Water Flow Sensor YF-B4

I bought the Water Flow Sensor YF-B4, and can’t find the Datasheet for the Thermistor that comes with the valve. I was looking to get the Parameters, Beta, A,B,C.
How can I get it ??

Thank you

Hello, and welcome to the forum. I don’t see a datasheet available for that sensor either, but I’m inquiring to get a copy of those specifications from Seeed. We’ll update you once we’ve got an answer from them. Thanks for your patience!
