Level Sensors & Controllers

Flowline® Ultrasonic Level Sensors and Switches


The Flowline EchoPod®, EchoSonic® II, Echotouch™, EchoSpan® and EchoSwitch® are innovative ultrasonic liquid level sensor families that replace float, conductance and pressure sensors that fail due to contact with dirty, sticky and scaling liquids in small, medium and large capacity tanks. These liquid level sensors can be used in either open or enclosed tanks (not suitable for pressurized tanks). PC software configured or pushbutton configured models are available. - software or pushbutton configured!


ProSense® Float Level Switches


ProSense float level switches provide a low-cost general purpose solution for single point monitoring of liquid level in a variety of applications. Designed for shock and vibration resistance, ProSense float level switches ensure long and trouble-free service. Powerful permanent magnets within the float actuate a highly reliable and repeatable hermetically sealed reed switch as the float rises and lowers with liquid level.- general purpose, low-cost!

Ultrasonic Level Sensors & Switches (Software Configured)Ultrasonic Level Sensors & Switches (Software Configured)


The Flowline EchoPod and EchoSonic II are innovative ultrasonic liquid level sensor families that replace float level sensors, or conductance and pressure sensors that fail due to contact with dirty, sticky and scaling liquids in small, medium and large capacity tanks. These liquid level control sensors can be used in either open or enclosed tanks, but they are NOT suitable for pressurized enclosed tanks.
Ultrasonic Level Sensors & Switches (Pushbutton Configured)Ultrasonic Level Sensors & Switches (Pushbutton Configured)

Pushbutton Configuration: With no software or PC required, the Echotouch, EchoSpan, and EchoSwitch ultrasonic level sensors are easily configured using integral pushbuttons and LCD digital display. Configuration parameters are organized in a simple menu structure so that parameter values are easily accessed and set or changed as needed.
Flowline Level Sensors (Contact)Flowline Level Sensors (Contact)

Ultrasonic Level Switches:
are intrinsically safe and provide reliable liquid level detection of chemical, solvent, hydrocarbon and petroleum based liquids.
Vibration Point Level Switch:
provides reliable liquid level detection of dirty liquids such as those with light to medium coating, scaling or foaming characteristics.
Capacitance Level Switch:
provides reliable high or low liquid level detection of water based conductive liquids with light coating, crystalizing or scaling characteristics with a 1A relay output.
Buoyancy Level Switch:
provides reliable liquid level detection of relatively clean water and chemical solutions.
Flowline Level ControllersFlowline Level Controllers

Switch-Pro™ general purpose level controllers are available in three discrete sensor input configurations for alarms, pump and valve control. The LC52 DataPoint™ general purpose controller for analog sensor inputs provides single tank level indication with 2 relays, up to three setpoints and an isolated analog repeater.
Float Level SwitchesFloat Level Switches

These switches are available in several different material constructions for compatibility with many types of liquids, a wide temperature range, and various system pressure requirements. Vertical and horizontal mounting styles with several mounting thread variations are available for ease of installation.
Submersible Level SensorsSubmersible Level Sensors

The ProSense SLT series submersible level sensors provide continuous liquid level measurement by sensing the hydrostatic pressure produced by the height of liquid above the sensor and providing a 4-20 mA output signal compatible with PLCs, panel meters, data loggers, and other electronic equipment.
