Water Gulping Detection
11 Nov 21
A method to detect gulping in a pump driven by a motor drive to pump a liquid includes: determining a value of a work indicator corresponding to work performed by a pump pumping a liquid; comparing the value to a first threshold; changing a value of a tracking variable by a first amount if the value of the work indicator is below the threshold; changing the value of the tracking variable by a second amount if the value of the work indicator is above the threshold, wherein the first amount and the second amount have opposite signs; and determining that a gulping event occurred if an absolute value of the tracking variable is larger than an absolute value of a second threshold.
