Principle Introduction:
Winsen Electronics produces F1031 micro flow sensor, adopting thermodynamic principle to detect the gas flow.
F1031 micro flow sensor adopts thermodynamic principle to detect the gas flow, and it has high accuracy and good repeatability. The built-in temperature sensor makes the product has the function of professional temperature compensation calibration. At the same time, the output is linear analog voltage which is convenient to use.

Note:

①The measuring range within 20-200SLM is available and regular measuring ranges such as 20、35、50、100、150、200SLM.Customized fee will be charged for other ranges.
②SLM means standard liter per minute. Standard-state: gas temperature is 0℃ and pressure is 101.325 kPa.
③The testing environment is room temperature and clear air.
④If higher pressure range is needed, please fix the four screw holes on the back of the sensor. 
⑤The temperature compensation is for the tem. range of 0-50℃ and the compensation performance can’t be ensured beyond the temperature range.
