Badger Meter Series 735 Sensors - Manual (Page 3)

INTRODUCTION
Used in conjunction with any Badger Meter 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. The impeller bearing assembly, shaft and o-rings are replaceable
in the field.
The Series 735 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.
ELECTRONIC TYPES
Sensors are normally supplied with two single-conductor 18 AWG solid copper wire leads 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 735 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.
IR Sensor
Designed for below grade applications such as irrigation, municipal, and groundwater monitoring where the flow rates are
between 2...20 feet/second and temperatures are below 110° F. IR sensors are supplied with two single conductor, 18 AWG
solid copper wire with U.L. Style 116666 direct burial insulation.
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" BSP threaded adapters also available.
