upcoming maintenance work using trend analysis. Diagnostic functions can also be triggered manually at any time via the cloud. The diagnostic messages are standardised according to NAMUR NE 107.
THINKING OUT OF THE BOX: OFF- LABEL APPLICATIONS
Endress+Hauser clamp-on sensors for non- invasive flow measurements without pipe work or process stops.
otherwise a straight section around seven times longer would be required, which is often not available in cramped systems. Twice the nominal diameter is also sufficient for the outlet section; FlowDC flowmeters can therefore even be installed where there is not enough straight pipe section available for other devices.
WEB SERVER IN THE DEVICE – DIRECT ACCESS TO ALL FUNCTIONS User support through software is a key feature of both Prosonic Flow devices. All diagnostic, configuration and device data can be accessed directly and with clear user guidance via the built-in web server. Even during installation, the signal quality can be checked either via the control panel of the transmitter or through the web browser of a mobile device. This makes it very easy to determine the optimum position of the sensors. The web server in the device eliminates the need for external tools and data, speeding up everything from configuration to device maintenance.
HEARTBEAT TECHNOLOGY INTEGRATES TEST FUNCTIONS As with the entire Proline product range, Prosonic Flow devices are equipped with Heartbeat Technology. Devices with Heartbeat Technology have self-diagnostics, self-monitoring and verification functions, can regularly report their status to the cloud and, for example, make it possible to plan
The transmission of ultrasound to the medium in the pipe is dependent on perfect acoustic coupling. However, gels and pastes that ensure a gap-free connection between the sensor and the pipe have a major disadvantage: they age and can wash off or dry out depending on the ambient conditions, changing their acoustic properties in the process. The result is a permanent drift that is difficult to predict because it is strongly influenced by variable factors such as the ambient conditions.

SIMPLICITY MEANS COST-EFFICIENCY On the engineering side, technical performance is without question a key argument for or against a particular instrument. The selection criteria can be clearly defined and applied. The effort involved in mounting and installation, parameterisation and commissioning, maintenance and servicing over the service life is not specified in any data sheet with hard values. The bottom line is that these are costs that are often not recorded at device level.
User-friendly operation – web server offers full remote access, while the device’s display offers convenient on-site interaction.

Instead, Endress+Hauser uses long-term stable pads or heat-resistant metal foils, which make the regular replacement of paste or gel superfluous. If drift due to aging is excluded, systematically deviating measured values compared to other measuring points can therefore be attributed to other causes, such as the formation of deposits in the pipe. Changing gas or particle contents in the medium can have a similar effect on the measured values. “We can also indirectly determine more than just the flow rate,” says Thomas Jahn. “How such off-label applications can be used innovatively is something we have to specify together with the customer for specific cases. However, we are already considering experimental use in real applications,” adds Jahn.
OPEX, i.e. operational expenditure, or life cycle costs, aka TCO, are not the primary responsibility of engineering and technology departments. However, high operating and maintenance costs are noticeable at this level, albeit in a different currency: working time. The clamp-on flowmeters from Endress+Hauser address this problem at all levels with the greatest possible simplicity. Simple installation during the ongoing process, easy configuration and parameterisation, easy access to the devices via web browser from anywhere in the world, permanent maintenance-free, acoustic coupling – all this adds up to a clear plus on the bottom line. The already high technical performance in the core areas of application and the first exciting off-label applications such as the detection of deposits in pipes or gases or particles in the volume flow mean that we can expect a lot more from the Prosonic Flow clamp-on device family with continuous further development.
