Vortex and Fluidic Flowmeters (Part 2 of 4)

Coanda effect fluidic flowmeters contain passages or other hydraulic mechanisms that allow a portion of the downstream fluid to be fed back near the inlet of its fluidic oscillator. By impacting the incoming fluid, the feedback flow causes the main flow to preferentially attach itself to the opposite surface of the flowmeter. This increases the opposite feedback flow and forces the main flow away from that surface. click for more...

Part II: Measuring Gravity-Fed Flow:
Key Considerations Gleaned from a Real-Life Application

The specific example I cited last month was a tank operated as a binary separator that was fed in the middle where the feed flow contained heavy liquid that drained out the bottom while the light liquid overflowed at the top. Sizing and installation issues involved with the feed and bottom flowmeters were discussed. Now let’s take a look at the overflow flowmeter. click for more...

Troubleshooting Low-Flow Conditions: How to Diagnose a Slow-Filling Tank

Sometimes simple rules of thumb are good enough to solve the problem at hand. Suppose that an installed system consists of a water tank, a pump, and discharge piping to an atmospheric vessel located 60 feet above the pump. The pump is operating and all valves in the piping are completely open. The flowmeter installed between the pump and tank indicates a low flow and the tank fills slowly. What potential problems could exist and how would you address them? click for more...
