Abstract
PURPOSE: To simplify a compensation circuit, by compensating a measured value at a certain temperature to a value at a prescribed temperature and storing the latter value into a memory circuit.
CONSTITUTION: The flow rate of a fluid measured by a flow meter 1 and the temperature of the fluid measured by a temperature detector 4 are changed from analogue values to digital ones so that address signals are produced. The address signals are entered into the memory circuit 3 to pick out a compensated flow rate value stored at an address in the memory circuit 3. The picked-out value is indicated on a digital counter 6 or on an analogue display unit 8 through a D-A converter 7. Therefore, it is not necessary to perform compensation in every measurement. This results in simplifying the compensation circuit.
