Introduction
INTRODUCTION
The Badger Meter SDI Series impeller flow sensor offers unparalleled performance for liquid flow measurement in closed pipe
systems in an easy to install economical package. Impeller sensors offer a quick response to changes in flow rate and are well
suited to flow control and batch type applications in addition to flow monitoring. The new four-bladed impeller design is
rugged, non-fouling and does not require custom calibration.
Coupled with the proprietary patented digital detection circuit, the sensor measures flows from under 0.3 feet per second to
over 20 fps regardless of the conductivity or turbidity of the liquid. The standard frequency output produces a low impedance
square wave signal proportional to flow rate that may be transmitted up to 2000 feet without amplification. Models are
available to measure flow in one or both directions.
All SDI insert sensors are mounted on the pipe using a 1 in. tap. As with any insert sensor, a pipe saddle or weld-on fitting is
preferred over a service tee because it causes fewer disturbances to the flow.
MODELS AVAILABLE
Direct insert sensor models are installed in piping configurations that are not in service or under pressure.
Hot tap insert sensor models feature isolation valves and mounting hardware to install or remove the sensor from a pipeline
that would be difficult to shut down or drain. In a true hot tap installation the sensor is mounted in the pipe under pressure
by attaching a service saddle or weld-on fitting to the pipe and mounting the isolating valve and nipple to the threaded
connection. A hole is then cut in the wall of the pipe through the valve using a commercial tapping machine with a 1 in. size
cutter. Once the hole is cut, the tapping machine is removed and the valve is shut. Then the sensor assembly is mounted to
the isolation valve and extended into the pipeline to measure flow.
Even in new construction a hot tap sensor may be appropriate for service considerations.
The small stem diameter allows the sensor to be inserted into the pressurized pipeline by hand without the need for an
installation tool. The mounting hardware holds the sensor firmly in place at the correct depth and alignment.
ELECTRONIC OUTPUTS
Standard Frequency
Sensor output is a pulse proportional to flow. The signal is similar to all 200 Series Badger Meter impeller flow sensors and will
interface with all existing Badger Meter transmitters and monitors. The power supply to the sensor and the output signal from
the sensor are carried on the same two wires. Wire connections are made at screw terminals on removable headers inside the
NEMA 4X housing.
Analog Output
The sensor is also available with a two-wire loop powered 4…20 mA output. The analog output is produced by an on-board
micro-controller for precise, drift-free signals. The unit is programmed from a computer using Windows® based software and
an A-301 connection cable. Units may be pre-programmed at the factory or field programmed. All information is stored in
non-volatile memory in the flow sensor.
Scaled Pulse Output
The scaled pulse is produced by an on-board micro-controller for precise, accurate outputs. This option may be programmed
to produce an isolated dry contact closure scaled to any number of engineering units of measure. Sensors may be preprogrammed at the factory or field programmed using an A-301 connection cable and a Windows based software program.
All information is stored in non-volatile memory in the flow sensor. This is a four-wire option.
Bidirectional Flow, Analog Output
This option provides a programmable 4…20 mA signal proportional to flow rate and a contact closure to indicate the
direction of flow. All programming is accomplished as previously mentioned. The user can program the unit for pipe size, flow
scale and the direction of flow. This is a six-wire option.

Mechanical Installation
Bidirectional Flow, Scaled Pulse Output
This option provides the user with a choice of outputs. In one case the sensor provides an output scaled to the required
number of engineering units on one set of terminals and a contact closure to indicate the direction of flow on another. The
other choice provides two isolated scaled pulse outputs, one for each direction. Programming the output choice, pipe size,
output scale and direction of flow by the user are also accomplished by using a PC with Badger Meter software and A-301
connection cable. This option also requires six wires.

Display Options
All models except the standard frequency output version may also be equipped with a display. Integrated into the NEMA 4
housing, the 8 digit LCD may be programmed to show rate of flow, flow total or toggle between the two. Bidirectional models
also show flow direction.
MECHANICAL INSTALLATION
The accuracy of flow measurement for all insert type flow measuring devices is highly dependent on proper location of the
sensor in the piping system. Irregular flow velocity profiles caused by valves, fittings and pipe bends can lead to inaccurate
overall flow rate indications even though local flow velocity measurement may be accurate. A sensor located in the pipe that
is partially full or where it can be affected by air bubbles, floating debris or sediment may not achieve full accuracy and could
be damaged.
Badger Meter impeller flow sensors are designed to operate reliably under adverse conditions, but the following
recommendations should be followed to provide maximum system accuracy.

Mechanical Installation
• Choose a location along the pipe where there is straight pipe for a distance of 10 pipe diameters upstream and 5 pipe
diameters downstream of the sensor. Pipe bends, valves, other fittings, pipe enlargements and reductions or anything else
that would cause a flow disturbance should not be present in this length of pipe.
• The recommended tap location around the circumference of a horizontal pipe is on top. If trapped air or debris will
interfere, then the sensor should be located around the pipe from the top preferably not more than 45 degrees from
top dead center. The sensor should never be located at the bottom of the pipe, as sediment may collect there. Locations
off top dead 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. Insertion depth is critical to accuracy. The algorithm
used to convert impeller motion into flow was developed through flow tests in an independent calibration laboratory.
The impeller must be located in the same position in the pipe as it was in the calibration test for the impeller frequency to
accurately describe the same liquid velocity. Detailed installation instructions on the following pages include methods for
correct insertion depth.
• Alignment of the sensor is also important. The
15 3/4 in. *
impeller shaft must be perpendicular to the
flow for accuracy. Alignment instructions are
also included on the following pages.
* Pipe Sizes for reference only. Depending on pipe material, tapping
saddle or existing hardware longer sensor length may be required.
Contact factory for more information.

Installation for Direct Insert Models
These instructions are for the installation of flow sensors into piping systems that are not under pressure at the time of
installation. If the line must be tapped under pressure, a hot tap style sensor must be used. See “Installation for Hot Tap
Models” on page 7 for hot tap installation instructions.
The insertion depth and alignment of the sensor are critical to the accuracy of the flow measurement. The impeller must be at
the same location in the pipe as it was during calibration. Badger Meter provides sensors with different stem lengths. Longer
stems are intended for use in larger diameter pipes and shorter stems for use in smaller pipelines. However stem length has
no affect on the operation of the sensor provided that the impeller is positioned correctly in the pipe.
Direct insert models are available in one stem length designated D1. They are intended for nominal pipe diameters from
1-1/2…10 in. However, pipe with extra thick walls, existing linings, or unusual tapping hardware may require longer length
sensors - Consult factory. For larger pipe sizes hot tap style sensors equipped with isolation valves are recommended.
The preferred method of installation is by means of a saddle with a 1in. NPT outlet. On steel pipelines a weld-on type fitting
may be substituted.

2. Remove the sensor assembly from the mounting hardware by loosening the hex
cap over the stem collar and the cover to the mounting adapter and detaching the
assembly. Set aside taking care not to damage impeller/shaft assembly.
3. Attach the pipe thread end of the mounting adapter to the saddle or weld-o-let using
a pipe joint compound and tighten the joint. Do not apply sealing compound to the
top thread of the mounting adapter. It is sealed with an O-ring.
4. The sensor rotor assembly is to be located a xed distance from the center of the pipe.
To position the impeller at this depth, use a reference measurement for the pipe size
and schedule.
a. Look up the pipe size and schedule number in the “Customer Reference Number
Tables” on page 14 and note the Customer Reference Number (Customer Ref #)
OTE:N The Customer Reference Number has been calculated using the
following formula:
Ref # = Insertion Depth + Wall Thickness + Cover Thickness
b. Next, measure from the outside wall of the pipe to the top of the installed
mounting adapter, this is dimension B in Figure 5.
c. Add this number to the reference measurement. The resulting number is
dimension C in Figure 6
Dimension C = Customer Ref # + Dimension B
d. Dimension C is the distance from the recess of the sensor tip to the bottom of the
stem collar. Insert the metal tab of a tape measure into the recess of the flow sensor
tip. Extend the tape up the stem and mark the shaft with a pencil.
e. Slide the collar along the shaft until its bottom surface is at the mark on the stem.
Tighten the cap screw on the collar. When the sensor is reassembled, this will set
the insertion depth of the sensor.
5. Attach the sensor to the mounting adapter by gently pushing the ow sensor into the
C
mounting adapter until the cover touches the mounting adapter. Tighten the cover
against the O-ring seal. This will seal the sensor assembly.
6. Continue to insert the ow sensor stem until the stem collar meets the cover. Thread
the hex cap onto the mounting adapter but do not tighten. Align the ow sensor
with the pipe by using the at cover on the electronics housing as a guide. Place a
straightedge along the cover and rotate the sensor until the straightedge is parallel
with the pipe as shown in Figure 7. Tighten the hex cap over the collar approximately
10 ft-lb. The hex cap holds the sensor alignment but performs no sealing functions.
DO NOT OVER TIGHTEN .

linings or unusual tapping hardware may require longer length sensors. For these, consult the factory.
The preferred method of installation is by means of a saddle with 1in. NPT outlet. On steel pipelines a weld-on type fitting
may be substituted.

3. If pipe is drained, drill a 1-1/8 in. minimum hole into pipe and install
a saddle or welded tting onto the pipe. If pipe is under pressure
a tapping machine will be needed. Install the saddle onto the pipe

4. Attach the tapping adapter, (Badger Meter Part# A-1027) to the top of the valve (make sure O-ring is properly seated in
the O-ring groove in the top of the ball valve assembly). It is recommended at this point that the valve be opened and the
A-1027 be connected to a water or AIR Source to pressure test the saddle and valve threaded joint. Once the pipe is drilled,
any leaks in this area would require that the pipe be drained to repair.
5. Use any tapping machine with a 1 in. MNPT pipe thread, with an arbor less than 1 in. O.D., capable of holding a 1.00 in.
Hole Saw and with at least 7 in. of travel. The SDI ball valve is manufactured oversized with a 1.00 in. bore, and the SDI
sensor is almost interference t requiring that the hole being drilled also be 1.00 in. For this reason, the 7/8 in. drill bit
normally recommended for drilling through a 1 in. ball valve cannot be used.
6. Attach the tapping machine to the tapping adapter. Make sure that all connections and seals are tight.
7. Slowly open the valve by rotating the handle 90° and lower the cutter past the valve ball to the pipe. Drill the 1 in. nominal
hole according to the manufacturer’s instructions.
8. Withdraw the cutter past the valve ball, close the valve and remove the tapping tool.
9. Remove the Badger Meter tapping adapter from the top of the valve.
10. The sensor rotor assembly is to be located a xed distance from the center of the pipe. To position the impeller at this
depth, a reference measurement for the pipe size and schedule is used.
a. Look up the pipe size and schedule number in the “Customer Reference Number Tables” on page 14 and note the
Customer Reference Number (Customer Ref #).
OTE:N The Customer Reference Number has been calculated using the
following formula:
Ref # = Insertion Depth + Wall Thickness + Cover Thickness
b. Next, measure from the outside wall of the pipe to the top of the installed mounting adapter, this is dimension B in
Figure 5 on page 6.

Dimension C = Customer Ref # + Dimension B
d. Dimension C is the distance from the recess of the sensor tip to the bottom of
the stem collar. Insert the metal tab of a tape measure into the recess of the
flow sensor tip. Extend the tape up the stem and mark the shaft with a pencil.
e. Slide the collar along the shaft until its bottom surface is at the mark on the
stem. Tighten the cap screw on the collar. When the sensor is reassembled, this
B
will set the insertion depth of the sensor. Make sure to hold the sensor up tight
against the cover when installing onto the valve, to prevent the possibility of
damaging the impeller by striking the closed ball of the valve.
11. Slide the cover down the stem until it stops.
12. Attach the sensor to the valve by inserting the impeller end of the stem into the
valve until the cover touches the top of the valve. The sensor tip and impeller will
be in the section of the valve above the ball.
13. Tighten the cover against the O-ring in the top of the valve. This will seal the
sensor assembly.
14. Open the ball valve again by slowly rotating the handle 90°. If the cover was not at
the bottom of the sensor stem, water pressure from the pipe would now push it
out until it stops. However, the sensor cannot be ejected from the pipe if the cover
is secured to the valve. Check to make sure all joints are tight.

15. Insert the ow sensor stem into the pipe by pushing against the top of the
electronics housing with a slight twisting motion until the stem collar meets the
cover. The force required to push the sensor into the pipeline is approximately 20%
of the line pressure. Be aware of the close spacing between the diameter of the
ow sensor, the bore of the ball valve and the hole in the pipe. If the sensor stops
or catches before the stem collar meets the cover, apply a gentle rocking/twisting
motion to the sensor to continue its travel.
16. While holding the ow sensor collar against the cover, thread the hex cap onto the
cover to hold the ow sensor in place, but do not tighten.
17. Align the ow sensor with the pipe using the at side cover of the electronics
housing as a guide. Place a straightedge along the cover and rotate the sensor until
the straightedge is parallel to the pipe.
