Abstract

PURPOSE:To uniform pressure on the upstream and downstream sides of a variable throttle element and to take a measurement by providing pressure measurement holes, a differential pressure transmitter, a valve opening extent transmitter, etc. CONSTITUTION:The pressure measurement holes 20 and 21 are formed in passage internal wall parts, etc., of a valve main body 2 while facing the upstream and downstream passages 3 and 4 of the variable throttle element 5 in the valve main body 2. Then pressure admitted through the measurement holes 20 and 21 is uniformed and sent to the differential pressure transmitter 22, and then a differential pressure measured value from the transmitter 22 and a valve opening extent value obtained by the valve opening extent transmitter 23 are A/D-converted 24 and further processed by a microcomputer 25. Consequently, its control flow rate is accurately and securely obtained and the flow rate is indicated 27. Thus, the fluid pressure is uniformed on the upstream and downstream sides of the element 5 and accurately measured.
