Paddlewheel Flowmeters and why they are popular
Those of us in the instrumentation industry know there is a simple rule; if you want higher accuracy, it will usually cost more money. Paddlewheel Flowmeters come very close to dispelling that rule. Due to modern technology, advanced plastics and metals, solid-state circuitry, and good old capitalism the high cost of accuracy has been challenged. With the use of computer-enabled testing facilities, paddle sensors are individually bench tested and are accurate to within 1% of the full scale range reading…
