Badger Meter PVC Tee - 1 1/2 to 4"" - Manual (Page 3)

Installation & Operation Manual
INTRODUCTION
Used in conjunction with any Badger Meter Impeller flow monitor or endpoint, Badger Meter non-magnetic Impeller 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 Impeller 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 configurations 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° C cable. Optional sensors 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 Badger Meter Series 200 sensor electrical components are
self-contained. Pressure/temperature ratings for the various models are contained in "SPECIFICATIONS" on page 10. These
models can be further described as follows.
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° F. Standard sensors are supplied with 20 feet of
2-conductor 20 AWG shielded U.L. type PTLC 105° 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° 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 insulation.
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 140° F. CSA sensors are supplied with 20 feet of 2-conductor 20 AWG
shielded U.L. type PTLC 105° C cable. These sensors must be used with an approved safety barrier.
Model 228PV (Formerly 220P)
These models feature a modified PVC tee with solvent weld socket end connections, and a removable, PPS or PVDF sensor
insert. Sizes of 1-1/2", 2", 3" and 4" are available.
