Hydreka - Model PTX/PDCR -Piezometric Probe

The Winfluid interface allows the sensor to be programmed for alarm management based on min/max values or on acceptable flow rate range, to correct the measured value, to define level/flow rate conversions (free surface values) and to create measured data reports.

Fully submersible pressure sensor for:

• Potable water network monitoring
• Sewer network monitoring
• Water bodies monitoring
• Aquifer monitoring

It can be used for height/flow calculations :

• Calibrated dams (weirs…)
• Venturi channels

• Rugged structure
• Waterproof structure (due to high pressure polyurethane injection)
• High performance accuracy, stable over extended lifetime
• Kevlar® strain relieved vented cable, supporting more than 50 kg (22.7 lb)
• Vented polyurethane (Model 1830 – adapted for potable water) Hytrel® 6108 (Model 1840 – hydrocarbon compatible) cable
• Titane body for compatibility with aggressive medias
• Cable clamp system for waterproofing
• Interfaced with HYDREKA data loggers

• Accuracy: Combined effects of Non-linearity, Hysteresis and Repeatability: +/-0.1% FS or+/-0.06% FS
