| description | Disclosed is a measurement pickup for determining the mass flow rate of a liquid comprising: at least one measurement tube for carrying the liquid having an inlet-side end section and an outlet-side end section; a support body on which the measurement tube is mounted an exciter for exciting vibrations of the measurement tube; at least one vibration sensor for detecting vibrations of the measurement tube; an operating and evaluation circuit for driving the exciter, for receiving the signals of the vibration sensor, and for ascertaining a measured value representing the mass flow rate. The operating and evaluation circuit comprises an adaptive low-pass filter for filtering the sequence of measured values representing the mass flow rate, wherein the low-pass filter has at least one filter parameter dependent on at least one adaptive controlled variable that, for its part, is dependent on the gas content of the test medium. |
