Paddlewheel Flow Sensors is highly repeatable, reliable performance, rugged sensors & little or no maintenance. The Model ATN400 has open collector signal output (sink) and has a wide dynamic flow range of 0.5 to 5 m/s ( 0.3 to 20 ft/s ). The sensor use to measures liquid flow rates in full pipe. Sensors can be installed in 15 NB to 300 NB (0.5 to 12 in.) Line size. To install this sensor in process line, we offer different types of T-fitting. These T-fittings, which include “T” with threaded & flange end, weld adapter and block design to seat the sensor to the proper insertion depth into the process flow.
