HydroMast
Description: The hydromast is a unique flow sensor designed to measure the velocity magnitude and flow direction near surfaces. It is developed as part of H2020 projects Lakhsmi and Iliad to address the lack of in-situ measurement technologies capable of measuring near-bed flow conditions in shallow waters.
Key features:
- Robust underwater sensing in turbid flows from 0.3 to 1.2 m/s, up to 30 m depth, and waves
- Can be mounted horizontally or vertically on natural or built surfaces
- Spatially distributed, synchronous flow-sensing arrays of hydromasts can be deployed for large-scale mapping of near-bed flows
- Possible live data feeds (directly from device (RS485), through communication module via LoRa, GSM) or offline logging with battery pack
Sectors: harbour safety, flow measurement for oil and gas riser, coastal and river sediment transport, coastal insurance
