Hi all -
We have a series of tanks ( 5 to 8 feet high) wich are filled with water.
At some point Bunker # 2 oil is floating on top of the water. When the level of oil reaches 6 inches we whant an alarm and a second one when it
reaches 12 inches. The total level is varying from 25% to 100%.
We have Warrick dual density float system installed but need to change the system because the float sometimes gets stuck by dirt (leaves, sludge, etc) . We have tried capacitance and press x-mitter but the precision is not good
enough and the capacitance probe gets oily and gives false signals.
10 years ago I work with a ultrasonic level transmitter wich could give a signal for each surface it passed trough... I remember the brand to be "Rexfor or Rexnor" or something like that.
We also tried to clean the actual probe time to time but installation of water jets was prohibitive in this remote location.
Do you have any suggestions on instruments to use to solve this situation.
