Title:
流量測定装置及び流量測定方法
Document Type and Number:
Japanese Patent JP7198029
Kind Code:
B2
Abstract:
The present invention accurately measures flow rates that have a high peak flow rate caused by pulsation, and is provided with a first flow rate converter 2 having a first measurement range and a first response speed, a second flow rate converter 3 having a second measurement range that is narrower on a low flow rate side than the first measurement range and has a second response speed that is slower than the first response speed, and a flow rate calculation unit 61 that, when a flow rate contained in the second measurement range is measured, calculates the flow rate by correcting outputs from the first flow rate converter 2 using outputs from the second flow rate converter 3.
