3) Clean O-rings and flow sensor sleeve, and lightly
lubricate O-rings with silicone grease from the packet
provided or some other acceptable lubricant. Take care
not to get grease on the impeller or bearing.
4) Insert the flow sensor into the 2 inch NPT adapter so
that the mounting holes in the positioning collar fit over
the studs on the adapter. 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 firmly against the upper adjusting nuts to secure
them for future removal of the sensor for inspection or
service.
Alignment of Flow Sensor
1) Loosen positioning collar set screws with a 3/32 inch
Allen wrench. Place the alignment rod through the sight
holes in the flow sensor. Refer to Figure 2. Using the
alignment rod as a guide, align the flow sensor so that
the flow label arrow matches pipe flow direction and so
that the alignment rod is exactly parallel to the pipe. This
procedure aligns the impeller directly into the fluid flow.
2) As a backup to the flow arrow label, there is a small hole
next to the larger sighting hole of the upstream side. With
a 3/32 inch Allen wrench, tighten positioning collar set
screws.
3) Double check that the sighting holes in the sleeve are
parallel down the pipe and that the flow arrow label
matches pipe liquid flow direction.
4) Cable routing: The positioning collar is threaded for
connection of a standard 1/2 inch electrical conduit (flex
cable) or a wire strain relief. Route cable as required.
Be sure to leave enough flex in cable or conduit to allow
future removal of sensor for service or cleaning if neces-
sary.
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 Badger
®
Series 200 hot tap sensors are designed
to be installed either in a depressurized pipe by hand or
“Hot Tapped” into a pressurized pipeline. Both installation
procedures are listed in this installation and operation
manual. If there is the slightest possibility that the pipe could
be full or pressurized, FOLLOW THE INSTALLATION FOR
PRESSURIZED PIPE.
Refer to Figure 3 for location or identification of the various
parts described in the following procedures.
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 from the inside wall of the pipe. In order 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, weld-o-lets, etc.
Depth setting is accomplished by positioning the hex nuts 14
7/8 inches minus the thickness of the pipe, from the outside
diameter of the pipe. For example, measure the wall thick-
ness of the pipe from the coupon removed when the 1 7/8
inch hole was cut into the pipe. If the pipe was 1/8 inch thick,
subtract 1/8 inch from 14 7/8 inch, or position the nuts 14 3/4
inch from the outside diameter of the pipe. This will allow the
16 3/8 inch sensor to protrude 1 1/2 inch into the pipe.
Apply anti-seize thread lubricant, supplied with the sen-
sor, to the threaded studs of the mounting adaptor.
The alignment of the impeller with the flow in the pipe is ac-
complished by aligning 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. To adjust, loosen the
two set screws in the positioning collar with a 3/32 inch Allen
wrench provided in the Series 200 hot tap installation kit.
Slip one end of the 1/4 inch x 18 inch steel rod (also sup-
plied in the installation kit) through the holes in the sensor
tube. Rotate the sensor tube until the rod is centered on the
pipe. Ensure the flow label “Arrow” on the sensor matches
