The present application discloses a system and method for calculating a droplet delay time in a liquid flow of a sorting device and a sorting device, the system including a first laser source configured to emit a first laser beam into the liquid flow of the sorting device, where the first laser beam and the liquid flow intersect at a first laser reference point located in a nozzle system of the sorting device, a second laser source configured to emit a second laser beam into the liquid flow, where the second laser beam and the liquid flow intersect at a second laser reference point located outside the nozzle system, and a droplet delay time calculation unit configured to calculate the droplet delay time.

A tachymeter device for indicating an average speed of a moving object and a wristwatch comprising such a tachymeter device comprise a timer and an activator for manually starting the timer, when the object passes a starting mark, and stopping the timer, when the object passes a defined distance from the starting mark. They further comprise a housing, a scale for indicating an average speed of the moving object and a pointer for indicating a measured average speed on the scale, wherein the measured average speed is derived from said defined distance and a time to cover said defined distance measured by the timer. The scale is designed as a scale part that is arranged detachably at the housing. The scale part is selected from a set of scales parts comprising a plurality of differing scale parts each having a scale with speed indication for indicating speed ranges corresponding to differing pre-defined distances.
