  • Page 5: Introduction

    Thank you for choosing a NIVELCO instrument! 1. INTRODUCTION Application The new PiloTREK W–200 non-contact radar level transmitters use the most advanced industrial measurement technology, the 80 GHz FMCW radar. The most fundamental advantage of 80 GHz radars compared to lower frequencies (5…12 GHz and 25 GHz) is the smaller antenna size, better focusability, and narrow beam angle.

    – The sensor must be placed in the longitudinal axis of the flume, at a location determined by the characteristics of the flume. This point is marked on the Parshall flumes sold by NIVELCO. – Foam may form on top of the flowing liquid, which may compromise the measurement. Therefore, the liquid’s surface opposite the sensor face must be exposed for a suitable echo.

    4.6. Commissioning and setting up When the device is connected correctly, the radar starts up with a current consumption of 3.5 mA after switching on the power supply. After 3...5 s, the ECHO and the COM LED light up together. After another 5...10 s, the transmitted current corresponding to the operating mode appears on the current output. In this case, the device measures with factory settings.
