Top mounted non-contacting ultrasonic level measurement in open and closed tanks, wet wells and open channel flow measurement. This technology is unaffected by fluid properties (density, viscosity, and liquid surface) and offers intrinsically safe versions for hazardous area use.‚Äč

 

Rosemount 3100 Series Level and Flow Transmitters (3107 3108)

The Rosemount 3100 Series Ultrasonic Level Transmitter is the reliable and cost-effective, non-contacting measurement solution from Emerson. Time proven ultrasonic technology with advanced software and state-of-the-art electronics delivers high reliability in a wide variety of applications.

The rugged all UPVC construction is ideal for exposed site applications such as reservoirs, rivers, remote works, and waste water and effluent treatment plants. Transmitters are factory sealed (IP68) for use in wet-wells and sumps up to 39 ft. (12 m) deep.

The 3107 is for level and volume measurements in wet-wells, sumps, and tanks. Choose the 3108 for open channel flow measurement.

  • Continuous non-contacting measurement with no moving parts
  • UPVC housing and wetted material
  • Volume and open channel flow calculations with pre-programmed library
  • Fast and simple to install and configure
  • Easy plant integration with 4-20mA / HART® output and PlantWeb support
  • 2-wire dc loop-powered
  • MCERTS-certified 3108 when used with a Rosemount 3490 Series Control Unit
  • Intrinsically Safe (IS) approvals

3490 4-20 mA and HART® Compatible Control Units

The Rosemount 3490 Series of wall and panel mounted control units provide comprehensive control functionality for any 4-20 mA or HART® compatible transmitter. A back-lit display gives clear visual indication of the measured value and status of all inputs and outputs. The 3490 provides an intrinsically safe 24V dc power supply to the transmitter. Five relays are provided and are fully field programmable to perform a wide variety of control, fault indication or alarm duties.

  • Tough weatherproof wall mount enclosure for internal or external mounting
  • Accepts any 4-20 mA or HART compatible input
  • Five field adjustable control relays
  • Bright local display of measured value
  • Pre-programmed with tank shapes, flow algorithms and pump control routines to simplify configuration
