnecting cable be used. The maximum cable length for the power depends on the supply voltage lines
required to drive the ow meter and the current meter being used to monitor the current output of the ow meter. The maximum
length of the cable is determined by using Figure 5 to calculate the maximum load (resistance in Ohms) that can be driven using
the known power supply voltage. In determining this value the voltage drop across the meter being used to monitor the current
output of the ow meter must be considered. After this value has been found, Table 3 can be used to calculate the resistance in
the cable being used and adjust the input voltage as required.
Ohms/Ft Related to Wire Size (AWG)
16 AWG = 0.00420 Ohm/Ft
18 AWG = 0.00651 Ohm/Ft
20 AWG = 0.01035 Ohm/Ft

Pulse Output
The pulse output is a secondary output and is not intended for long transmission. The load on the line must be 50 kilohm
minimum and 1,000 picofarads (pf) maximum.
The maximum length of shielded cable that can be attached to this output is 100 feet.
Cable Installation
To install the cable in the ow meter, route the cable through the cable gland located on the electronics enclosure.
The wiring of the other end of the cable will vary depending on the speci c installation requirements. Figures 6, 7, and 8 show
the wiring diagram for variations of ow meter installation.
The ow meter’s 4 position terminal strip provides all the connections needed to operate the ow meter.
+ 4-20 mA Terminals
The + 4-20 mA terminals are used for the ow meter’s power supply. This power supply should be 10 to 30 Volt DC and be capable
of supplying 25 Milliamp to the ow meter. Because this meter has a built-in display no additional wiring is necessary for basic
operation (See Figure 6).

Speci c Gravity (SP GRAV)- The speci c gravity for the uid being measured must be entered if mass readings are desired. The
SP GRAV (speci c gravity) prompt will only be displayed when one of the mass Rate Units is chosen.
Low Flow Cuto (FL C OFF) - The low ow cuto is entered as an actual ow value between maximum ow and minimum ow
and in uences how the ow meter will act at ows very near zero. Generally, an entry of 2% of the maximum ow provides for
a stable zero indication. When the ow rate drops below the entered value, the meters’ display will read zero.
Damping (DAMPING) - The damping value is increased to increase stability of the ow rate readings. Damping values are
decreased to allow the ow meter to react faster to changing ow rates.
Flow 4 mA Setting (FLOW 4MA) - If the 4-20 mA analog output is to be used the ow rate that corresponds to 4 mA must be
set. If the current selection is correct, press the ENTER key once to advance to the next parameter. If adjustment is required, use
the arrow keys to input the correct 4 mA setting. The arrow key moves the active digit one place to the right for each press of
the key. The arrow key increments the active digit one integer for each press of the key. When the correct 4 mA ow rate has
been entered press ENTER once to store this value and move to the next parameter.
Flow 20 mA Setting (FLOW20MA) - If the 4-20 mA analog output is to be used the ow rate that corresponds to 20 mA must
be set. If the current selection is correct, press the ENTER key once to advance to the next parameter. If adjustment is required,
use the arrow keys to input the correct 20 mA setting. The arrow key moves the active digit one place to the right for each
press of the key. The arrow key increments the active digit one integer for each press of the key. When the correct 20 mA ow
rate has been entered press ENTER once to store this value and move to the next parameter.
4-20 mA Calibration (4-20CAL?) - The 4-20 mA calibration menu allows the ne adjustment
of the 4-20 mA output. The 4 mA setting is typically between 35 and 50. To set the 4 mA value,
connect an ammeter in series with the loop power supply. At the 4-20CAL? prompt press ENTER
once. The display will now show a steady NO indication. Press the arrow key to change to a
YES display. Press ENTER once to access the 4 mA ne adjustment.
4 mA Adjustment (4MA OUT) - While monitoring the ammeter, adjust the
4 mA value to obtain a 4 mA reading. The arrow key increments the value
and the arrow key decrements the value. When a steady 4 mA reading is
obtained on the ammeter press the Enter key to lock in this value and move
to the 20 mA adjustment.
20 mA Adjustment (20MA OUT) - The 20 mA adjustment is preformed using
the same procedure as the 4 mA adjustment.
While monitoring the ammeter, adjust the 20 mA value to obtain a 20 mA
reading. The arrow key increments the value and the arrow key decrements
the value. When a steady 20 mA reading is obtained on the ammeter press the
Enter key to lock in this value and move to the next parameter.
4-20 mA Test (4-20TEST)- The monitor contains a diagnostic routine that allows
the simulation of mA values between 4 and 20 to check output tracking. At the
4-20TEST prompt the arrow keys change the simulated mA output in increments
of 1 mA. The ammeter should track the simulated mA output. If a 4-20 mA test is
not necessary press MENU once to move to the next parameter.
FIGURE 9 420 mA TEST SETUP
Password (PASSWORD) - Password protection prevents unauthorized users from changing programming information. Initially
the password is set to all zeros. To change the password press ENTER once at the password prompt. The rst digit of the password
value will begin to ash. Using the arrow keys as previously described enter the password value. Pressing ENTER will store the
password and exit to run mode.
09-VRX-UM-00408 07/12
15
Advanced Setup (ADV STUP) - The advances setup menu allows access to entries for applying scaling factors, enabling or
disabling the pulse output, and adding linearization points.
At the ADV STUP prompt press ENTER once. The display will now show a steady NO indication. Press the arrow key to change
to a YES display. Press ENTER once to access the rst parameter.
Scale Factor (SCALE F) - At the SCALE F prompt press the ENTER key once. The current scale factor will begin to ash. If the
current selection is correct, press the ENTER key to advance to the next parameter.
The scale factor is used to force a global change to all variables. For example, under operating conditions the display is reading a
consistent 3% below the expected values at all ow rates. Rather than changing all parameters individually the scale factor can
be used to compensate for the 3% o set. The scale factor would be set to 1.03 to correct the readings.
The range of scale factors is from 0.5 to 1.5. The default scale factor is 1.00. A scale factor is used to correct (correlation adjustment)
or change the ow value displayed on the LCD.
A correlation adjustment allows the user to “force” the display to read a ow value di erent from the factory calibrated value.
This procedure is only valid for an “o set” di erence. In other words the readings must be o by a constant value or percentage
for the entire measurement range.
Totalizer Pulse Output (PULS OUT) - The pulse output parameter can be either enabled or disabled. When enabled this output
generates a 20 mS duration pulse for every time the least signi cant digit of the totalizer increments. The amplitude of the pulse
is dependent on the voltage level of the supply connected to the pulse output and is limited to a maximum 30 VDC.
Linearization (LINEAR) - Enhanced accuracy can be obtained by linearization of the display. The linearization routine will accept
a maximum of ten points. Linearization requires additional calibration data from the sensor to be used with the monitor. Typically
calibration information is obtained for three, ve, or ten points.
Number of Points - At the LINEAR prompt press ENTER once. The rst display number will begin to ash. Again the arrow
key increments the value and the arrow moves the cursor between digits. Enter the number of linear points to be used.
When the number of points has been input press the ENTER key once to move to the rst linear segment.
Press the ENTER key once and the rst linear point's frequency input will begin to ash FREQ 1. Enter the frequency for the
rst linear point using the arrow keys. When the frequency value input is completed, press ENTER once again to change to
the coe cient value for the rst linear point.
At the COEFF 1 prompt enter the coe cient that corresponds to the frequency value previously entered. Press ENTER once
to move to the next scaling point.
Continue entering pairs of frequency and coe cient points until all data has been entered.
TOTALIZER FUNCTIONS
Reset Total - To reset the monitor total display, in run mode press MENU and ENTER simultaneously until TOTAL RST starts to
ash. The TOTAL RST will stop ashing and the display will return to run mode at the conclusion of the reset procedure.
Store Total - The current total can be manually stored in the monitors ash memory. Press and hold the ENTER key for 2 seconds.
The display will respond with a ashing TOTALSVD and then start a display test. At the end of the test the instrument will return
to run mode.
Automatic Store Total - The monitor is equipped with a store total feature that works automatically saving the current total to

TROUBLESHOOTING
The RNL series ow meters are designed to ensure long term accuracy and reliability. The material used for construction and
self-cleaning strut are speci cally designed to withstand the rigors of industrial environments.
As a result, periodic adjustments or re-calibration is not required. The following section is intended as a guide to eliminating
common problems found with the installation of the ow meters. Technical assistance is also available directly from Badger
Meter, who also provides complete re-calibration and repair service for the RNL series ow meter at nominal cost.
1) Is the ow meter cable installed correctly?
2) Is the proper power supplied to the correct terminals?
3) Is the ow meter installed with the ow direction arrow aligned with ow in the pipe?
4) For insertion style ow meters has the sensor head been inserted to the optimum depth?

ADDITIONAL INSTALLATION REQUIREMENTS
Introduction
Installing a ow meter is something which requires careful consideration. It cannot just be placed in a line somewhere and be
expected to ful ll its purpose adequately. The geometry and condition of the pipe runs in the area of the installation must be
considered to ensure the best and most accurate operation of the ow-meter. This appendix provides suggestions for optimum
installations.
Most flow meter manufacturers define installation conditions in terms of upstream and
downstream straight pipe lengths from the point of installation. Unfortunately this is not the
only requirement, and one needs to consider other peripheral conditions, such as proximity and
style of bends, and other equipment installed in the line. By doing this, problems of turbulence,
swirl, and sonic noise may be avoided.
Turbulence
Turbulence is a disturbance of the ow caused by bends and
obstructions in the ow stream (it is this phenomenon which
makes the vortex ow meter work). Fortunately turbulence dies
out fairly quickly, so by positioning the ow meter well away from
bends and obstructions this potential problem of measuring ow
in turbulent conditions is overcome (See Figure A1).
FIGURE A1 TURBULENCE
Swirl
Unlike turbulence, swirl will not die away. Once created it will
continue until dissipated on the next pipe bend in
the system. Swirl occurs after two bends, in close
proximity, which are at an angle to each other.
When designing an installation, keep the ow
meter out of any line which has two adjacent
bends upstream. (See Figure A2).
Sonic Noise
Sonic noise is created by valves (either ow control or pressure control valves)
which are slightly open. Like swirl, sonic noise will only dissipate on a
bend so it is important to install ow meters out of line of sight of
valves. Sonic noise is caused by liquid obtaining sonic velocities
through a slightly open valve which has a pressure di erence
across it. This noise travels both up and down stream from
the valve therefore the ow meter must be installed well
away from the valve, preferably around a bend (See Figure
A3).

Velocity Pro le for RNL Insertion Meters
When using an RNL series insertion ow meter, it is necessary to consider the e ects of the velocity pro le across the pipe or
duct to optimize accuracy.
In large pipes, the ow moves slowly at the pipe walls but is at maximum velocity in the center of the pipe creating a continuously
variable velocity across the pipe. This velocity variation is called the velocity pro le of the pipe, and can be measured and plotted
by using the insertion ow meter to measure velocities at various noted positions across the pipe. As the maximum velocity is
in the center of the pipe, it follows that if the ow meter is positioned in the center, it will not measure average ow. The “rule
of thumb” position is 25% of the pipe ID into the pipe, but the optimum position can only be obtained by measuring the pro le
and working out the correct position from that.
Straight-Run Piping Considerations
The sensor should be installed with 20 diameters, or more, of straight, unobstructed, full area pipe upstream of the ow meter
installation and 10 diameters, or more, downstream. This condition provides a fully developed, symmetrical ow pro le that is
necessary to obtain accurate and repeatable results. The rst obstruction up and downstream should be a full area elbow. If the
minimum straight run is not possible, the general rule is to have 80% of the straight run upstream and 20% downstream from
the ow meter installation.
High intensity ultrasonic noises should not be located upstream or downstream from the sensor. Common ultrasonic noise
sources include the following:
● Slightly cracked valves operating with large pressure drops.
● Small pipe leaks in high pressure systems.
● Venturies operating at near-sonic fl ow rates.
● Sonic nozzles.
If these ultrasonic noise sources cannot be eliminated, the meter should be mounted with at least one elbow between the ow
meter and the noise source.
Temperature and Pressure Tap Locations
User supplied pressure and temperature sensors should be mounted downstream from the ow meter. The pressure sensor
should be approximately 3-5 pipe diameters and the temperature sensor approximately 4-8 pipe diameters downstream.
RNL Insertion Style Meter Installation
The RNL series ow meter is shipped completely assembled, tested and ready to install and operate in its permanent location.
If the main line can be depressurized easily without undue user inconvenience, then a simple installation, consisting of a 2 inch
(51 mm) nozzle and a standard ANSI 150 pound, 2 inch pipe ange may be used. This permits the shortest shaft length to be used,
which keeps clearance space requirements for insertion and removal to a minimum. Gaskets (not provided) are necessary between
the sensor and ANSI ange. It is recommended that the customer conduct a ow pro le survey prior to installing ow meter.
DANGER - Caution should be used when inserting or retracting at pressures exceeding 60 PSIG (4.14 BARg).

HOT TAP INSERTION FLOW METER INSTALLATION
Where de-pressurizing the line for ow meter maintenance is impossible or undesirable, the “hot tap” method of installation is
used. This method involves inserting the ow meter through a 2 inch (50.76 mm) spool piece and a 2 inch (50.76 mm) full port
valve and will require a longer shaft length as well as greater clearance space for removal and installation.
DANGER - Caution should be used when inserting or retracting at pressures exceeding 60 PSIG (4.14 BARg).

For pipe diameters greater than 24 inches (609 mm):
Calculate the distance from the top of the ow

Where a flow profile is desirable, calculate the
distance from the bottom of the pipe to the top
of the ow meter mounting ange and subtract 2
inches (50.76 mm). Round this distance up to the
next largest 12 inches (305 mm) increment. This is
the stem length that should be ordered.

Insertion meters are subject to damage from bending if the uid velocity
exceeds a speci c value. The threshold velocity where damage may occur is
found in a lookup table (See Table A1) and the depth the meter stem
extends into the pipe (See Figure A6).
L1 = Distance from bottom of ow meter ange to center of vortex strut.
L2 = Distance from bottom of ow meter ange to top inside wall of pipe
1) Find the appropriate L1 distance for your application in the rst
column.
2) Once the L1 distance is identi ed, move across the row until the
appropriate L2 distance is located for the application. The resulting
number is the maximum uid velocity.
EXAMPLE: L1 length = 24, and L2 length = 12.
Using Table A1 follow the 24” (L1) row until it intersects the 12” (L2)
column. L1 and L2 intersect at 13 ft/sec. Exceeding the maximum
uid velocity of 13 ft/sec risks bending the meter stem.

FLOW PROFILING
If the purchased ow meter is long enough to be inserted to the far side of the pipe, the ow through the pipe may be pro led
at various ow rates. The goal is to nd a point in the pipe that remains a consistent percentage of the average ow rate over a
wide range of ow. A sample ow pro le is shown in Table A2. In this example, the ow rate of a 48 inch pipe is measured every
six inches across the diameter of the pipe beginning and ending 3 inches from the near and far sides of the pipe. The distance
in inches from the nearside of the pipe is shown. Measurements are taken at a low, medium and high average ow. In Table
A3 the ow rate at each measurement point has been converted to a percentage of the average ow. It can be seen that point
number three (15 inches from the near side of the pipe) reads a consistent 102 percent of the average ow. The meter should
be placed in this position and the output should be divided by 1.02 to obtain the correct reading. Flow pro ling should be done
for all insertion meter installations.

REDUCING THE PIPE DIAMETER
To decrease the variation of ow pro le, the piping can be narrowed at the ow meter as shown in Figure A7. This will smooth
the ow and increase the e ectiveness of ow pro ling. Nearly any angle can be used on the down-stream side of the meter to
restore the original pipe diameter. However, if the angle of piping is seven degrees or less, nearly all the pressure drop caused
by the narrow pipe section will be recovered.
