Advantages of the interface measurement with ultrasonic


1. Simple structure requires only about 20 % of the costs.
2. Smaller mechanical dimensions of the system, no openings.
3. Integration on available stand pipes.
Disadvantages of well-known procedures
Floats and restrictors can supply in each case a signal for a liquid. For two independent heights of two laminated liquids therefore two independent standrohre are necessary.
The elevator movement of the floats and restrictors must be led by a pressure tight execution over into an electrical signal to be converted (e.g. during transformation in rotation).
Changes in density cannot be compensated.
Existing standpipe for restrictors are often reequipped now with systems with led microwave.
All interface measurements with led microwave or Guidet Wave radar need a Epsilon difference of at least 10. A condition is, which is lower liquid leading, those upper liquid is not leading and the Epsilon is in the upper liquid well-known.
Many non conductive hydrocarbons possess a Epsilon under 10. Also halogen hydrocarbons, which are often used as dragging and parting agents, possess partially low Epsilon.
Led microwave can measure only from above and needs direct contact for the liquid and concomitantly a pressure tight execution for the container or standpipe.
