microtuf - Model FS42CS -Basic Mass Flow Switch
Thermal Differential Mass Flow Switch for the detection of the mass flow rate of liquids and gases. Wide operating temperature range -100°F to +850°F (-70°C to +458°C). Wide flow range of .01 to 5 feet per second (fps) in oil, 2.5 fps in water and .1 to 500 fps in gases. Two year workmanship warranty. Removable Plug-in electronics. Free of all moving parts that can stick, coat or fail. Fast response time of .5 to 10 seconds depending on the media. Self heating sensor design improves repeatability. No separate heater to fail or slow response time. Optional Glass window (XW).
