An apparatus for measuring the flow rate of a fluid with the use of a measurement transducer. A memory containing the measurement characteristics of the transducer as arranged in close proximity to the transducer. A dialogue module is provided in an electronic computer assembly. The dialogue module is capable of initially reading the data of the transducer memory in order to transfer the data to a memory of the electronic assembly. Thereafter the transducer memory is isolated and processing of the measurement signals from the transducer is effected by means of the transducer characteristics transferred to the memory of the electronic assembly.
