Level controllers provide fail-safe control of pumps or valves. General-purpose point level controllers are available with discrete I/O for alarms, pump and valve control. Models with analog I/O offer more accurate real-time level monitoring and control. Conductive level controllers detect and adjust levels of conductive liquids in dual-probe pump-up or pump-down applications.

Level Controllers
Category Selection
Integrated level controllers can sense level and operate alarms, pumps, valves and other industrial equipment.
Level controllers from Flowline include the Switch-Pro™ and the DataPoint™ general-purpose level controllers.
Prosense CLC series conductive level controllers are purpose-built for detecting and controlling the level of conductive liquids in fill or drain applications.

Switch-Pro™ Remote Level Controllers
The Switch-Pro™ series is available in three discrete sensor input configurations for alarms, pump and valve control.
- Fail-safe relay control of pumps or valves with 0-60 second delay
- LED indicators for sensor, power and relay status
- 35mm DIN rail mount or panel mount polypropylene (PP) enclosure with removable terminal strips
- Invert switch changes relay state from NO to NC without rewiring
- Mounts easily in control panel
- Connects to any Flowline level switch
- Interfaces directly with any horn, buzzer, valve, etc...
- Use LC41, LC42 version for automatic fill/empty operations
Starting at
$275.00
(LC40-1001)
DataPoint™ LC52 Remote Level Controller
The LC52 general purpose controller provides single tank level indication with 2 relays, up to three setpoints and an isolated analog repeater.
- 3.5 digit LED display indicates level in custom engineering units
- Fail-safe relay control of pumps or valves with 0-60 second delay
- Easy set up with pushbutton calibration for span, display and relay setpoints
- 35mm DIN rail or panel mount polypropylene (PP) enclosure with removable terminal strips
- Invert switch changes relay state from NO to NC without rewiring
- Simple controller for operating 2 alarms or 1 auto fill/empty with alarm
- Bar graph provides instant confirmation of transmitter's operational performance
- Lock-out feature prevents inadvertent setting changes
Starting at
$485.00
(LC52-1001)
CLC Series Liquid Level Controllers
ProSense CLC series liquid level controllers detect and control levels of conductive liquids (tap water, seawater, sewage, chemical solutions, coffee, ice cream, etc.) in dual-probe pump-up or pump-down applications. The dual probe system uses the conductive properties of the liquid to complete a circuit between a probe and common as the liquid makes contact with both probes. The output relay is used to control pumps, solenoids or valves to automatically lower, raise or maintain the level of liquid in the tank.
- Controls level of conductive liquids in pump up (Fill) or pump down (Drain) applications
- Probes are pulsed with a DC voltage to prevent electroplating
- Adjustable sensitivity range to meet a large variety of liquid types
- LED status indication
- Uses industry-standard 8-pin connector
