Elster® Q.Sonic® Plus

The patented path configuration - a fully symmetrical layout of four swirl paths with double reflection and two single reflection paths - enables the measurement of both swirl and asymmetry, resulting in previously unequalled profile recognition and diagnostic possibilities.

Another innovation of the Q.Sonicplus is that it can be equipped with an internal pressure and temperature measurement function.

This means that the device measures both the gas pressure and temperature of the measuring tube.

On the one hand, these measurements allow for a more accurate calculation of the Reynolds number for the flow profile analysis and on the other, they can be used to correct the meter body diameter and path geometry.

This is useful if the process conditions differ massively from the conditions during the calibration process since both high pressure and high temperatures result in an increase in the tube cross-section and a change in path lengths and angles.

Encrypted data is managed by the real time operating system - RTOS philosophy pioneered by Green Hills Software.

Integrity RTOS provides one of the most reliable operating platforms in the world delivering piece of mind with the highest security level that is currently achievable for a real time operating system.

The electronics are located in a flame-proof housing with a separate connection compartment for field wiring.

Thanks to its modular hardware design with a free slot, the device is also prepared to tackle future requirements.

For user operation the system is equipped with a graphical user interface with touch screen functionality.

SonicExplorer, a PC based software package, for the operator, service, technician and engineering world is used to configure, diagnose, and monitor the Q.Sonicplus flow meter either local or remote.
