Water Flow Sensor YF-B7

SKU
114991177
It consists of a copper body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal.

Water flow sensor consists of a copper body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. This one is suitable to detect flow in water dispenser or coffee machine.

Life is longer than plastic body.

Features

• Compact, Easy to Install

• High Sealing Performance

• High Quality Hall Effect Sensor

• RoHS Compliant

  • How many pulses per liter does the Water Flow Sensor YF-B7 output?
    Question by: Eduardo Vazquez on 2019-09-09 15:54:50

    Hi there~, If 1L water pass through, it will generate 11*60=660 pulses.  thanks.

  • Refering again to YF-B4/7 what is the type of temp sensor and value of resistance vs temperature. From what i managed to find on internet it is 50kOhm at 25 degrees Celsius. I need 10kOhm at 25 deg Celsius. So again what is part no of original temp sensor?!

  • Can you please upload any kind of datasheet for Water Flow Sensor YF-B7 and YF-B4 especially sizes of the thread...
    Question by: Piotr Podkowa on 2019-07-16 13:57:02

    Hi there~, They share the same spec and most of the parameters are the same. The only difference between YF-B7 and YF-B4 is the mechanical drawing. You can refer to mechanical drawing for the differences. Here is the link. thanks. https://github.com/SeeedDocument/Water-Flow-Sensor-datasheet

  • What is the main difference between YF-B1 and this YF-B7? Does it support the same water pressure? How many pulses does this model produce per liter? Thanks
