Transit-Time Ultrasonic Flowmeter Offers an Alternative Choice for Mag-Meter Applications

Sierra’s Innova-Sonic In-Line Model 206 Digital Correlation Transit-Time ultrasonic flowmeter is targeted to customers as an alternative choice for typical liquid Mag-Meter applications where high performance and affordable pricing are important. The Model 206’s ability to measure down to zero flow in clean liquids, regardless of conductivity, sets Sierra’s Innova-Sonic In-Line apart.

Sierra’s PicoFly technology allows ultrasonic 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). This enables low flow detection.

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 increased applicability. The Innova-Sonic In-line features an accuracy of ±0.5% of reading and repeatability of ±0.07% of reading, an operating temperature range of -40 °F to +176 °F (-40 °C to 80 °C) and a bi-directional flow range of 0 to 23 fps liquids (0-7 mps).

Innova-Sonic In-Line is also tolerant of liquids with small amounts of air bubbles or suspended solids, which are commonly found in most industrial flow applications.

Sierra’s Innova-Sonic In-Line is designed using SLSI technology (Super Large Scale Integration) allowing 10 times the component population compared to the typical Integrated circuit. The in-line spool piece design features a carbon steel flow body available with both ANSI and DN 16 flanges. The Innova-Sonic In-line is easy to program and includes an readable 16-character by two-line backlit display.
