<p>In order to provide a thermal flow measurement device with superior measurement accuracy, in a thermal flow measurement device provided with a flow detection unit which measures flow of a fluid to be measured, the flow detection unit has correction means which corrects output of the flow detection unit in a valid flow range capable of being measured with the flow detection unit, wherein the correction means performs the correction so as to achieve a greater sensitivity compared to the sensitivity of the flow detection unit, said sensitivity being corrected so that the output always forms a uniform gradient with respect to the flow. The output is made to be switchable between either voltage output or frequency output.</p> |
