Badger Meter 228 Data sheet
Flow Sensors
Series 228PV PVC Tee Type Flow Sensors 1-1/2…4 inch
DESCRIPTION
Used in conjunction with any Badger Meter® flow monitor or
transmitter, Badger Meter non-magnetic flow sensors provide an
accurate reading of the rate of liquid flow and total accumulated
flow. The available sensor models cover applications for a wide
range of pipe sizes and pressure/temperature specifications.
The flow sensors generate a frequency 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 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.
Series 228PV
These models feature a modified PVC tee with solvent weld socket
end connections, and a removable PPS or PVDF sensor insert. Sizes
include 1-1/2, 2, 3, and 4 inch.
ELECTRONIC TYPES
Badger Meter provides several basic sensor configurations,
using the same impeller element, allowing 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. All Series 200 sensor electrical components
are self-contained. Pressure/temperature ratings for the models
are contained in the specifications section of this document. These
models are further described as follows.
Standard Sensor
These sensors are designed for indoor or protected area
applications such as HVAC, pump control, and industrial process
monitoring where flow rates are between 0.5…30 feet/second
and temperatures are below 140° F (60° 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
These 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 140° F (60° 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.
