Badger Meter Irrigation Sensors - 1/2 and larger" - Manual (Page 6)

Series 200 Flow Sensors
1. Set one set of 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. Then adjust the other
two sets of hex/jam nuts 1-1/2 inches below the first
jam nut to allow clearance for the tool top yoke.
2. Remove the tool split ring and clevis pin and slide
tool bottom yoke into the groove on the sensor hex
mounting adaptor and secure by replacing the clevis
pin and split ring.
3. Mark sleeve 2-3/4 inches from impeller end of metal
sleeve. This mark is a stopping point to insure that
impeller/bearing is not damaged. Open the bleed
petcock valve on the hex adapter to relieve the
pressure resulting from the sensor tube insertion.
Carefully hand insert the Badger Meter hot tap
flow 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 (approx. 1 1-1/4 inches). 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.
4. Fully extend tool by turning drive nut
counterclockwise with a 15/16 inch socket or box
wrench (not provided) until drive nut contacts tool
and slide the positioning collar into the tool top yoke.
5. Rotate tool so the threaded rod with the adjusted
hex/jam nuts is centered in the top yoke of hot tap
tool.
6. Rotate sensor sleeve so positioning collar holes align
with the threaded rods and flow direction label is in
general direction making sure the positioning collar is
located in the recessed area of the top yoke. Slide the
top yoke of the tool over the positioning collar and
secure by tightening the two thumbscrews on the top
of the yoke.
7. Close the bleed petcock and slowly open the isolation
valve. Slowly turn the 15/16 inch drive nut clockwise
to insert the sensor tube assembly through the
valve and into the pipeline. Carefully guide the three
threaded studs of the hex mounting adapter through
the holes of the sensor positioning collar. Carefully
lower the sensor until the positioning collar contacts
the hex nut preset for the correct depth adjustment.
Install the three lock nuts onto the threaded rods,
tightening only the lock nut on the threaded rod with
the preset hex/jam nut; then, bring the two remaining
lock nuts down until they just contact the positioning
collar. Do not tighten at this time
8. Remove the Model HTT Insertion/Removal Tool, by
loosening the two thumbscrews, removing the clevis
pin and then sliding the insertion tool off the sensor.
Then bring the two remaining sets of hex/jam nuts up
to the underside of the positioning collar, and tighten.
9. Align the sensor by first loosening the two set screws
in the side of positioning collar with a 3/32 inch Allen
wrench. Then align the sensor sight holes along the
pipe axis using the alignment rod provided in the
sensor installation kit. Ensure that the flow label arrow
on the sensor matches the liquid flow direction inside
the pipe. Tighten the positioning collar set screws.
Note: As a backup to the flow label arrow, there is
a small hole located beside the sight hole on the
upstream side of the sensor.
ELECTRICAL INSTALLATION
"STANDARD" SENSORS
1. The metal collar on the top of the 220 sensors or an
optional conduit cap on the Series 250 sensors will
accept 1/2 inch threaded conduit fittings.
2. Route the cable from the sensor to a Badger Meter
flow monitor/transmitter. The cable may be extended
up to 2000 feet, using 2-conductor shielded 20 AWG
or larger stranded copper wire. Be sure to leave
enough flexibility in the cable or conduit to allow for
future service of sensor, if necessary.
3. When connecting to a Badger Meter flow monitor/
transmitter, locate the section of terminal strip on the
monitor labeled “SENSOR INPUT” or “SENSOR”.
Connect the red wire to “ IN”, "SIGNAL(+)" or
"SIGNAL" terminal and the black wire to “GND",
"SIGNAL(-)”, or "COM" terminal and the shield drain
wire (if applicable) to “SLD”.
4. When interfacing with other equipment, consult
manufacturer for input designations. The signal wave
forms and power requirements are as shown in the
specifications section. Refer to Technical Bulletin
DTB-058 at www.badgermeter.com.
ELECTRICAL INSTALLATION "IR"
SENSORS
The sensor leads are supplied with watertight caps over
the ends. See Application Note DAB-031 and Technical
Bulletin DID-003 at www.badgermeter.com.
1. DO NOT remove the plastic caps from the sensor
leads until ready to splice.
2. Use a twisted pair cable suitable for direct burial to
connect the sensor to the transmitter, monitor, or
controller. Multi-pair telecommunication cable or
direct burial cables may be used.
3. Make a water tight splice. Two part epoxy type
waterproof kits are recommended. Be sure the epoxy
seals the ends of the cable jacket.
4. Make sure the epoxy is hardened before inverting the
splice or dropping it in standing water.
