22. Enter the P1 Sensor Position, i.e. the center position of the Liquid
Pressure sensor membrane.
23. Enter the Hybrid Min Level. This value specifies the lowest product level
at which TankMaster calculates the Observed Density. Normally, the
accuracy of pressure sensors is poor at low pressures, i.e. at product
levels close to the sensor membrane. Therefore, you can enter a limit
below which the density calculation is “frozen”. For example, if
Hybrid Min Level is equal to 0.6 meter, TankMaster WinOpi will present
the same density value for product levels below 0.6 meter.
NOTE!
Specify the actual minimum product level and not the distance between the
pressure sensor and the product surface.
