The DCX-22 Self Contained Water Level Dataloggers are highly accurate, self-contained, battery powered absolute pressure water level loggers designed to record water depth and temperature over long periods. The absolute pressure water level sensor, electronics and battery are housed in a rugged, double-sealed 316 stainless steel tube for long term submersible deployment. The DCX-22 Self Contained Water Level Dataloggers require no external wires and may be suspended with any suitable and secure cable. When it's time to download the recorded data, the DCX-22 is simply retrieved from the measurement point and the double sealed end cap is then removed to access the absolute pressure water level sensor's data port.
When using the DCX-22 Self Contained Water Level Dataloggers in shallow water depths where the influence of barometric pressure changes should be considered, the DCX-22 Barologger is placed at the surface near the Self Contained Water Level Datalogger, to record the barometric pressure. The two values are then quickly and accurately correlated by the software once the data files are downloaded to your PC. The DCX-22 Barologger is built to the same exacting specifications as the DCX-22 Self Contained Water Level Dataloggers except that its sensor and electronics are calibrated to read and record barometric pressure.
Warning: Non-vented water level loggers may have readings with errors of up to 10 inches due to barometric pressure changes. Global Water's WL16 Water Level Loggers use vented cable to prevent this issue from affecting your valuable data.
