Used in conjunction with any Badger Meter impeller flow monitor or transmitter, Badger Meter non-magnetic flow sensors
provide an accurate rate of liquid flow as well as total accumulated flow. A number of sensor models are offered, which cover
applications for a wide range of pipe sizes and pressure/temperature specifications.
The flow sensors generate a frequency which is proportional to flow rate. An internal preamplifier allows the pulse signal to
travel up to 2000 feet without further amplification. Power to operate the sensor is provided by the flow monitor. The impeller
bearing assembly, shaft and O-rings are replaceable in the field.
Badger Meter flow sensors feature a closed, six-bladed impeller design, using a proprietary, non-magnetic sensing
technology. The forward-swept impeller shape provides higher, more constant torque than four-bladed impeller designs,
and is less prone to fouling by water-borne debris. The forward-curved shape, coupled with the absence of magnetic
drag, provides improved operation and repeatability, even at lower flow rates. As the liquid flow turns the impeller, a low
impedance signal is transmitted with a frequency proportional to the flow rate.
Sensors of similar type are interchangeable, so there is no need for recalibration after servicing or replacement.
This manual provides instructions for the following insertion style flow sensors, as indicated:
220BR; 220SS; 220PV; 225BR; 226BR; 226SS
CERTIFICATION
MECHANICAL INSTALLATION
Flow measurement accuracy for all flow measuring devices is highly dependent on proper location in the piping system.
Irregular flow velocity profiles caused by valves, fittings, and pipe bends can lead to inaccurate overall flow rate indications
although local flow velocity measurement may be accurate. A sensor located where it can be affected by air bubbles, floating
debris, or sediment may not achieve full accuracy and could be damaged. Badger Meter flow sensors are designed to operate
reliably under adverse conditions. Follow these recommendations to provide maximum system accuracy:
• Choose a location along the pipe where 10 pipe diameters upstream and 5 pipe diameters downstream of the sensor
provide no flow disturbance. Pipe bends, valves, other fittings, pipe enlargements and reductions should not be present in
this length of pipe.
• The preferred location around the circumference of a horizontal pipe is on top. If trapped air or debris will interfere, then
the sensor should be located further around the pipe from the top but not more than 45 degrees from top center. The
sensor should never be located at the bottom of the pipe, as sediment may collect there. Locations off top center cause
the impeller friction to increase, which may affect performance at low flow rates. Any circumferential location is correct for
installation in vertical pipes.
• Allow an insertion depth of 1-1/2 inches (38 mm) for pipe sizes 2-1/2 inches and larger for accurate flow rate calibration.
Detailed installation instructions for various sensor mounting configurations on the following pages include methods for
providing correct insertion depth.
• Align the sensor so that the impeller rotation is parallel to flow. Alignment instructions are included on the
following pages.

INSTALLATION FOR 220BR, 220SS, 220PV
Installation Procedure
The insertion depth and alignment of the flow sensor assembly are critical to the accuracy of the flow measurement. The flat
end of the sensor sleeve assembly MUST BE INSTALLED 1-1/2 inches (38 mm) from the inside wall of the pipe. To allow for
variations in wall thickness, lining, or coatings, the depth adjustment is controlled by the position of the hex nuts on the three
threaded studs of the hex mounting adapter. The hex mounting adapter is provided with a 2 inch male NPT connection.
There are two methods of mounting these sensors in a 2-1/2 inch or larger pipe. One is with a 2 inch NPT threaded pipe
saddle. The other is with a welded-on fitting such as a Thredolet®, also tapped for a 2 inch NPT connection. In either case, cut a
2 inch (51 mm) hole through a depressurized pipe and then secure the saddle or weld-on fitting to the pipe. (For drilling into
a pressurized pipe, see "Installation into a Pressurized Pipeline" on page 7.) Install the 2 inch NPT adapter provided, using a
thread sealant to prevent leakage. Tighten as necessary. Badger Meter insert style flow sensors are calibrated with the sensor
inserted 1-1/2 inches (38 mm) into the pipe flow.
To determine the proper insertion depth, follow these steps:
1. Apply anti-seize thread lubricant (supplied with the sensor) to the threaded studs of the mounting adapter.
2. Insert the depth gauge into the mounting adapter and set it against the inside wall of the pipe as shown in Figure 1. Set
the top of the upper adjusting nut to 3-3/4 inches (95 mm) as measured. Lock it in place with the bottom nut on the same
stud. Repeat for the other adjusting nuts.
OTE:NFor Model 220PVS, set the nuts 6-1/2 inches (165 mm) above the inside wall of the pipe.

3. Clean the O-rings and the ow sensor sleeve, and lightly lubricate the O-rings with silicone grease from the packet
provided (or another acceptable lubricant). Take care not to get grease on the impeller or bearing.
4. Insert the ow sensor into the 2 inch NPT adapter so that the mounting holes in the positioning collar t over the studs on
the adapter.
5. Lower the sensor onto the previously adjusted nuts. Install the lock nuts on top of the positioning collar and tighten. Now
tighten the lower jam nuts rmly against the upper adjusting nuts to secure them for future removal of the sensor for
inspection or service.

Alignment of Flow Sensor
1. Loosen the positioning collar set screws with a 3/32 inch Allen wrench. Place the alignment rod through the sight holes in
the ow sensor. See Figure 2. Using the alignment rod as a guide, align the ow sensor so the ow label arrow matches the
pipe ow direction and the alignment rod is exactly parallel to the pipe. This procedure aligns the impeller directly into the
uid ow.

2. As a backup to the ow arrow label, there is a small hole next to the larger sight hole of the upstream side. With a
3/32 inch Allen wrench, tighten the positioning collar set screws.
3. Double check that the sight holes in the sleeve are parallel down the pipe and the ow arrow label matches the pipe liquid
ow direction.
4. Cable routing: The positioning collar is threaded for connection of a standard 1/2 inch electrical conduit (ex cable) or a
wire strain relief. Route the cable as required. Be sure to leave enough ex in the cable or conduit to allow future removal
of the sensor for service or cleaning.

Hot Tap Installation for 225BR, 226BR, and 226SS
HOT TAP INSTALLATION FOR 225BR, 226BR, AND 226SS
Badger Meter Series 200 hot tap style liquid flow sensors are designed for use in cases where pipelines will be in continuous
service, and depressurizing or draining the system for installation or service is not practical.
The Series 200 hot tap flow sensors are designed to be installed either in a depressurized pipe by hand, or “hot tapped” into a
pressurized pipeline. Both installation procedures are in this manual. If there is the slightest possibility the pipe could be full or pressurized, follow the installation for a pressurized pipe. See "Installation into a Pressurized Pipeline" on page 7.
See Figure 4 for the location or identification of the various parts described in the following procedures.
Sensor Assembly Depth and Alignment
The insertion depth and alignment of the sensor assembly are critical to the accuracy of the flow measurement. The flat end
of the sensor tube assembly must be installed 1-1/2 inches (38 mm) from the inside wall of the pipe. To allow for variations
in wall thickness, lining or coatings, the depth adjustment is controlled by the position of the hex nuts on the three threaded
studs of the hex mounting adapter. The hex mounting adapter is provided with a 2 inch male NPT connection. Both gate and
ball valve units are provided with 2 inch nipples for mounting onto saddles and weld-o-lets.
Setting the Depth
1. Position the hex nuts 14-7/8 inches (378 mm), minus the thickness of the pipe, from the outside diameter of the pipe. For
example, measure the wall thickness of the pipe from the coupon removed when the 1-7/8 inch (48 mm) hole was cut into
the pipe. If the pipe was 1/8 inch (3 mm) thick, subtract 1/8 inch (3 mm) from 14-7/8 inches (378 mm), or position the nuts
14-3/4 inches (375 mm) from the outside diameter of the pipe. This will allow the 16-3/8 inch (416 mm) sensor to protrude
1-1/2 inches (38 mm) into the pipe.
2. Apply anti-seize thread lubricant, supplied with the sensor, to the threaded studs of the mounting adaptor.
Aligning the Impeller with the Flow
1. To align the impeller with the ow in the pipe, align the two sight holes at the top of the sensor tube assembly with the
center line of the pipe. Make sure the alignment is made to the pipe, and not to a wall or surface near the sensor.
2. To adjust, loosen the two set screws in the positioning collar with the 3/32 inch Allen wrench (supplied in the
installation kit).
3. Slip one end of the 1/4 inch x 18 inch steel rod (supplied in the installation kit) through the holes in the sensor tube.
4. Rotate the sensor tube until the rod is centered on the pipe. Make sure the ow label arrow on the sensor matches the
liquid ow direction.
5. Tighten the positioning collar Allen screws to lock the sensor sleeve assembly in position.
OTE:NAs a backup to the flow label arrow, there is a small hole located beside one of the sight holes to also indicate the
upstream side of the sensor.

Hot Tap Installation for 225BR, 226BR, and 226SS
Installation if the Pipe is Depressurized and Drained
1. Drill or cut a hole in the pipe with a 1-7/8 inch (48 mm) drill or hole saw. Note the pipe wall thickness for use in calculating
sensor assembly depth. A location on the top of the pipe is best for overall performance and service life; however,
any radial location on the top half of the pipe is acceptable. Allow a minimum of 10 pipe diameters upstream and 5
downstream from the sensor of straight unobstructed pipe to allow full development of the ow prole.
2. Install either a service saddle or welded pipe tting (2 inch female NPT) on the outside diameter of the pipe over the 1-7/8
inch (48 mm) hole.
3. Install the Badger Meter isolation valve and nipple onto the tting using pipe thread sealant or Teon® tape on all threads.
4. Install the Badger Meter hex mounting adapter onto the valve assembly. Use pipe thread sealant on the adapter.
5. Tighten the hex mounting adapter so that no stud is aligned with the center-line of the pipe. This could interfere with nal
sensor alignment.
6. Measure the depth and set the height of the nuts of the hex mounting adapter.
OTE:NBadger Meter recommends that you purchase a Hot Tap insertion/removal Tool (Model HTT) for future service,
even if the sensor is installed in a drained system. The Model HTT allows you to remove the sensor sleeve
assembly from the pipe line without draining the entire loop where the sensor is mounted.
7. In a fully depressurized and drained pipe, the sensor tube assembly may be installed by hand. If reinstalling into a drained
system thought to have been depressurized and drained, verify by very slowly opening the isolation valve.
a. Carefully and very slowly open the isolation valve to relieve any pressure that may have built up.
b. Fully open the isolation valve.
c. Push the sensor sleeve into the pipe with a slight twisting motion.
d. Guide the sensor collar holes over the three hex adapter studs until the collar rests on the nuts. Hex nuts should have
been previously set to the correct height.
e. Install the three lock nuts onto these studs at the top of the positioning collar and securely tighten.
8. Loosen the two set screws in the positioning collar with a 3/32 inch Allen wrench.
9. Align the sensor sight holes along the pipe axis using the alignment rod from the sensor installation kit. M
10. Verify that the ow label arrow on the sensor matches the liquid ow direction inside the pipe.
11. Tighten the positioning collar set screws.
OTE:NAs a backup to the flow label arrow, there is a small hole located beside one of the sight holes to also indicate the
upstream side of the sensor.
Installation into a Pressurized Pipeline
The Model HTT (Hot Tap Tool) provides the mechanical
advantage required to safety insert and remove a
Badger Meter hot tap flow sensor from line pressure, and
provides a restraint when removing the sensor from a
pressurized pipe.
Refer to Figure 3 for identification and location of the HTT
parts described in this section.
For pipe sizes 2-1/2 inch and above, all Badger Meter sensors
are inserted 1-1/2 inches (38 mm) from the inside wall of the
pipe. The insertion depth is controlled by the position of the
hex nuts on the three threaded rods.
To calculate the distance (D) between the top of the sensor
hex mounting adapter and the bottom of the positioning
collar (the top of the hex nut), ADD the H dimension, pipe
wall thickness, and insertion depth, and SUBTRACT the total
from the overall sensor length. See the example and formula
on the next page, and refer to Figure 4.

JAM NUT
Hot Tap Installation for 225BR, 226BR, and 226SS
Example: The sensor is installed in an 8 inch schedule 80 pipe, with a pipe wall thickness of 1/2 inch. If the overall sensor
length is 16-3/8 inches and the H dimension is 10 inches, the D value is calculated as follows:
D = Overall length − (H + pipe wall thickness + Insertion Depth)
D = 16-3/8 in. − (10 in. + 1/2 in. + 1-1/2 in.)
D = 16-3/8 in. − 12 in.
D = 4-3/8 in.
Figure 4: Sensor parts
1. Set one set of the hex/jam nuts so that the distance between the top surface of the hex nut and the top surface of the hex
mounting adaptor is equal to the D dimension calculated above.
2. Then adjust the other two sets of hex/jam nuts 1-1/2 inches (38 mm) below the rst jam nut to allow clearance for the
Model HTT (Hot Tap Tool) top yoke.
3. Fully extend the HTT by turning the drive nut counterclockwise with a 15/16 inch socket or box wrench (customer
supplied) until the drive nut contacts the tool. Slide the positioning collar into the tool top yoke.
4. Remove the HTT split ring and clevis pin and slide the tool bottom yoke into the groove on the sensor hex mounting
adaptor. Secure by replacing the clevis pin and split ring.
5. Mark the sleeve 2-3/4 inches (51 mm) from the impeller end of the metal sleeve. This mark is a stopping point to prevent
the impeller/bearing from being damaged.
6. Open the bleed petcock valve on the hex mounting adapter to relieve the pressure resulting from the ow sensor
sleeve insertion.
7. Carefully hand insert the hot tap ow sensor sleeve assembly into the hex mounting adapter until the mark lines up with
the top of the hex mounting adapter. At this point, the sleeve will have been inserted past the top two O-rings in the
adapter, approximately 1…1-1/4 inches (25…32 mm). Take care not to push the sensor past the mark on the sleeve as the
impeller could be damaged if it strikes the closed valve.
8. Rotate the HTT so the threaded rod with the adjusted hex/jam nuts is centered in the top yoke of the hot tap tool.
9. Rotate the sensor sleeve so the positioning collar holes align with the threaded rods and ow direction label is in general
direction making sure the positioning collar is located in the recessed area of the top yoke.
10. Slide the top yoke of the HTT over the positioning collar and secure by tightening the two thumbscrews on top of
the yoke.
11. Close the bleed petcock and slowly open the isolation valve.
12. Slowly turn the 15/16 inch drive nut clockwise to insert the sensor sleeve assembly through the valve and into
the pipeline.
13. Carefully guide the three threaded studs of the hex mounting adapter through the holes of the sensor positioning collar.
14. Carefully lower the sensor until the positioning collar contacts the hex nut preset for the correct depth adjustment.
Page 8 February 2018SEN-UM-01635-EN-11
Hot Tap Installation for 225BR, 226BR, and 226SS
15. Install the three lock nuts onto the threaded rods, tightening only the lock nut on the threaded rod with the preset hex/
jam nut.
16. Then bring the two remaining lock nuts down until they just contact the positioning collar. Do not tighten at this time.
17. Remove the HTT by loosening the two thumbscrews, removing the clevis pin and sliding the insertion tool o the sensor.
Then bring the two remaining sets of hex/jam nuts up to the underside of the positioning collar and tighten.
18. Align the sensor by loosening the two set screws in the side of the positioning collar with a 3/32 inch Allen wrench.
19. Align the sensor sight holes along the pipe axis using the alignment rod from the sensor installation kit. Make sure the
ow label arrow on the sensor matches the liquid ow direction inside the pipe.
20. Tighten the positioning collar set screws.
OTE:NAs a backup to the flow label arrow, there is a small hole located beside one of the sight holes to also indicate the
upstream side of the sensor.
For removal of a Series 225, 226 flow sensor from a pressurized pipeline, refer to the document titled Hot Tap Flow Sensors Application Data Sheet, available in the Resource Library at www.badgermeter.com.

ELECTRICAL INSTALLATION SAFETY
The Series 200 sensor is approved, as an entity, as intrinsically safe when installed in conformance with Badger Meter
installation drawing 06-480-002 (Figure 5) as specified on the blue label identifying an intrinsically safe sensor.
Entity approval implies that only the sensor is approved as intrinsically safe. Unless power supplies, equipment, and
instruments connected to the sensor are each rated either explosion-proof or intrinsically safe, these devices cannot be
installed in a hazardous area. The referenced installation drawing shows such apparatus located in a non-hazardous location.
Proper interfacing between the hazardous and non-hazardous areas must be provided. It is of absolute importance that
this interface be constructed and that all wiring be performed by qualified contractors. To protect the intrinsic safety of the
installation, the connection of the intrinsically safe sensor to instruments and or power supplies must take place using an
approved intrinsically safe barrier located in a non-hazardous area. These barriers, listed below, are readily available from
various suppliers.

Calibration
CALIBRATION
Badger Meter sensors use unique K and Offset numbers for calibration. These numbers are derived from calibration runs using
NIST traceable instruments. Using both a K and an Offset number provides higher accuracy than using a K (pulse/gal) factor
alone. K and Offset numbers for each tee configuration are listed in the following tables.
The "Calibration Table for Pipe Sizes 3…36 Inches" on page 14 provides calibration and operation data for most scheduled
pipe sizes 3…18 inches. For tee-mounted sensors, see the Metal Tee or the Plastic Tee user manual, available in the Resource
Library at www.badgermeter.com.

Freq=
This equation describes the frequency of the output signal of all Badger Meter flow sensors. By substituting the
appropriate K and Offset values from the table, the sensor’s output frequency can be calculated for each pipe size.
This information is required when calibrating an output board or when using the raw sensor data as direct output to
interface with a device that is not a Badger Meter product.
Column 6This column indicates the suggested flow range of sensors in each pipe size. Badger Meter sensors will operate
both above and below the indicated flow rates. However, good design practice dictates the use of this range for
best performance.
Sensors should be sized for flow rather than pipe size. To prevent disturbances to the flow profile, always connect
the sensor tee to the pipe nipples measuring at least ten pipe diameters in length on the downstream (delivery) side
before making the transition in pipe size.

IMPELLER ASSEMBLY AND SHAFT REPLACEMENT
If you are replacing an existing Badger Meter sensor and have already calibrated your flow monitor/transmitter, no calibration
changes are necessary. For installation of a new flow monitor or for relocation of a sensor in a new pipe size, see the
calibration instructions in this manual.
1. Depressurize the pipe from which the sensor is to be removed. If the sensor is one of the Series 225/IR225 or 226/IR226,
consult the installation section on hot tap sensors. NEVER disturb the securing lock nuts on a pipe under pressure
without the hot tap insertion tool Model HTT installed.
2. Remove the three lock nuts that secure the positioning collar to the threaded rods of the metal sensor.
OTE:NBefore removing the lock nuts, record the dimension from the top of the 2 inch NPT adapter to the bottom of the
positioning collar. This dimension will be required later to reinstall.

3. Remove the sensor from the hex adapter or the tee.
OTE:NNote the impeller blade orientation relative to the flow arrows and the alignment hole in metal sensors beside
one of the sight holes. To maintain proper calibration, the impeller must be reinstalled in the same manner, with
the impeller blades pointing toward the small alignment hole, and into the flow direction as indicated by the
flow arrows.
4. To remove the old impeller blade assembly, push the old shaft out of the sleeve with the new shaft (or small diameter rod)
just far enough to grab the end with a pair of pliers and pull the shaft completely out. The impeller assembly will now be
free and will drop out.
5. Inspect the shaft and bearings for wear, and replace as necessary.
6. See Figure 5. To reinstall, position the impeller in the cavity, oriented as in the NOTE above, so that the impeller blades
point into the ow direction and toward the alignment hole located beside one of the sight holes on the metal sensors.
7. Carefully push the shaft through the sleeve and impeller, taking care not to damage the bearings. Make sure that the shaft
is inserted far enough so that it clears the sleeve on each side of the impeller housing.
OTE:NIf the shaft is not carefully installed, the bearing can be deformed preventing free rotation.
8. Inspect the O-rings for damage and replace as necessary. Clean the O-rings and the sleeve and relubricate with silicone
grease from the packet provided or some other acceptable lubricant.
9. Install the sensor into the 2 inch NPT adapter or tee so that the alignment hole is facing upstream and ow arrows point
in the direction of the actual ow. Since the positioning collar was not loosened during this operation, the studs should all
line up perfectly when the sight holes are parallel to pipe. If this has been accidentally loosened, see "Electrical Installation
Safety" on page 11.
10. Install and tighten the nuts.
11. For metal sensors, double check that the distance from the top of the 2 inch NPT adapter to the bottom of the positioning
collar equals the dimension as measured in Step 2, and holes in sleeve sight exactly down the pipe, the arrows point
in the direction of ow, and alignment holes located beside one sight hole are pointing towards the source. If not, see
"Mechanical Installation" on page 3.
This completes the replacement procedure. The system can now be repressurized and tested.

Troubleshooting
TROUBLESHOOTING
1. If the voltage at the sensor input is less than 7V DC in a no ow situation, disconnect the sensor from the barrier strip and
measure the voltage again at the sensor input terminals of the barrier strip. It should be between 8…20V DC. If the voltage
at the sensor input is still below 7V DC or 3V DC, the problem may be with the monitor (hardware or programming).
2. If you suspect that the sensor is bad, you can test the monitor circuitry by connecting a piece of wire to one of the sensor
input terminals, and tap the other side of the wire to the other sensor input terminal. Shorting across the sensor input
terminals ON and OFF repeatedly allows the display to respond by trying to calculate a ow rate for the frequency of your
shorting action. If the display does not show a change from 0.00, it indicates a problem with the monitor.
3. If the monitor tests OK and there are any splices in the cable, break the sensor cable at the splice closest to the sensor and
retry the shorting test in Step 2.
4. If the cable tests OK, drain the pipe line, verify the pressure is o, and remove the top lock nuts holding the sensor
electronics. Spin the impeller by hand. If ows are noted on the display, and the impeller spins freely, then the ow rates
may have been below the design minimums, or the line was full of air. Try again. If the sensor fails to respond then replace
the sensor.
