200 Series
Plastic Tee Type Flow Sensors
by Data Industrial
Owner's Manual
Introduction
Used in conjunction with any Data Industrial flow monitor or
transmitter, Data Industrial non-magnetic 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. Power to operate the sensor is provided by
the flow monitor. The impeller bearing assembly, shaft and O-rings 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 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.
Electronic Types
Data Industrial provides several basic sensor configurations using the same impeller element. This allows for a
wide range of applications and pipe sizes. Sensors are normally supplied with 20 feet of 2-conductor 20 AWG
shielded U.L. type PTLC 105°C cable. Optional sensors designated with the prefix "IR" feature two single
conductor 18 AWG solid copper wire leads 48 inches in length with U.L. Style 116666 direct burial insulation.
These IR models are used in below grade applications such as irrigation, municipal, and groundwater monitor-
ing. All 200 series sensor electrical components are self-contained. Pressure/temperature ratings for the
various models are contained in the
Specifications
section of this manual. These models can be further de-
scribed as follows:
"Standard" Sensor
Designed for indoor or protected area applications such as HVAC, pump control, and industrial process monitor-
ing where the flow rates are between 0.5-30 feet/second and temperatures are below 221°F. Standard sensors
are supplied with 20 feet of 2-conductor 20 AWG shielded U.L. type PTLC 105°C cable.
"IR" Sensor
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 180°F. IR sensors are supplied with two
single conductor, 18 AWG solid copper wire leads 48 inches in length with U.L. Style 116666 direct burial
insulation.
