is it possible to connect the sensor to a pvc pipe 3/4'' system ?

what the code to get temp value on this built-in temperature sensor?
JaneYu Since this sensor is designed as an analog voltage output, at the same time this voltage can only represent the gas flow rate.
So there is no way to get the value of the built-in temperature sensor. The temperature sensor can only be used for temperature compensation of gas flow values.
I execute the code from this website：

It's data shows about 190~200 slm ,when I do nothing to the sensor.
Is that normal?
Do I need to do any calibration to get the accurate value?
JaneYu Since the sensor is an Analog sensor.
Our sample code is using the analog specification of the Arduino UNO.
So if you are using the 3.3V board (like ESP32), you have to modify the corresponding parameters in our sample code.
How do you get it to measure in both directions? I have only acquired values in one direction using the provided code
JaneYu The sensor interface has a minimum diameter of 21mm and a maximum of 22cm. It cannot be connected to 3/4” pvc pipes.
