Product Details

Rosemount 3102 Ultrasonic Liquid Level Transmitter

The Rosemount 3102 uses ultrasonic technology to continuously measure liquid levels in a variety of industrial and water applications including storage tanks, effluent pits, reservoirs, and filter bed levels.

Measures liquid level from 0.3 to 11 metres
Volume or open channel flow can be calculated.
Glass-filled nylon housing with PVDF wet-side
2” BSPT thread for mounting
2 M20 conduit entries with nylon cable glands
2-wire 24V direct current loop-powered (external power supply is required)
4-20mA and digital HART outputs
2 off integral signal relays
Integral push-buttons for menu system navigation and application set-up
Integral LCD display of metric/imperial measurements and for menu system
Low cost of installation/commissioning and minimal maintenance cost


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

Rosemount Ultrasonic Level Transmitter

The Rosemount ultrasonic liquid level transmitter has a 36ft (11m) 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 transmitter then calculates the liquid depth (level) and outputs the level ranging between 4mA and 20mA signal with HART communication.

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