Designed for a broad spectrum of industrial fluids

• Pure water
• Tap water
• Sea water
• Cooling tower water
• Glycol solutions
• Acids
• Bases
• Hydrocarbons
• Ketones
• Lubricating oils
• Gasoline
• JP-4
• Plating solutions

• Responds to fluid flow only, independent of line pressure and temperature.
• Max flow may be five times normal flow.
• Positive stop eliminates fatigue effects of turbulence, vibration and flow surge on flow detecting element.
• Quick response.
• Small size and low profile provides easy mounting in crowded installations.
• Very low pressure drop – typically less than 1.0 psig at normal flow rate.
• Line pressure to 250 psig at room temperature.
• Temperature to 200°F continuous.
• Switches 5 VDC to 240 VAC.
• Switches resistive and light inductive loads.
• Switches Dry Circuit Computer/PLC inputs.
• Switch employs magnetic coupling.
