Abstract:
1. A method of detecting the quality of a fluid in a vessel, comprising the steps of: transmitting an interrogation pulse into a vessel containing a fluid; receiving a first reflection of the interrogation pulse off of a first transition boundary; receiving a second reflection of the interrogation pulse off of a second transition boundary; measuring the time between receiving the first reflection and receiving the second reflection; determining a distance between the first transition boundary and the second transition boundary; calculating a derived characteristic of the fluid located between the first transition boundary and the second transition boundary based upon the distance between the first transition boundary and the second transition boundary and the time difference between receiving the first reflection and receiving the second reflection; determining a first configurable offset value to calculate a quality floor threshold; determining a second configurable offset value to calculate a quality ceiling threshold; and determining whether the derived characteristic is between the quality floor threshold and the quality ceiling threshold.
