Functional principle

Determination of the height of the dip tube by an ultrasonic sensor

• Sonic impulses run through the tube that is filled with the product up to the liquid's surface, are reflected there and return to the sensor within milliseconds. 
• The duration of the impulse is measured with high accuracy.

Reference measurement by using a reference pipe

• Patented process, identifying the specific sonic´s speed of the loaded goods and its temperature.

Calculation of the volume

• by means of the dip table, determined at the calibration, with a meassuring uncertainty < 0.1%.

Wave movements

• Registration and analysis of troubles caused by waves at the product surface by using the appropriate software.

Identification of remaining product

• Product detectors installed in the delivery line system determine the quantity in the delivery lines and take it into account in the volume balance. 
• SEAL can also detect quantity deviations.

Density measurement

• Measurement of the product density and identification of product contamination
