GPE - Model F3001 - Ultrasonic Gas Flowmeter - Brochure

Multisonic F3001 ultrasonic ?owmeter measures the ?ow velocity of the gas via the transit times of ultrasonic pulses and calculates the ?ow rate at measurement conditions therefrom. Here use is made of the fact that ultrasonic pulses move faster in the direction of ?ow than in the opposite direction.
