Nico 15/30 - Radar sensor for continuous level measurement of bulk materials

  • continuous measurement
  • also under difficult process conditions
  • can be used on a wide range of different materials
  • for level measurement in vessels up to 15 m and 30 m height

Use

The Nico 15 and Nico 30 radar sensors have been designed to continuously measure the level of materials in storage vessels under difficult process conditions.They can be used on a wide range of different materials having varying particle sizes and compositions. The measurement is unaffected by dusty atmospheres, obstructions or temperature variations.

The Nico 15 measuring range is 15 metres and the Nico 30, 30 metres.

The good signal focus ensures that vessel fittings and encrustations on the walls does not affect the measurement.

Function

Extremely short microwave pulses are transmitted via the antenna system, to the material to be measured, the pulses are reflected by the surface of the material, and received back to the antenna system.
The time taken between the transmission of the pulses and receiving the pulses,
is proportional to the level in the vessel.

Because the pulses are travelling so fast, and difficult to process, a procedure is adopted to allow for the processing of the pulses. The pulses are transmitted in the K-band frequency range, where its usage is time proven.
The transmitted power is well below the IEC specifications. There is no need to calibrate the vessel whether empty or full.

Mounting and Installation

Measurements with flange installation

The Nico 15 is supplied with a DN 80 flange, which is installed on the vassel using an identical flange.

 

 

Measurements using the pivot-mounted bracket

If it is not possible to install the sensor in the centre of the silo, it can be directed towards the centre using an optional pivot-mounted bracket.
The illustration below provides a simple overview of how to determine the required angle.

 

 

Measurements with installation arm

The installation arm allows the sensors to be installed easily on the silo wall or roof.  
This is a very simple and effective method to direct the sensor towards the surface of the bulk goods, particularly for open silos.

 


Operation

The display and control module must be used to calibrate the sensor.
The plug-in module is used to display measurements and for control and diagnostic purposes. It features an illuminated display and appropriate control keys.
