The 1800 Series incorporates many enhanced features gained from experience in supplying thousands of sensors for small- and large-scale installations worldwide. Example applications include:

Potable water – From groundwater borehole to surface water level measurements in rivers, canals, and reservoirs.

Wastewater and remediation – Monitoring of secondary and outflow sewage levels and contaminated groundwater levels in landfill sites.

Tank Level – From land-based liquid storage vessels to on-board ship ballast tank monitoring.

Sea Water – Marine environmental applications, including tide gauging, coastal flood protection, and wave profiling, amongst others.
