3.From the Tank Name/Hub Position list select the tank to be configured for hybrid density calculations.

4.Enter Local Gravity, Air Density and Vapor Density. These parameters are used for calculating the Observed Density. See the TankMaster WinOpi Reference Manual (Document No. 303028EN) for more information on inventory calculations.

Enter Upper and Lower Density Limits for the Observed Density. Density values outside this range will be notified by TankMaster.

5.Enter the P1 Sensor Position, i.e. the position of the center of the Liquid Pressure sensor membrane.

6.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 reduced at low pressures, i.e. at product levels close to the sensor membrane. Therefore, you can specify a limit below which the density calculation is “frozen”. For example, if Hybrid Min Level is equal to 2.0 meter, the Raptor system will present a fixed density value for product levels below 2.0 meter.

NOTE!

Specify the actual product level and not the distance between the pressure sensor and the product surface.

7.Enter the P3 Sensor Position, i.e. the position of the center of the Vapor Pressure sensor membrane measured from the tank Zero Level/Datum Plate.

8.Click the OK button to save the Hybrid Density configuration.
