Title:
CONNECTING PIPE FOR DIFFERENTIAL PRESSURE TRANSMITTER
Document Type and Number:
Japanese Patent JPH04328435
Kind Code:
A
Abstract:
PURPOSE:To detect the clogging of a connecting pipe for leading out fluid pressure from an object to b.e measured into a differential-pressure transmitter. CONSTITUTION:In a connecting pipe for a differential-pressure transmitter which introduces fluid to be measured from an object to be measured and sends the fluid into the differential pressure transmitter 23, at least two valves which are connected to the connecting pipe and flow-speed sensors 40 and 42 which are arranged at the specified positions of the connecting pipe are provided. The clogging of the connecting pipe is detected based on the flow speed signals, which are generated by the flowing of the fluid to be measured into the flow- speed sensors, by operating these valves. This is the connecting pipe for the differential pressure transmitter.
