1. General Introduction
Rosemount 3100 series ultrasonic level transmitter supply reliable and cost effective level, volume, and open channel flow measurements of liquids. 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.
