What is a Flow Meter Used for on a Coffee Machine | Quick Tips

Today we look at Flow Meters for your Espresso machine - Find out what they are and why we need them in our machines
Flowmeters control the flow of water to the group head, only allowing a predetermined amount to pass through.
Basically, they have a star/impeller with a magnet inside, and with each rotation of the impeller a defined amount of water is passed through, and once the amount required has passed a signal is sent to the board which cuts the water supply to the group head by closing the three-way solenoid valve and stopping the pump, and as such it can deliver exactly 30ml (or any other determined amount).
Flowmeters are only used in volumetric commercial coffee machines.

Thanks for watching

[@the38steps]

Thanks for the concise description and how the part functions. Exactly what I was looking for!

Glad it was helpful!

[@masoudnarimisa9260]

great sir..i have a question..some espresso machine for instance bezzera has auto models but with no flowmeter..how they work?? reading time??

[@TomsCoffeeCorner]

Thanks mate! Do these ever get stuck if the machine is too calcified? I have a Bambino Plus that is not pulling any water, although the pump is running. I wonder if the flowmeter is blocked...

[@CoffeePartsTV]

Yes, they can block up with calcification. Descaling machines is an important part of maintenance as not only do they block. up, but things like elements become less efficient, probes doesn't register correctly, etc...

@@CoffeePartsTV I found out what the problem was, upon taking apart the machine. An air pocket had formed from the OPV output to the brew group. I had to prime it manually with a syringe. Cheers!

​@@TomsCoffeeCorner would you mind explaining how you did that I have the same machine with the exact same issue

[@mustajabquliyev2309]

Hi friends can anyone help what price range are these flowmeters?

[@kbumb]

I'd like to know, while assembling these flow meters, does orientation have an effect on accuracy? Like the YFS201, its turbine part should be facing up or down? How are these flow sensors generally oriented?

I got seaco incanto hd8914 and i have a code 5 error. I chanced the water pump but still i have same issues. Any idea?
Thx!!!

What I'd like to see is a cost break-down of parts like this and the required electronics. My impression is that features like this are extremely overpriced when you look at the simplicity of the device. Same with the different types of boilers, pumps, and overall build quality of liquid and electrical connections. I seriously fail to see why a machine in the $700 range isn't top-of-the-line other than people are stupid and pay thousands of dollars for relatively simple machines.
