"FM/CSA" Sensor
Designed for indoor or protected area applications where
intrinsic safety is required and the flow rates are between
0.5-30 feet/second and temperatures are below 221
deg. F. FM/CSA sensors are supplied with 20 feet of
2-conductor 20 AWG shielded U.L. type PTLC 105 deg.
C cable. These sensors must be used with an approved
safety barrier.
Models 228BR, 228CB, 228SS, and 228CS
Sizes of 2” and 2 1/2” are available in this series.
Model 228BR
This model consists of a Model 220BR sleeve and hex
mounting adapter assembly inserted in a 2" or 2 1/2"
bronze tee and preset to a specific height. The 2" size
includes copper solder adapters for mating to copper tub-
ing.
Model 228CB
This model consists of a Model 220BR sleeve and hex
mounting adapter assembly inserted in a 2" or 2 1/2"
Class 150 cast iron tee and preset to a specific height.
Model 228CS
This model consists of a Model 220SS sleeve and hex
mounting adapter assembly inserted in a 2" or 2 1/2"
Class 150 cast iron tee and preset to a specific height.
Model 228SS
This model consists of a Model 220SS sleeve and hex
mounting adapter assembly inserted in a 2" 316 stainless
steel tee and preset to a specific height.
Model 250BR
These models combine a PPS
electronics package
inserted in a 1/2”, 3/4", 1”, 1 1/4”, and 1 1/2” proprietary
cast bronze pipe tee with threaded NPT connections.
InTROduCTIOn
Used in conjunction with any Badger Meter Impeller
flow monitor or transmitter, Badger Meter non-magnetic
flow sensors provide an accurate reading of the 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.
Electronic Types
Badger Meter provides several basic sensor configura-
tions using the same impeller element. This allows for a
wide range of applications and pipe sizes. Sensors are
normally supplied with 20 feet of 2-conductor 20 AWG
shielded U.L. type PTLC 105 deg. C cable. Optional sen-
sors designated with the prefix "IR" feature two single
conductor 18 AWG solid copper wire leads 48 inches
in length with U.L. Style 116666 direct burial insulation.
These IR models are used in below grade applications
such as irrigation, municipal, and groundwater monitoring.
All Series 200 sensor electrical components are self-
contained. Pressure/temperature ratings for the various
models are contained in the Specifications section of this
manual. These models can be further described as fol-
lows:
"Standard" Sensor
Designed for indoor or protected area applications such
as HVAC, pump control, and industrial process monitoring
where the flow rates are between 0.5-30 feet/second and
temperatures are below 221 deg. F. Standard sensors
are supplied with 20 feet of 2-conductor 20 AWG shielded
U.L. type PTLC 105 deg. C cable.
"IR" Sensor
Designed for below grade applications such as irrigation,
municipal, and groundwater monitoring where the flow
rates are between 0.5-30 feet/second and temperatures
are below 180 deg. F. IR sensors are supplied with two
single conductor, 18 AWG solid copper wire leads 48
inches in length with U.L. Style 116666 direct burial insu-
lation.
