Ranging of a Radar Level Transmitter

Ranging of a Non-Contact Level Transmitter.

When i was given the project of installing Level transmitter i thought it would be a cake-walk for me,instead it turned out to be a night mare.With hell of calculations boggling my mind then, i searched everywhere for help, even googled but came across nothing  that could bear fruit. This is what make me write this post so that many others could take at least some help.

Dimensional Drawing of the tank.

We begun ranging the transmitter simply from the top of the nozzle to the bottom of the tank with a span reading of 600+2100+280=2980 mm and thought it will as simple as this.The very next day we found our tank overflowing with solvent.Now that was dangerous.It should solved.After hundred of attempts we finally arrived at the final values.

Zero reading or empty calibration was entered as 600+2100=2700

Span reading was entered as  2100-280=1820 mm

The dead level needs to be subtracted from the total length to be measured i.e the Full Calibration value.

Also compare the Level Transmitter Value with the level indicator on tanks.
