Pressure drop over flow sensor YF-B1

Hi!

I require your help regarding a problem I’m encountering.

Can anyone tell me where I can find the pressure drop over the YF-B1 flow sensor for different flow rates?
(Product Code : RB-See-603)
Or has anyone measured it experimentally?

Thank you so much in advance for your help!

Hey!

You can find this information in the datasheet, here:

hey AudioVox

Thanks for the datasheet! Where did you find that value in the datasheet?
By pressure drop, I mean the internal pressure drop (so between the inlet and outlet of the sensor).
And do you know what the meaning is of the MIN and MAX in the table at the last page? is this the minimal and maximal frequency they measured with the corresponding flow rate?

Hey!

The Min / MAX in the table is the Frequency (Hz) related to that flow (liters/min) (with an error margin).

Sensor Frequency (Hz) = 11 * Q (Liters/min)

But we do not have any information concerning the internal pressure drop between the inlet and outlet of the sensor.
