Abstract

PURPOSE: To measure at a high accuracy the fluid pressure of a wide range by converting the pressure of a fluid to be measured into an air pressure by a converter, measuring the air pressure by a manometer and also the conversion error of the converter by a differential pressure converter, and adding the error value and the measured value of the manometer.
CONSTITUTION: A pressure guide tube is fitted to a position to be measured of a pressure vessel 1, and a pressure to be measured is led to the primary side of a converter 2 converting the pressure of a liquid (or a gas) to be measured into an air pressure as it is. Then, the high pressure side of a differential pressure converter 3 having a measuring span is connected to the tube branched from a pressure guide tube guiding the air pressure which is the output of the converter 2 and the low pressure side thereof is connected to a tube branched from the pressure guide tube guiding air pressure which is an output of the converter 2. The output air pressure is led to a manometer 4 where the pressure is measured, and the value totaling the pressure measured by the manometer 4 and the differential pressure measured by a differential pressure converter 3 becomes a pressure sought, and are added at an adder 5.
