The PDCR1800 transducer (mV output) and the PTX 1800 transmitter (4 to 20 mA output) are the latest generation of fully submersible titanium high-performance sensors for the measurement of hydrostatic liquid levels. 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.
