1.1 Level

The Levelogger Gold uses a high quality piezoresistive silicon pressure transducer packaged in 316L stainless steel housing. It gives high accuracy and high stability. The Levelogger body is coated with Zirconium Nitride (ZrN) to give corrosion resistance. All Leveloggers measure total or absolute pressure. When the Levelogger is operating in open air, it is recording barometric pressure and converting that pressure reading to its water level equivalent above the logger’s pressure zero point of 950cm (31.17ft). When submerged, it is recording the combination of barometric pressure and water pressure. The Levelogger converts the total pressure reading to its corresponding water level equivalent. Actual water level is obtained by compensating for barometric pressure. The best method to compensate for barometric pressure is to employ a Barologger above the water level, somewhere on site, to obtain records of barometric pressure. The Levelogger Software includes a Barometric Compensation Wizard, which guides the user through the automated process of barometric compensation. Manual methods can be employed to determine the absolute water level using barometric records collected on-site or available from a local weather station (i.e. Airport). Water level readings from the Levelogger Gold, LT and LTC models are temperature-compensated.
