Abstract
A fluid flow meter serves to determine a flow of a fluid, in particular in a form of gas, in a pipe, wherein the fluid flow meter is configured to generate a first measurement variable and at least one second measurement variable for the fluid, and to generate at least one first diagnostic parameter. The fluid flow meter comprises a diagnostic system that is configured to determine a first threshold value for the at least one first diagnostic parameter based on the first measurement variable and the at least one second measurement variable, and to output a first message to a higher-ranking control device when the at least one first diagnostic parameter reaches said first threshold value.
Claims21
A fluid flow meter to determine the flow of a fluid in a pipe,
- wherein the fluid flow meter comprises a measurement device having first and second transmission and reception units which transmit and receive ultrasonic signals to and from each other, so as to generate a first measurement variable and at least one second measurement variable for the fluid, and to generate at least one first diagnostic parameter,
- wherein the fluid flow meter further comprises an acoustic sensor to sense acoustic signals (dB) from a disturbance of the fluid in the pipe so as to generate the at least one first diagnostic parameter comprising the sensed acoustic signals (dB),
- wherein the fluid flow meter further comprises a diagnostic system that comprises a trained AI module to determine a first threshold value for the at least one first diagnostic parameter based on the first measurement variable and the at least one second measurement variable, and
- the diagnostic system outputs a first message when the at least one first diagnostic parameter reaches said first threshold value.
A method for operating a fluid flow meter that is configured to determine the flow of a fluid in a pipe, wherein the method comprises the following method steps:
- using the fluid flow meter comprising a measurement device having first and second transmission and reception units which transmit and receive ultrasonic signals to and from each other to generate a first measurement variable and at least one second measurement variable for the fluid, and to generate at least one first diagnostic parameter, wherein the fluid flow meter further comprises an acoustic sensor to sense acoustic signals (dB) from a disturbance of the fluid in the pipe so as to generate the at least one first diagnostic parameter comprising the sensed acoustic signals (dB);
- using a diagnostic system comprising a trained AI module to determine a first threshold value for the at least one first diagnostic parameter based on the first measurement variable and the at least one second measurement variable;
- wherein the diagnostic system outputs a first message to a higher-ranking control device when the at least one first diagnostic parameter reaches the first threshold value.
