Innova-Sonic® In-Line Ultrasonic Flowmeter with Order-of-Magnitude Improvements in Transit-Time Measurement Technology


Sierra’s Innova-Sonic® In-Line is a state-of-the-art Digital Correlation Transit-Time Ultrasonic flowmeter designed to give the end-user high performance at an affordable price. Sierra’s advanced PicoFlight™ measurement technology is an order-of-magnitude improvement in transit-time measurement technology and enables far superior response to changes in flow (much greater resolution) and outstanding low flow detection. Innova-Sonic® In-line is an order-of-magnitude improvement over other transit-time ultrasonic instruments in use today. The instrument features our patented ultra-precise PicoFlight™ measurement technology. An industry first, this advanced technology allows the ultrasonic transit time-of-flight to be measured in picoseconds 10 -12 (one trillionth of a second) for superb resolution and extreme low flow detection rather than the typical nanoseconds 10 -9 (one billionth of a second). Innova-Sonic® In-Line is an ideal choice for any liquid flow application found in general industry. In addition, the instrument is designed primarily as a great alternative choice or replacement for magnetic flowmeter applications, with several clear advantages. The 0.5% of reading accuracy is as good as a typical magnetic flowmeter, but the ability to measure down to zero flow and the ability to measure virtually any clean liquid regardless of conductivity sets Innova-Sonic® In-Line apart. With distinctive features such as high precision, high reliability, high capability and low cost, Innova-Sonic offers low power consumption, digital signal processing with advanced noise filtering capability and outstanding applicability. Our Innova-Sonic® In-line features both accuracy and repeatability of +/- 0.1 fps, a wide operating temperature range of 32F to +140F (0C to 60C) and a bi-directional flow range of 0.0 to 33 fps liquids (0-10 mps). The instrument is ideal for clean liquid applications and is tolerant of liquids with the small amount of air bubbles or suspended solids commonly found in most industrial flow applications. Sierra’s Innova-Sonic® In-Line is designed using SLSI technology (Super Large Scale Integration) allowing ten times the component population compared to the typical Integrated circuit. The unique patented in-line spool piece design features UPVC (Unplasticised PVC) for greater tensile strength and less thermal flexing than normal PVC flanges. The stainless steel jacket keeps the internal diameter of the flow body fixed during thermal expansions or contractions and contributes to the superb (0.5% of Reading) accuracy. The Innova-Sonic In-line is easy to program via Infrared (IR) hand held remote and includes an easily readable 16 character by 2 line backlit display.
