Introduction

 

Used in conjunction with flow monitors or transmitters, Rain Bird non-magnetic flow sensors manufactured by Data 
Industrial provide accurate readings 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. 

The flow sensors generate a frequency which is proportional to flow rate. An internal preamplifier allows the pulse 
signal to travel up to 3000 feet without further amplification. Power to operate the sensor is provided by the flow 
transmitter. The impeller, shaft, O-rings, and impeller bearings are replaceable in the field.

 

Data Industrial 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 other 
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 digital 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.

 

Sensor Types and Size Selection 

Rain Bird provides several basic sensor configurations using the same impeller element. This allows for a wide 
range of applications and pipe sizes. Sensors are supplied with two single conductor 18 AWG stranded copper 
wire leads 48 inches in length with U.L. Style 1056 direct burial insulation. These sensors may be used in below 
grade applications in meter pits of valve boxes. All sensor electrical components are self-contained. Pressure and 
temperature ratings for the various models are contained in the Specifications section of this manual. These 
models are further described one the following pages.
