Measuring flow rate correctly at any location
Smart technology for measuring at historical sites
Telsa is tasked with measuring the flow rate at a point where water from a 'suone' enters. 'Suonen' are historical channels in the Valais mountains that are difficult to monitor due to their construction and location. With the help of Endress+Hauser, Telsa was able to install a measuring solution after a collection point that records the values very accurately and outputs them via mobile.

"The installed flowmeter is used to measure the water volume for billing purposes, but also to alert in the event of a breach in the irrigation channel dike or in the case of severe flooding."

Challenge
The typical 'suonen' in the Swiss Valais are water conduits that date back to the Middle Ages and are still being used today. This was previously routed on wooden constructions along the steep rock. Today, the water flows into collection points and is conveyed from there in open concrete pipes. The open construction makes the required flow measurement by the end customer difficult. Thanks to Endress+Hauser, Telsa was able to install a reliable monitoring solution that is remotely accessible.
Solution
Endress+Hauser created an algorithm to determine the flow rate based on the level to match the geometry of the open concrete pipes. The data are transmitted to the Netilion IIoT ecosystem via wireless communication. This cloud-based solution allows the end customer to record the water volume continuously, determine annual volume and in the future to compare the annual values.
Implementation
The algorithm was stored in a "level/flow rate" table of values in the Prosonic S transmitter. The table contains 32 value pairs so the current level can be assigned a flow measured value (volume flow l/s). Furthermore, the total flow is also recorded (m3). The measured values are saved locally every 5 minutes and sent every hour via FieldEdge SGC200 to the Netilion IIoT ecosystem for storing. The measured values can be viewed and evaluated using the Netilion Value basic web application.
Scope of delivery
Endress+Hauser's solution:
Prosonic FDU90: ultrasonic sensor for level and flow measurement for connection to transmitter
Prosonic FMU90: transmitter in field housing or DIN rail housing for up to 2 ultrasonic sensors
Edge Device: FieldEdge SGC200 transfers the measured values to the Netilion ecosystem
FieldPort SWA50: intelligent Bluetooth® adapter for all HART field devices
