Ultrasonic Flow Meters

Digital Correlation Transit-Time Ultrasonic Flow Meter provides the ideal combination of economy, accuracy (+/- 0.5% of reading) and installation (no sensing ports to plug). Designed to give the end-user high performance at an affordable price, the Innova-Sonic® Model 206 features advanced PicoFly™ measurement technology. PicoFly™ represents an order-of-magnitude improvement in transit-time measurement technology, allowing far superior response to changes in flow (with much greater resolution) and outstanding low flow detection. This is because PicoFly™ allows transit time-of-flight to be measured in picoseconds 10 -12 (one trillionth of a second) rather than the typical nanoseconds 10 -9 (one billionth of a second). For these reasons, the Innova-Sonic® In-Line is becoming increasingly popular for maritime use, and is one of only a few flow meters assessed by the American Bureau of Shipping for shipboard use. Indeed, for most of the same reasons described above, Sierra's Innova-Sonic® Model 205 Clamp-on Transit-Time Ultrasonic Flow Meter is being used by the United States Navy for both fuel oil and water measurement. It shares all of the same great features as the in-line meter, but with the added benefit of "clamp-on" sensors that can be affixed to the outside of fuel and water lines with no intrusion into the piping at all. This makes retrofitting existing systems very easy.
