3107 & 3108 Series Level and Flow Transmitters

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

The 3107 and the 3108 are based on ultrasonic technology.

Ultrasonic pulse signals are transmitted and reflected from the liquid surface. The transmitter ‘listens’ for reflected signals (echoes) and measures the time-delay between transmitting and receiving.

The distance to the liquid surface is automatically calculated using the computed time-delay.

The 3107 has an integrated sensor for automatically compensating the Distance for temperature effects.

The 3108 has a factory fitted remote temperature sensor to continuously measure the air temperature around the transmitter. It then computes the speed of sound in air, automatically compensating Distance for temperature effects.

The level measurement (Bottom Reference minus Distance) is sent through the 4–20 mA and HART output.
