PROBLEM TO BE SOLVED: To provide a flowmeter which has temperature variations in flow rate compensation coefficient and zero-flow-rate offset compensated.SOLUTION: An instrument electronic device 20 for geometric heat compensation includes an interface 23 which receives a sensor signal 31 and a temperature signal (T) 32 of a flowmeter, and a processing system 24 which computes geometric heat compensation coefficients (TFe) 45 of one or more conduit lines using the temperature signal (T) 32. The geometric heat compensation coefficients (TFe) 45 are used to process a first and a second sensor signal. |
