Gems Paddle Type Flow Switches
For Flow/No-Flow Detection in Large Line Sizes
Engineered for positive liquid flow detection at pressures up to 2000 psig (138 bar)
Unique, patented cam design assures low pressure drop and does not require bellows, seals, or mechanical linkages
Minimum in-line restriction; paddle pivots to move out of liquid path
Typical Applications:
Assure flow and/or leak detection in large, high pressure lines in:
Compressors • Heat Exchangers • Turbines • Engines • Boilers • Chillers
Protect high or low pressure pumps from cavitation, sense critical reverse flow and protect:
Valves • Pumps • Regulators
