Title:
EQUIPMENT FOR MEASURING GAS FLOW RATE
Document Type and Number:
Japanese Patent JP3709385
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain equipment for measuring the gas flow rate in a suction passage for sucking gas in which abnormal output, aging, contamination and damage of a flow rate measuring element due to liquid and foreign matter existing in the sucked gas are reduced.
SOLUTION: The gas flow rate measuring equipment having a flow rate detecting element located in the suction passage for sucking gas and detecting the gas flow rate comprises a subchannel for taking in the gas flowing through the suction passage, a subchannel inlet part opening toward the upstream side in the main flow direction of gas in the suction passage, and the flow rate detecting element located in the subchannel.
