Application Conditions:
Slurry Splash, froth, foam, condensation, tanks with conical shaped bottom sections.
Level Technology Choice:
We have seen pressure transmitters, Radar Transmitters, and Acoustic Transmitters. The density of the slurry varies with the changes in Ore type, so pressure transmitters will always have an error. The build-up of scale over the diaphragm is also a problem. Condensation build-up will affect Radar transmitters because the Mill slurry temperature is above ambient temperature, and the signal will be attenuated by high dielectric froth and foam. The best choice will be a low, 10 kHz, or 15 kHz Acoustic Transmitter that will penetrate through highly conductive Froth and Foam and atomize the condensation from the diaphragm with each pulse. Even in small-range applications, it is the environment that we must specify the instrument on, not the range.
The 15 kHz and the 10 kHz transmitters can be operated on two wire comms, Foundation FieldBus and ProfiBus PA.
