HIGH PRESSURE PADDLEWHEEL FLOW SENSOR – FLS F3.20
FLS F3.20 is a paddlewheel flow sensor suitable for system at high pressure and at critical temperature. F3.20 is designed for use with every kind of solid-free liquids in compliance with chemical compatibilities of wetted materials. First quality materials used, as SS for body/shaft and Halar® for rotor, grant high mechanical performances and an appreciated reliability. Sensor needs a very limited maintenance and, in those cases, it’s easy to perform due to a 4 screws system and to a graphite flat gasket.F3.20 sensor is available for connection to FLS monitors and for PLC connection directly .SS weld on adapter is available for sensor installation on pipe range from 1 1⁄2” to 8”(DN40 to DN200).
