Singapore navy picks Sierra ultrasonic flow meter

A Sierra Instruments product story
Edited by the Engineeringtalk editorial team Sep 15, 2008

When a ship of the Republic of Singapore Navy (RSN) deployed overseas recently, it did so with a Sierra Innova-Sonic Model 206 In-Line Ultrasonic Flow Meter installed in its refueling system.

Before choosing the Sierra Model 206 In-Line Ultrasonic, an exhaustive search was undertaken to identify the best meter to check the fuel amounts received.

The RSN chose Sierra's Innova-Sonic In-Line Digital Correlation Transit-Time Ultrasonic flow meter because it provided the ideal combination of economy, accuracy (+/- 0.5 per cent of reading) and installation (no sensing ports to plug).

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).

Sierra's Innova-Sonic Model 205 Clamp-on Transit-Time Ultrasonic Flow Meter is also being used by the United States Navy for both fuel oil and water measurement.

It shares all of the same 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.
