Another key point to comparing the different flow meters is that as long as the fluidic flow is a continuous flow without pulsation, then the fluidic dynamic will have the system following the Bernoulli equation: http://www.jetec.com w om.tw/ 電話：04-23729418 傳真：04-23724011 Email：sales@jetec.com.tw... -

Therefore, measurement by the meter for a gas medium other than the calibration gas would bear larger measurement errors, particularly at the low Reynold number range where the laminar flow has a sensitive flow profile. http://www.jetec.com w om.tw/ 電話：04-23729418 傳真：04-23724011 Email：sales@jetec.com.tw... -
