Is there a resource for flow monitoring professionals that includes up-to-date industry, educational and product information?
Yes, the free monthly e-newsletter Focus On Flow. This newsletter helps flow professionals keep the edge on solutions, analysis and innovations critical to their success.

A: The answer depends on the Doppler sensor’s ultrasonic frequency. The higher the frequency, the better the performance in cleaner water applications. A 1 MHz Doppler sensor would be able to reliably measure velocity in flows that are as clean as 50 mg/L (ppm) of total suspended solids (TSS). [ Return to Top ] 12. Q: Why isn’t there a standard to present accuracy (both level and velocity) of flowmeters? e.g. % full scale vs. % reading A: The accuracy of flowmeters (and other instruments) is usually stated as either a % of full scale or a % of reading. It is important to understand the meaning of each as they represent very different numbers.
