Single Channel Mass Flow - Model FS 4200
microtuf ®

 

Main Feature

• 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.
• 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.
• CE, CENELEC and CSA Approved.
