FLOWLINE switch-™ lu10 level switch

flowline-Switch-Tek-LU10-Ultrasonic-Liquid-Level-Switch

CSA approved for use in hazardous locations, the intrinsically safe ultrasonic liquid level switch provides high or low liquid level detection of chemical, solvent or low viscosity petroleum based liquids with a 1A relay output. Media examples include hydrochloric acid, acetone and diesel fuel oil. The submersible PP or PFA level switch sensor is universally mounted through the tank wall or inside the tank, and connected to a PLC or relay controller.

flowline smart tek lu10 features:

  • CSA approved intrinsically safe for use in hazardous environments
  • Submersible PP or PFA Teflon® sensor and cable for corrosive liquids
  • 60VA SPST relay selectable NO or NC via power supply wiring polarity
  • Compatible with Smart Trak and Switch-Pak installation fittings

compatible products:

Switch-Pro, Remote Level Controller. The general purpose remote level controller is offered in three configurations for pump and valve control. The LC40 accepts one level sensor input and provides one 10A relay. The LC41 accepts two level sensor inputs and provides one latching 10A relay for automatic fill or empty control. The LC42 accepts three level sensor inputs with one latching 10A relay output for automatic fill or empty control, and a second non-latching 10A relay for high or low level alarm. For field mount installation, add a single or dual indicator NEMA box.


Switch-Pro, Compact Level Controller. The general purpose compact level controller is offered in two configurations for pump and valve control. The LC10 accepts one level sensor input and provides one 16A relay for high level control or low level control. The LC11 accepts two level sensor inputs and provides one latching 16A relay for automatic fill or empty control. The optional flash alarm brings attention to alarm conditions. Package this level controller with our liquid level switch sensors and fittings
