Setting Prosonic® apart from the pack

In 2003, a Florida municipality expressed an interest in exchanging paddle wheel meters with ultrasonic clamp-on devices.  The desire to change was due to maintenance and spare part availability associated with mechanical meters and evaluating technology for future expansion without significant interruption to daily output.  Due to the continuous process associated with water treatment and the supply chain to their customer base, the proposition of non-invasive measurement was ideal.

Although the ultimate goal was to replace paddle wheel meters due to maintenance and availability, the measuring values, reliability, and overall support would be considered the cumulative metrics Prosonic would be qualified with. After all, when properly maintained, the mechanical meter provides an acceptable measurement value, ease of understanding to operators, lower acquisition costs, and the 4-20mA/Pulse output required to report information about the water treatment process.

Of course any "clamp-on” device offers the promise of installation without interrupting the process.  So the question became, "how do we elevate Prosonic above the 4-20mA level and remove supplier neutral benefits from the equation?” The Frequency Sweep technology that enables Proline Prosonic presented an opportunity to prove our meter in various applications due to the ease of installation with a single pair of sensors.  This was an outstanding benefit of Prosonic that could easily demonstrate a reduction in spare parts, maintenance procedures, and reliance on the supplier to always ask the right questions.

The field proven performance of Prosonic combined with the speed of local production, know-how of our sales and application engineers, and the real-world expertise of our service technicians were all significant points of interest for our customer.  In the end, positioning a fantastic piece of hard-ware with outstanding human capital set Endress+Hauser apart from the rest.

With Fieldcheck, the following possibilities are available to strengthen our solution with the customer's respective success factors and concerns.

	System verification with Prosonic sensors external to the pipe system in drinking water is valuable to extend the calibration intervals associated with wetted, intrusive meters.
	Fieldcheck provides a reporting mechanism for the installed base and traceability for the output of water from the plant as reported by the flow meters with long term comparison functionality in Fieldtool Software with Read Only reports.
	System verification can be performed regardless of process conditions with a high degree of confidence and repeatability using an externally traceable tool that can be calibrated annually to a reference device at Endress+Hauser.
	With Fieldcheck, the standard transmitter verification checks are performed to analyze system linearity, accurate processing of flow signals, and component drift vs. factory standard reference tolerances that are established at the time of local manufacturing.
	With Fieldcheck Verification for Prosonic sensors, the sensor test block can prove the sensors, cables, and system functionality to repeatable, have not been damaged or experienced drift vs. known factory tolerances.  The internal clock speed can be proved within 0.1 nanoseconds at known sound speeds.
	Fieldcheck for products other than Electromagnetic flowmeters provides an externally traceable metric that is un-matched in the market today. Endress+Hauser can offer Fieldcheck for all flow technologies including Coriolis, Electromagnetic, Vortex, Thermal*, and Ultrasonic.

Today, the municipality has more than 70 Proline Prosonic and more 30 Proline Promag flowmeters installed throughout their municipal infrastructure.  Proven performance, Fieldcheck, and local Endress+Hauser service are all factors that continue to make Prosonic the #1 consideration for any new flow measurement.
