Materials ~ See Options
The 200 Series 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 can be provided by the LCD flow monitor supplied or from a clean DC Supply. The impeller bearing assembly, shaft and O-rings are replaceable in the field. Badger Meter 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 waterborne 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.
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 more than 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…30 feet/second (± 4.0 percent of reading within calibration range).
MODEL 220PVS SENSOR
The 220 PVCS flow sensor is an insertion style flow sensor constructed of non-metallic materials for all wetted parts. These sensors are designed for service in corrosive fluids. The metallic trim, in non-wetted areas, is 316 stainless steel. The sensor mounts in a 2" NPT thread and may be attached to the pipe with a saddle or other types of mounting hardware. The 220 PVCS sensor features a six bladed impeller design with a proprietary, non-magnetic sensing mechanism. The impeller shape coupled with the absence of magnetic drag provides consistent accuracy and repeatability throughout the flow range of the sensor. As the liquid turns the impeller, a low impedance signal is transmitted with a frequency proportional to the flow rate. This signal can travel up to 600 m (2000 feet) between the sensor and the display unit without the need for amplification. The sensor is supplied with 6 m (20 feet) of shielded two wire cable.
