FISHER buoy interface calibration
Thread Content
If the medium measured earlier was an interface, and now water is used as the reference, should one change the option in the level/interface/density menu within the instrument’s basic settings? In my opinion, if calibration is to be done using water, it should be set to level first, followed by a two-point calibration. I’m not sure if this setting is correct; I’d appreciate some guidance.
For boundary measurement using the hydrographic method, it is necessary to establish boundary markers.
On-site, whether it is the measurement interface or the liquid level, water is generally used for calibration. To measure the interface zero point when it is filled with a light medium, convert it using water as a reference
Use water for calibration – no settings are needed, as the density conversion is taken care of during the calculation
No changes to the settings are needed; during calibration with water, close the valve once, ensure that the float is exposed to the atmosphere – the zero point is reached when the float is filled with light medium. The water level can then be calculated, and the full scale can be determined using heavy medium. Two-point calibration is sufficient.
