Liquid Level Sensors and Controllers
Reflective Ultrasonic Level Sensors
Non-contact EchoPod and EchoTouch reflective ultrasonic liquid level sensors feature Flowline's proprietary Reflective Technology™ that delivers reliable level measurement in condensing environments. Both general purpose and intrinsically safe versions are available with single and multifunction capabilities, including continuous level measurement, switching and control.
Flowline Ultrasonic Level Sensors
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 Configured Ultrasonic Level Sensors Overview Pushbutton Configured Ultrasonic Level Sensors/Transmitters Overview

Flowline 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.
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. 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.
Vibration Fork Level Switches
ProSense VFL Series liquid level switches are offered in two process connection sizes with short and extended insertion lengths, standard and high temperature constructions, and a 3-wire DC switch output for connection to controller inputs or a 2-wire AC/DC switch for control of valves and pumps.
ProSense Submersible 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.
Proximity Level Sensors
offers a variety of capacitive level sensors. NPN and PNP logic
outputs and normally open or normally closed output models are
available. All capacitive proximity sensors have LED status
indicators to verify operation at the switch; and all capacitive
proximity sensors are IP65 or IP67 rated.
Ultrasonic: SU, UK, UT and TU series round body reflective ultrasonic distance sensors emit a sound impulse and measure the elapsed time of the returned echo signal reflected off of a detected object.
