Series 228
Metallic Tee and Small Pipe Tee Type Flow Sensors

OVERVIEW
The Data Industrial Series 228 flow sensors from Badger Meter
feature a six bladed impeller design with a proprietary
non-magnetic sensing mechanism. The forward swept impeller
shape provides higher, more consistent torque than four bladed
impeller designs and is less prone to be fouled 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. This is especially true where the impeller
is exposed to metallic or rust particles found in steel or iron pipes.
As the liquid flow turns the impeller, a low impedance square wave
signal is transmitted with a frequency proportional to the flow
rate. The signal can travel up to 2,000 feet between the flow sensor
and the display unit without the need for amplification. All sensors
except irrigation versions are supplied with 20 feet of 2-conductor
20 AWG shielded UL type PTLC 105°C cable.

SERIES 228 TEE SENSORS
The tee mounted flow sensors consist of a standard 220BR or 220SS
mounted in a 2 inch or 2.5 inch tee.
