FlowLine Liquid Level Switches

Flowline-logo.JPG (22143 bytes)

FlowLine offers the industry's most complete line of engineered plastic level switches, relay controllers and installation fittings. To ensure broad and reliable application coverage, they have developed an advanced range of complimentary technologies including tuning fork, ultrasonic, RF capacitance, optic and buoyancy devices. The modular product architecture allows each switch technology to be packaged with a wide variety of relay controller and fitting accessories.

Each system will require a switch(s), a controller and may included switch mounting (as required).

FL-SensorA.jpg (31761 bytes) Ultrasonic Switch - An ultrasonic switch is installed through the side wall of the tank for a high or low-level switch application. The LU10 series ultrasonic switch provides reliable detection of light to medium coating or scaling type liquids including printing ink, lubricating oil and paint. Not recommended for heavy coating liquids or bubbles. The switch is constructed of rugged PP or PFA materials and features a solid state FET switch output for interface with a PLC or relay control device.  Instruction manual
FL-SensorB.jpg (31861 bytes) Buoyancy Switch - Three buoyancy switches are packaged with Smart Trakô for an automatic fill or empty application with a high level alarm. The LV10 series vertical buoyancy switch provides reliable detection of non-coating or scaling type liquids including organic solvent, acetic acid and process water. Two versions are available - one for clean liquids and one for dirty, non-coating liquids.  The switch is constructed of rugged FP and features a reed switch output for interface with a PLC or relay control device.  Instruction Manual
FL-SensorC.jpg (31448 bytes) Intrusive RF Capacitance Switch - An RF capacitance switch is packaged with Switch Pakô for a high level switch application with integral flash alarm. The LP10 series intrusive RF capacitance switch provides reliable detection of conductive, light coating or scaling type liquids including wastewater, hydrogen peroxide and glycol solution. The switch is constructed of rugged PP and features a solid state FET switch output for interface with a PLC or relay control device.  Instruction manual.
FL-SensorD.jpg (31893 bytes) Tuning Fork Switch - A tuning fork switch is packaged with a compact relay controller and installed through the side wall of the tank for a high or low level switch application. The LZ10 series tuning fork switch provides reliable detection of more challenging coating or scaling type liquids including sodium hydroxide, brine and copper sulfate solution. The switch is constructed of PP/Ryton and features a solid state FET switch output for interface with a PLC or relay control device.

FL-SensorE.jpg (31526 bytes) Non-intrusive RF Capacitance Switch - An RF capacitance switch is installed against the side wall of the tank for a high or low level switch application. The LF50 series non-intrusive RF capacitance switch provides reliable detection of conductive, non-coating or scaling type liquids including nitric acid, ultra pure and process water. The switch is constructed of rugged polysulfone and features a solid state FET switch output for interface with a PLC or relay control device.  Instruction Manual

Note regarding application of the above switch:  Switch selection and application is dependent upon the condition of the liquid - coating, foaming, dirty, non-conductive natures of the liquid are all considerations.  Non-intrusive, ultra-sonic detectors are available to deal with almost any liquid except gasses or vapors. Please contact us for recommendations prior to final selection.
Level switches are mounted using the 3/4" NPT connection or using FlowLine Smart Trak™ or Switch Pak™ mounting systems.
