Gems Sensors & Controls 捷迈 29609 流量计

Standard FS-550 switches sense liquid flow in either direction to monitor flow\/no-flow conditions. The paddle is trimmed during installation to permit switch actuation at the desired flow rate. As flow increases, the paddle pivots to move out of the liquid path, producing less than 200 MB of pressure drop regardless of pipe size. Using Gemsâ„¢ Safe-Pak® Relays and Barriers, these switches provide automatic flow \/ no flow interlock and are intrinsically safe without explosion proof housing and piping.• Engineered for positive liquid flow detection at pressures to 138 bar (2000 psig) ,• Unique, patented cam design assures low-pressure drop and does not require bellows, seals or mechanical linkages ,• Minimum inline restriction, Paddle pivots to move out of liquid path with increasing flow ,• Pipe line size: 1 1\/4 Inch and up ,• Primary construction material: Stainless steel or brass ,• Setting Type: Fixed• Compressors ,• Heat Exchangers ,• Turbines ,• Engine ,• Boilers ,• Chillers ,• Valves ,• Pumps ,• RegulatorsMedia Monitored = LiquidDevice Type = PaddleMinimum Flow Rate = 15 gal\/minMaximum Flow Rate = 52 gal\/minPipe Diameter Range = 1 inConnection Type = 1 NPT MaleMaximum Pressure = 138barMaterial = BrassMinimum Operating Temperature = -34.4°CMaximum Operating Temperature = +148.9°C
