Part Number: TDC1000-GASEVM
Tool/software: WEBENCH® Design Tools
In the beginning I am sorry for my bad english.
I have a tdc1000-gasevm board and sensors with the following features:
I want to make a gas flow meter.I uploaded the file generated by the webench designer in the tdc1000-7200 software. In the picture below, you can see my settings:
The tdc1000-7200 software seems to require 49 parameters, but the number of parameters within the generated file is 46.
I realized that these parameters are TDC1000-HV_BST_PWR_EN ,HV_BST_PWR_EN_Period ,FWD2REV_FLOW_DELAY
I entered these parameters manually:
I placed the sensors at a distance of 10cm:
I put jumpers in the following way:
In the csv file, the numbers for the start_to_stop1 column have been severe changes (no flow exists)
Results based on start to stop1.xlsx
So I chose start_to_stop2 in the tdc_select. The chart is as follows. But when I was flowing through the sensors with a hair dryer, there was no change in the chart
Results based on start to stop2.xlsx

please guide me:
1)What is the proper setting for my system?
2)What is the reason for the dramatic changes in data
3)Why online software does not generate 49 data for gas flowmeter
4)In the csv file, the sound speed is 1404 m/s. How can I change it to the speed of sound in the air or other fluids?
5)Why are the start_to_stop1 column numbers larger than the corresponding numbers in the start_to_stop2,3,... columns, and the start_to_stop1 numbers have severe changes, whereas start_to_stop2 numbers do not have significant changes (even with the flow by the hair dryer)
6)I thought it was better to have a column for the date and time of the samples in the csv file.
With special thanks
