HydrINS is an easily deployed and cost-effective flow meter providing highly accurate bi-directional measurement for water distribution and raw water pipelines. Robust, watertight and compact,  it features a highly accurate electromagnetic sensor and an integral transmitter enabling multiple telemetry options or simple totaliser. The highly versatile unit is widely used throughout the world and available in various lengths to suit pipe diameters from 100mm to over 2000mm. It is equally well deployed for permanent or portable applications, inserted through standard under pressure tapping, with no interruption to supply. BSP and NST threads are available.

HydrINS can be used throughout the water distribution network, metering at reservoirs, treatment works, pumping stations, irrigation, water pipes, zoning and DMA implementation, night flow monitoring and meter testing.

Winfluid software (PC or PDA) provides easy programming, download and data analysis. The unit uses stainless steel electrodes to enhance measurement accuracy and avoid drift, and features a re-enforced stem with anti-ejection chain, locking nut and insertion point clamp to ensure correct and safe installation on a pressurised water network.

HydrINS 2 features a plastic head which is IP68 and UV protected. It can be supplied with a large LCD display unit for instant readouts or connected to a Radcom LoLog Vista for both immediate data display and logging functionality.

The unit is powered by long-life lithium batteries or via external DC power and has alarm and pulse outputs with 2 4-20mA optional outputs.
