During work on and with the device the required personal protective equipment must always be worn. Appropriate use VEGAPULS WL 61 is a sensor for continuous level measurement. You can find detailed information about the area of application in chapter "Product description".
When installed within 4 to 40 km of a radio astronomy station, the instrument must not be mounted higher than 15 m above the ground. You can find a list with the respective radio astronomy stations in chapter "Supplement". VEGAPULS WL 61 • Profibus PA...

Principle of operation Application area The radar sensor VEGAPULS WL 61 is the ideal sensor for all appli- cations in the water and waste water industry. It is particularly suitable for level measurement in water treatment, in pump stations as well as storm water overflow tanks, for flow measurement in open flumes and for gauge measurement.

The instrument is normally mounted with a strap vertically on the mounting ceiling. This ensures swivelling of the sensor up to 180° for optimum orienta- tion. Fig. 4: Ceiling mounting via the mounting strap with length 300 mm VEGAPULS WL 61 • Profibus PA...

300 mm Flange mounting For mounting the instrument on a socket or a manhole cover, an unassembled combi collar flange for DN 80 (ASME 3" or JIS 80) is optionally available also as retrofitting part. VEGAPULS WL 61 • Profibus PA...
By turning the instrument in the connection flange or mounting strap, the polarisation can be used to reduce the effects of false echoes. The position of the polarisation is marked by marking bars on the instrument. VEGAPULS WL 61 • Profibus PA...

Fig. 10: Mounting of the radar sensor on round vessel tops In vessels with conical bottom it can be advantageous to mount the sensor in the center of the vessel, as measurement is then possible down to the lowest point of the vessel bottom. VEGAPULS WL 61 • Profibus PA...

Approximate values of the socket heights are shown in the following illustration. The socket end should be smooth and burr-free, if possi- ble also rounded. After mounting, you have to carry out a false signal memory during the parameter adjustment. VEGAPULS WL 61 • Profibus PA...
Page 17
Make sure when planning your measuring site that the radar sensor has a "clear view" to the measured product. In case of existing vessel installations, a false echo storage should be carried out during setup. VEGAPULS WL 61 • Profibus PA...

As soon as a plausible measured value is found, the corresponding current is outputted to the signal cable. The value corresponds to the actual level as well as the settings already carried out, e.g. factory setting. VEGAPULS WL 61 • Profibus PA...
Device descriptions as Enhanced Device Description (EDD) are available for DD adjustment programs such as, for example, AMS™ and PDM. The files can be downloaded at www.vega.com/downloads under "Software". Adjustment Since a radar sensor is a distance measuring instrument, the distance from the sensor to the product surface is measured.
The echo curve of the setup is stored via: • PC with PACTware/DTM • Control system with EDD • Display and adjustment module VEGAPULS WL 61 • Profibus PA...
Maintenance: Due to external influences, the instrument function is limited. The measurement is affected, but the measured value is still valid. Plan in maintenance for the instrument because a failure is expected in the near future (e.g. due to buildup). VEGAPULS WL 61 • Profibus PA...
