Pressure Sensor
Precise pressure measurement in the drinking-water system. Reports unusual pressure drops or spikes — an early-warning sensor for burst pipes, failed supply hoses and installation faults.
The Pressure Sensor continuously measures the line pressure in your drinking-water installation. If pressure drops below the normal operating range — for example due to a burst pipe, a failed supply hose or a valve left permanently open — an alarm is raised. Unusual pressure spikes are also detected, as they may occur with faulty check valves.
Two variants are available: the PREWIE02 with direct Wi-Fi connectivity to the Aqua-Scope app and smart-home systems, or the PRELWE02 with LoRaWAN for locations without stable Wi-Fi and for operators running their own LoRa network.

Where to install the Pressure Sensor
The Pressure Sensor fits into any 1/4-inch opening (EU thread). That's the standard opening at every service/revision point in a drinking-water installation — for example on the backflow preventer or on the main shut-off valve right after the water meter.
If none of those points is available or the location is inconvenient, the easier alternative is on an angle valve under a wash basin. A small T-piece goes between the angle valve and the basin's supply hose — the required adapter is included in the delivery.
Alternative installation: Pressure Sensor on the angle valve under a wash basin, connected via the supplied T-piece.
