FILLING-LEVEL MEASUREMENT DEVICE AND METHOD FOR MEASURING THE FILLING LEVEL ACCORDING TO THE PROPAGATION TIME PRINCIPLE

摘要

The invention discloses( 5 )It is input to fluid level measuring device,Packing material is filled for measuring( 1 )Container,And for being input to level gauging level measurement equipment by described( 5 )It can be used for measuring the reliable of material position and directly autonomous mode in restarting,Including at least one antenna( 11 ),Signal is transmitted for sending(Sulphur)With reception echo E,Signal processing unit( 13 ),For exporting echo function from received echo-signal( E )Therefore,Include amplitude(One)Echo-signal,According to the propagation time,Memory( 17 ),Whose column for data in storage container appropriate cards,For distinguishing reception of echoes function,Thus echo function column correspond to fill level and the corresponding echo function for specific grade of entering in single file,It further include assessment unit( 19 ),Its accessible table,So that it is determined that material position.
