Saab TankRadar® Pro Tank Distances 6 Tank Distances Definitions The Distance Offset (G) is defined as the distance between the upper reference point and the flange (the flange is referred to as the Tank Radar Pro Reference Point). You can use G to specify your own reference point at the top of the tank. Set G=0 if you want the flange as upper reference point. G is defined as positive if you use an upper reference point above the TR Pro Reference Point.
Saab TankRadar® Pro Tank Distances The Tank Height (R) is defined as the distance between the upper reference point (specified by the Distance Offset G) and the lower reference point (zero level). If no datum plate or zero level exist the tank bottom usually is used as zero reference point. In this case C=0. The Minimum Level Offset (C) is always positive and is defined as the distance between the zero level (Tank Level Reference Point) and the minimum accepted level.
Saab TankRadar® Pro Tank Distances Examples The following examples illustrate how you can set the various tank distance parameters to suit your own preferred reference point settings. Example 1 If you want set Upper reference point at the tank roof G=distance between flange and tank roof (G<0). Lower reference point at the bottom of the tank.
