735 Series Plastic Tee Type Impeller Flow Sensor
OVERVIEW
Used in conjunction with any Badger Meter flow monitor or
transmitter, 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 2,000 feet without further amplification. The impeller bearing
assembly, shaft and o-rings are replaceable in the field.
The 735 Series Impeller flow sensors feature a four-bladed impeller
design, using a proprietary, non-magnetic sensing technology.
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.

MODEL 735PV
These models feature a modified PVC tee with solvent weld socket
end connections, and a removable, PPS sensor insert. Available
sizes include 1/2”, 3/4”, and 1”. Threaded BSP adapters also available.
