Product Details

Rosemount Ultrasonic Level Transmitter

The Rosemount ultrasonic liquid level transmitter has a 26ft (8m) range. The 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 Rosemount 3101 is used for measuring the level only.

The 3101/3102/3105 Ultrasonic Level transmitters should not be mounted directly to metal.
It is highly recommended to use Rosemount mounting flanges.
