What Are The Special Considerations When Measuring Ammonia? |
|
Answer» Tanks with anhydrous AMMONIA have a heavy vapor above the surface that attenuates the signal from the RADAR transmitter. A higher pressure in the tank will cause a more attenuated signal. A special formula is therefore used to evaluate what the maximum measuring RANGE is in anhydrous ammonia as a function of the pressure in the tank. For the 5600 the formula is: Max Measuring Range (m) = 20 / Pressure in Bar Note that, when measuring anhydrous (aqueous) ammonia, this formula does not apply. Hydrous ammonia has a HIGH dielectric constant and therefore provides good reflection.
