Introduction

Measurement principle

The Rosemount 3100 Series is a liquid level transmitter based on ultrasonic technology that is suitable for many liquid applications. 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 as a 4–20 mA signal (and a digital HART® signal on the Rosemount 3102 and 3105).

The Rosemount 3102 is used for measuring the level only. The Rosemount 3102 and 3105 can calculate distance-to-surface, contents (volume), or open channel flow, and then output the result as a 4–20 mA signal and a digital HART signal.

An integral temperature sensor continuously measures the air temperature around the transmitter. It then computes the speed of sound in air, automatically compensating the calculated distance for temperature effects. The Rosemount 3102 and 3105 have a remote temperature sensor option.

Special features

Advanced software features on the HART transmitters (Rosemount 3102 and 3105 only)

■

Learn routine (false echo registration) — The transmitter can learn to ignore up to four false echoes, caused by the pulse signal reflecting off obstructions.

■

Empty tank mapping — When a tank is empty, the transmitter can learn to ignore up to four false echoes, without the need for user interaction.

■

Present depth — The bottom reference can be automatically set using a known user-entered depth.

■

Set as empty — When the tank is empty, the bottom reference can be automatically reset to the measured distance.

■

Distance offset — The distance to the surface can be adjusted by a user-entered positive or negative offset value.

■

Level offset — The level can be adjusted by a user-entered positive or negative offset value.

■

Bottom blanking — The transmitter can be set to ignore an area of the tank bottom to avoid false echoes from obstructions.
