Series 200
Insertion Flow Sensor
DESCRIPTION
The Data Industrial® Series 200 flow sensors by 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 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 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 2000 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 Belden type 9320 two-conductor shielded cable.
MODEL 220BR (BRASS) AND
220SS (STAINLESS STEEL) SENSORS
The 220BR and 220SS sensors are used in most general flow
measuring applications in metallic or non-metallic pipes. The
sensor mounts in a 2-inch NPT pipe saddle or Threadolet®
for installation in pipe sizes from 3 inches to over 40 inches.
Positioning nuts on the three threaded retaining rods allow the
sensor to be accurately positioned to a standard insertion depth of
1-1/2 inches into the pipe. When this insertion depth is maintained,
and there is at least 10 upstream and 5 downstream diameters of
straight uninterrupted flow, an accuracy of +/-1 percent of full scale
can be obtained from flow velocities of 0.5 to 30 feet/second (± 4.0
percent of reading within calibration range).
The Badger Meter 220PVS flow sensor is an insertion style flow
sensor will all wetted parts constructed of non-metallic materials.
These sensors are designed for service in corrosive liquids. The
metallic trim, in non-wetted areas, is 316 stainless steel. The sensor
mounts in a 2-inch NPT thread and may be attached to the pipe
with a saddle or other types of mounting hardware.
