Introduction

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-blade 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 supplied with two single-conductor 18 AWG solid copper wire leads 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 735 sensor electrical components are self-contained. See "Specifications" on page 10 for pressure and
temperature ratings.

IR Sensor

Designed for below grade applications such as irrigation, municipal, and groundwater monitoring where the flow rates are
between 2…20 ft/sec. and temperatures are below 110° F. IR sensors are supplied with two single conductor, 18 AWG solid
copper wire with UL Style 116666 direct burial insulation.

Series 735

These models feature a modified PVC tee with solvent weld socket end connections, and a removable PPS sensor insert. Available
sizes are 1/2 in. (12.7 mm), 3/4 in. (19.05 mm) and 1 in. (25.4 mm). BSP threaded adapters are available.

MECHANICAL INSTALLATION

DEPRESSURIZE AND VENT PIPING SYSTEM PRIOR TO ANY INSTALLATION OR MAINTENANCE OF THE FLOW SENSOR.

The accuracy of flow measurement for all flow measuring devices is highly dependent on proper location of the sensor in the
piping system. Irregular flow velocity profiles caused by valves, fittings, and pipe bends can lead to inaccurate overall flow
rate indications, even though local flow velocity measurement may be accurate. A sensor located in the pipe where it can be
affected by air bubbles, floating debris or sediment may not achieve full accuracy and could be damaged. Badger Meter flow
sensors are designed to operate reliably under adverse conditions, but the following recommendations should be followed to
ensure maximum system accuracy:

• Choose a location along the pipe with ten pipe diameters upstream and five pipe diameters downstream of the sensor
provide no flow disturbance. Pipe bends, valves, other fittings, pipe enlargements and reductions should not be present in
this length of pipe.

• The preferred location for the sensor around the circumference of a horizontal pipe is on top. If trapped air or debris will
interfere, then the sensor should be located further around the pipe from the top but not more than 45 degrees from
top dead center. The sensor should never be located at the bottom of the pipe, as sediment may collect there. Locations
off top dead center cause the impeller friction to increase, which may affect performance at low flow rates and increase
wear. Any circumferential location is correct for installation in vertical pipes. Rising flow preferred to reduce effects of any
trapped air.
