Emerson introduces new Rosemount^® ultrasonic level transmitters

Non-contacting transmitters provide a fit-and-forget solution for a wide range of continuous level monitoring applications

AUSTIN, TEXAS (July 16, 2007) – Emerson Process Management has expanded its extensive range of level measurement instrumentation with the introduction of the Rosemount 3100 Series Ultrasonic level transmitters. The new range offers Rosemount reliability and predictive intelligence in an easy to install and configure package. The 3100 Series 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.

The transmitters can be combined with the Rosemount 3490 Series of wall and panel mounted control units, providing power and comprehensive control options. The transmitter is available with two integral relays, adding to the local control functionality and can also provide both high and low level alarms.

The three new transmitters include the 3101, designed for use where an economical liquid level measurement is required with a 4-20 mA output; the 3102 which includes HART communications and integral relays; and the 3105 which is certified intrinsically safe and can be used to measure distance, level, or calculate volume or flow in an open channel.

These new Rosemount ultrasonic transmitters add to the Emerson portfolio of level instrumentation that includes transmitters based on five different measurement technologies - differential pressure, non-contacting radar, guided wave radar, ultrasonics, and vibrating fork.

Rosemount 3100 Series Ultrasonic transmitters are part of Emerson's broad range of intelligent, digital field devices that power the PlantWeb^® digital plant architecture to improve plant efficiency by 2% and more through delivering asset optimisation, process automation, and management execution.
