Principles of operation SITRANS LR260 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of liquids and slurries. (The microwave output level is significantly less than that emitted from cellular phones.) Radar level measurement uses the time of flight principle to determine distance to a material surface.

TVT, amongst other characteristics. The true echo is selected based on the setting for the Echo selection algorithm (Algorithm 2.2.4.1.1 (Page 82)). SITRANS LR260 with mA/HART Operating Instructions, 11/2019, A5E32337683-AD...
Page 153: Echo Lock
If the echo selected by Algorithm is within the Echo Lock window, the window is centered about the echo, which is used to derive the measurement. ● Lock Off: SITRANS LR260 responds immediately to a new selected echo (within the restrictions set by the Maximum Fill / Empty Rate), but measurement reliability is affected.
