FIELD: measuring equipment.
SUBSTANCE: group of inventions relates to measurement equipment, in particular to vibration meters of liquid or gas flow rate. Electronics (20) of the meter includes band-rejection filter (26) connected with possibility of data exchange with unit (10) of the sensor. Band-rejection filter (26) is configured to filter sensor signal from sensor assembly (10) in vibration meter (5). Received sensor signal from sensor unit (10) consists of first component at resonance frequency of sensor unit (10) and second component at non-resonance frequency, wherein the band-rejection filter passes the first component and virtually suppresses the second component, wherein the first component is passed virtually with zero phase shift.
EFFECT: invention discloses an electronic part of a vibration meter, as well as a method of filtering a sensor signal in a vibration meter using a rejection filter.
