simple to install with time honored reliable performance, signet 2536 rotor-x paddlewheel flow sensors are highly repeatable, rugged sensors that offer exceptional value with little or no maintenance. the model 2536 has a process-ready open collector signal with a wide dynamic flow range of 0.1 to 6 m/s (0.3 to 20 ft/s). the sensor measures liquid flow rates in full pipes and can be used in low pressure systems.
the signet 2552 metal magmeter from georg fischer features all-stainless steel construction. the pvdf nosepiece and fpm o-rings are the only other wetted materials. the 2552 installs quickly into standard iso 7- r 1 ¼ or iso 7- r 1 ½ (1¼ in. or 1½ in. npt) pipe outlets, and is adjustable to fit pipes from dn50 to dn2550 (2 to 102 inches). two sensor lengths allow maximum flexibility to accommodate a variety of hardware configurations, including ball valves for hot-tap installations.
