Ultrasonic flowmeters use sound waves to determine the velocity of a fluid flowing in a pipe. At no flow conditions, the frequencies of an ultrasonic wave transmitted into a pipe and its reflections from the fluid are the same. Under flowing conditions, the frequency of the reflected wave is different due to the Doppler effect. When the fluid moves faster, the frequency shift increases linearly. The transmitter processes signals from the transmitted wave and its reflections to determine the flow rate. Continue reading “How Ultrasonic Flowmeters Work”
How Ultrasonic Flowmeters Work
There are several different component parts that go into a dust collector for monitoring and control purposes. In this article, we are going to focus on timer boards. We will be comparing and contrasting a few of our timer boards, as well as discussing how we could help you to better protect your equipment in the most cost-effective manner. 
The summer is always a busy time for our team, as we check and double check the formatting and information of our annual instrumentation catalog. Now that autumn is here, we’re proud to announce that the new Dwyer Catalog is now available!
