Abstract
PURPOSE: To accomplish a highly accurate compensation by making such a construction with the use of a memory type frequency divider that the output pulses of an A/D converter are not neglected but calculated.
CONSTITUTION: A memory type frequency divider 9 is arranged between an A/D converter 8 and a counter 10. As a result, the pulse signals from a flow transmitter 4 are fed through a frequency divider 6 and a delay circuit 7 to the A/D converter 8, which is operative to convert the temperature detected by its sensor 3 into preset pulse signals, so that they are converted into preset pulse signals, and are fed to the memory type frequency divider 9 while their spare pulse signals during the frequency division are being held. Moreover, the output pulses of the divider 9 are fed to and counted by the counter 10, and the counted signals are temporarily recorded in a memory 11 and then fed to an adder 13 through a multiplier 12 so that they are added.
