Flowline® level sensors/switches provide ultrasonic, vibrating fork, capacitive and buoyancy sensing technologies for a variety of applications. Intrinsically safe Ultrasonic Level Switches provide reliable liquid level detection of chemical, solvent, hydrocarbon and petroleum based liquids. Use the Vibration Point Level Switch for level detection of liquids with light to medium coating, scaling or foaming characteristics. The Capacitance Level Switch is ideal for water based conductive liquids with light coating, crystalizing or scaling characteristics. The Buoyancy Level Switch is ideal for relatively clean water and chemical solutions. Flowline level controllers are an easy-to-configure solution for controlling valves and pumps for automatic empty/fill of tanks as well as high and low level alarming. Flowline level sensors and level controllers start at $102.00 .
