Liquid level sensor line uses ultrasonic sensing technology
AutomationDirect’s Flowline EchoTouch, EchoSpan, and EchoSwitch series of ultrasonic liquid level sensors and transmitters as well as the PodView digital level indicator are constructed with PVDF transducers and NEMA 4X polycarbonate enclosures, these sensors replace float, conductance and pressure sensors that fail due to contact with dirty, sticky, and scaling media in small, medium and large capacity tanks. Ideal for chemical, water and wastewater applications, these general purpose sensors are available with single and multi-function capabilities including continuous level measurement, switching and control.
The Echotouch LU20 liquid level transmitter features continuous level detection up to 18 feet; adjustable dead band and range filters eliminate false echo returns. Calibration takes less than a minute using the LCD display, four-button interface and intuitive calibration menu.
The EchoSpan LU series ultrasonic liquid level transmitters provide continuous level measurement up to 32.8 feet with a 4-20 mA signal output; an LCD display indicates level in inches, centimeters and percentages. Fail-safe intelligence and diagnostic feedback provide simple troubleshooting, and configuration is simple via the integral pushbutton display module.
The EchoSwitch LU series ultrasonic liquid level sensors provide continuous level measurement up to 26.2 feet; three programmable relays provide level switch or level control functions and a 4-20 mA output. Relays can be configured on a single setpoint or latched on two setpoints for automatic fill or empty in simplex, duplex, triplex level control modes with selectable time delay and fail-safe logic.
The LI40 PodView digital level indicator is a general purpose indicator that displays engineering units for level or volume when combined with all EchoPod level sensors compatible with WebCal 6.0 software. Fitted with a corrosion resistant NEMA 4/IP65 enclosure, it can be field mounted for local indication as well as be used to make simple setting changes to the sensor.
