Non-contacting transmitters for continuous level monitoring applications

July 23, 2007

The Rosemount 3100 Series ultrasonic level transmitters offer reliability and predictive intelligence in an easy to install and configure package. The transmitters are ideally suited for monitoring liquid level in tanks and open air applications where long maintenance intervals are a key requisite. The non-contact sensor in the 3100 is made from an inert material offering superior corrosion resistance and low maintenance requirements. The integral or remote mounted temperature sensor enables automatic corrections where temperature changes in the tank free space could otherwise result in an inaccurate reading. Available with threaded or flanged connections and suitable for the chemical, oil and gas, power, water and wastewater industries, the transmitters are easy to install and also, thanks to several pre-programmed laws and strapping tables, easy to configure. Diagnostic information from the 3100 can be captured by using Emerson’s AMS™ Suite software, or by using any other HART® communications tool such as the 375 Field Communicator. These tools, or the local operator interface, can also be used to configure the transmitter.
