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.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
