Barometric Compensation And The Importance Of Barometric Data

Barometric Compensation Leveloggers measure total pressure (water column equivalent + barometric pressure). In order to accurately determine the true changes in water level only, barometric pressure fluctuations must be removed from the data. The simplest method to accomplish this is by the use of a Barologger suspended above high water level in… Continue Reading »

Absolute Vs. Vented Pressure

  The Solinst Levelogger is based on an absolute pressure transducer. This means the Levelogger senses and presents all the pressure it is under, both water pressure (hydraulic head) and air pressure (barometric or atmospheric pressure). However, most users are interested in just the water level or hydraulic head, so Solinst offers a separate logger, the… Continue Reading »
