Sonde PURGE

SIG monitor water quality at the «dead ends» of the network by measuring turbidity every 15 minutes. If the 0.5 NTU threshold is met, the operation is complete. Otherwise, an extended flush lasting approximately 2 hours is performed until the level returns to the required standard.

The goal is to provide technicians with a compact analysis system that is easy to install and connect. The data must be accessible remotely, with an alert sent via a wireless network when the threshold is reached, in order to optimize travel.

The project involved developing the mechanical and electronic components of the probe, called the «Purge», designed to be integrated into the test bench used for flushing the network. This probe, which communicates via the LoRa network, enables the measurement of turbidity, temperature, conductivity and, optionally, velocity or flow rate. It aims to simplify field operations while improving real-time monitoring.
