Series 200 Sensor - 3" and larger

Series 200 Insertion Flow Sensors

The Data Industrial flow sensor features a six bladed impeller design with a proprietary, non magnetic sensing mechanism. The forward swept impeller shape provides higher, more constant 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 rates. This is more important where the impeller may exposed to metallic or rust particles found in steel or iron pipes. As liquid flow turns the impeller, a low impedance 8VDC square wave signal is transmitted with a frequency proportional to the flow rate. This signal can travel up to 2000' between the sensor and the display unit without the need for amplification. All the sensors are supplied with 20' of Belden type 9320 (two conductor shield) cable.

Model 220B (Brass) and 220SS (Stainless Steel) Sensor

The Model 220B (Brass) and 220SS (Stainless Steel) sensors are used in most general flow measuring applications in metallic, non metallic, or PVDF Pipes.

220SS Insertion Flow Sensor

The sensor mounts in a 2" NPT pipe saddle or Thredolet® for installation in pipe sizes from 2 1/2 " to over 40". Positioning nuts on the three threaded retaining rods allow the sensor to be accurately positioned to the standard insertion depth of 1 1/2 inches into the pipe. When the insertion depth is maintained, and there is at least 10 upstream and 5 downstream diameters of straight uninterrupted flow, an accuracy of +/- 1% of full scale can be obtained between flow velocities of 1 to 30 feet/second.

Hot Tap Sensors Models 225 and 226

The Hot Tap sensor Series features an elongated sensor, special mounting adapter, pipe nipple, and isolation valve, to allow the non magnetic impeller sensor to be installed into a pressurized pipe while the pipe is in service. This is accomplished by first attaching a saddle or Thredolet® to the pipe and screwing the nipple and isolation valve into the saddle or Thredolet fitting. A hole is then drilled through the pipe using a commercial tapping machine, When completed the tapping apparatus is removed, the isolation valve is closed, and the sensor is installed.

The Hot Tap Sensor is also recommended for any application where it would be difficult to shut down or drain the pipeline to remove the sensor for service. The overall length of the sensor is 18 inches (457mm).

Model 220PVCS Insert Flow Sensor

The Data Industrial 220PVCS 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 liquids. 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 220PVCS 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 8 VDC square wave pulse is transmitted with a frequency proportional to the flow rate. This signal can travel up to 2000 feet between the sensor and the display unit without the need for amplification. The sensor is supplied with 20 feet of shielded two wire cable.
