When using a differential pressure flow meter to measure flow rate, if the output of the differential pressure transmitter (without taking the square root) is fed directly to the display instrument, the relationship between the indicated value and the flow rate is ＿＿＿＿＿. The scale of the display instrument is ＿＿＿＿＿. If the differential pressure transmitter has a function to take the square root, then the relationship between the indicated value and the flow rate is ＿＿＿＿＿, and the scale of the display instrument is ＿＿＿＿＿ scale.
