Ultrasonic Level Transmitters Offer 12-Meter Measurement Range

Emerson Process Management has extended its range of Rosemount 3100 series ultrasonic non-contacting level transmitters with two new models designed to operate with the Rosemount 3490 series of universal controllers. The new Rosemount 3107 and 3108 transmitters work with the 3490 controllers to provide combined measurement and control of level, volume (tank contents) or open channel flow using flumes or weirs, in industrial and water utilities applications.

Both transmitters have a 12-meter measurement range and are 24V loop-powered devices with 4-20mA and HART communications. They are supplied factory-sealed in an IP68-rated UPVC housing with integral cable and stainless-steel mounting bracket. They can be used as stand-alone devices or as part of a sitewide measurement, control and data acquisition system.

Differential measurements can be made using two Rosemount ultrasonic transmitters and a single control unit. The system is programmed to display the difference or sum of the two levels or flows, as well as the individual measurements.

The Rosemount 3108 features a remote temperature probe, making it suited for open channel flow measurement when greater accuracy and precision are required. Designed to overcome the problem of inaccuracies caused by "solar gain" when the sun shines directly on transmitters installed in the open air, the compact unit has a remote temperature sensor with a two-meter cable.
