Solinst Barologger Edge Atmosfærisk-lufttrykkmåler

Solinst Barologger Edge brukes til å automatisk kompensere måledata fra Leveloggeren for endringer i atmosfærisk lufttrykk. Dette gir en svært nøyaktig måte å beregne endringer i vannstand på.

  • En Barologger kan kompensere alle Leveloggere utplassert innenfor 30 km radius
  • En Levelogger produserer kompenserte datafiler automatisk basert på målinger fra barometeret
  • Bruker algoritmer basert på lufttrykk i stedet for vanntrykk for å gi maksimal nøyaktighet

Description

The Levelogger Edge measures absolute pressure (water pressure + atmospheric pressure) expressed in feet, meters, centimeters, psi, kPa, or bar. The most accurate method of obtaining changes in water level is to compensate for atmospheric pressure fluctuations using a Barologger Edge, avoiding time lag in the compensation.

The Barologger is set above high water level in one location on site. One Barologger can be used to compensate all Leveloggers in a 30 km radius and/or with every 300 m change in elevation.

The Levelogger Software Data Compensation Wizard automatically produces compensated data files using the synchronized data files from the Barologger and Leveloggers on site. The Barologger Edge records atmospheric pressure in psi, kPa, or mbar. When compensating submerged Levelogger Edge, Gold or Junior data, Levelogger Software Version 4 can recognize the type of Levelogger and compensate using the same units found in the submerged data file.

The Barologger Edge uses pressure algorithms based on air rather than water pressure, giving superior accuracy. The recorded barometric information can also be very useful to help determine barometric lag and/or barometric efficiency of the monitored aquifer.
