Introduction
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 (610 meters) 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 .
This manual provides instructions for the Series 228PV tee type impeller flow sensor .
CERTIFICATIONS
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 (6 meters) of 2-conductor 20 AWG shielded UL type
PTLC 221° F (105° C) cable . Optional sensors designated with the prefix IR feature two single-conductor, 18 AWG solid copper
wire leads 48 inches (122 cm) in length with UL 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
. These models are further described as follows .
Standard Sensor
Standard sensors are 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 (105° C) . Standard
sensors are supplied with 20 feet (6 meters) of 2-conductor 20 AWG shielded UL type PTLC 221° F (105° C) cable .
IR Sensor
IR sensors are 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 (82° C) . IR sensors are supplied with two
single-conductor, 18 AWG solid copper wire leads, 48 inches (122 cm) in length, with UL Style 116666 direct burial insulation .
Model 228PV
The model 228PV features 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 inches are available .
