The respective scope of delivery results from the orderspecification.3.2 Principle of operationVEGAPULS 64 is a radar sensor for continuous level measurement ofliquids.The small process fittings offer particular advantages in small tanks ortight mounting spaces. The very good signal focusing ensures the usein vessels with many installations such as stirrers and heating spirals.The VEGAPULS 64 is available with different antenna systems:1 2 3Fig. 2: Antenna systems VEGAPULS 641 Thread with integrated horn antenna2 Plastic horn antenna3 Flange with encapsulated antenna systemThe instrument emits a continuous radar signal through its antenna.This signal is frequency modulated in the form of a sawtooth wave.The emitted signal is reflected by the medium and received by theantenna as an echo.The frequency of the received signal always deviates from the actualemitting frequency. The frequency difference is proportional to thedistance and thus to the filling height. This difference is calculatedScope of deliveryApplication areaFunctional principle
