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.

GAS / VAPOR EMPTY CONTAINER In a closed (especially outdoor, exposed to sunlight) container, Especially in the case of tanks with a convex or conical bottom, vapors/gases above the liquid can reduce the penetrating ability of or in the case of tanks with equipment (e.g., heating element, the millimeter-wave signal.
– 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.
(henceforth referred to as EView2) according to Chapter 3 in the program's user manual. The software can be downloaded from nivelco.com. Electrical connections: connect the transmitter to the PC using a HART USB modem (accessory supplied separately). Wiring is detailed in Chapter 5.

6. TROUBLESHOOTING 6.1. Status and error indication in HART communication The response code, according to the HART standard, is two 16-bit words after the response code bytes, in the order Errors and Warnings, then Status. If it is ® impossible to query the status and error code via HART , then the indication of the LEDs on the device must be monitored.

The value of one or more parameters is not consistent with the associated parameters. Correct the Parameter table integrity error parameter value. The radar sensor is faulty. There can be several reasons for this, e.g., the data connection with the radar sensor unit is inadequate or insufficient energy available for the measurement.

The threshold can be changed in the Echo diagram window of the EView2 program. In addition, the height of the entire threshold can be adjusted in a simplified way with the P34 "Threshold offset" parameter among the measurement optimization parameters. The main Threshold line is used to trace the general shape of the echo curve.
Caution! The "Cursor On" function does not provide an exact value. It only calculates the value of a given point based on the graphical representation. The threshold highlight can be deleted by selecting its center point, or turning the "Enabled" switch off in the threshold editing function bar, or selecting the "Del current threshold mask"...
