Plastic Tee Type Flow Sensor
"FM/CSA" Sensor
Designed for indoor or protected area applications where intrinsic safety is required and the flow rates are
between 0.5-30 feet/second and temperatures are below 221°F. FM/CSA sensors are supplied with 20 feet of
2-conductor 20 AWG shielded U.L. type PTLC 105°C cable. These sensors must be used with an approved
safety barrier.
"Magnetic" Sensor
Designed for use with the Series 1400 battery powered flow monitor in above or below or grade applications
such as irrigation, municipal, and groundwater monitoring where the flow rates are between 1-30 feet/second
and temperatures are below 221°F.
Model 228PV (Formerly 220P)
These models feature a modified
PVC tee with solvent weld socket
end connections, and a removable,
PPS or PVDF sensor insert. Sizes of
1 1/2”, 2”, 3” and 4” are available.
Model 228PD and 220PF

Mechanical Installation
General
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, pipe bends, etc.
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. Data Industrial
flow sensors are designed to operate
reliably under adverse conditions,
but the following recommendations
should be followed to ensure
maximum system accuracy:
1) Choose a location along the pipe where 10 pipe diameters upstream and 5 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.
2) 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.
