Hi Yash, I am not sure I understand what you mean. You mean you are currently able to take 70-80 VFR measurements during the 3-4 second air flow window, and you'd like to increase this to 250-300? If this is the case, you could try reducing your UPS to DNS gap, and UPS0 to UPS1 gap, but at some point these can become too low and result in bad readings or error conditions. You may also want to reduce the number of pulses to reduce the noise in the pipe during and between readings, but if you reduce this too much you will also see reduced measurement quality. If you take a look at the USS Design Center User's Guide , you can find details on the minimum and maximum values for each parameter.
