Turbine and paddle wheel flow meter
Oct 2, 2022
The focus of this application is the turbine and paddle wheel flow meter.
When choosing it, it was very important to me that it has a high level of accuracy and is resistant to diesel, oil and fuel.
The flow meter I use has a flow range of 0.05 -3.0 L/min and the repeatability of frequency response is +-0.5% (at the same operating condition).
Its port connections are two barbed tube fittings: 6mm.
It works with 5-24V VDC and delivers a signal of 2,500 Imp./L to its 3-pin electrical connection.

I MUST have one of these!! Do you sell them? If not, can you list the components? I like the design too.
First of all, I want to present a construction manual and of course the parts list as well. I'm still looking into the possibility of offering a kit.
When you do, let me know so we can review and promote it!!
I Like.
I'm going to buy these parts, which is also a DIY set. It's great. Thanks for sharing.
Impressive work. I'm excited in following your progress.
is it possible to ad a preassure sensor for tankbags ?
That would certainly work too. The Arduino has even more inputs. Here you only have to choose whether it should be a digital or an analog pressure sensor.
I can't find the right pressure sensor for this application,do you have a hint ?
I'll research what's available on the market
Uwe, did you find any fitting pressure sensor?
Most interested!
Uwe, Thank you. In Ch 2 you noted “ The flow meter I use has a flow range of 0.05 -3.0 L/min and the repeatability of frequency response is +-0.5% (at the same operating condition)”. Can I assume this accuracy is representative of the total volume delivered over time?
I might consider building one using your data. If so, how can one reimburse you for your efforts? Are you considering selling them as a kit?
Thomas, the accuracy is described in the manufacturer's data sheet. I can also say that it is absolutely reliable. You can draw good conclusions from the amounts of fuel refueled after each flight.
I don't offer it as a kit. But you can send me a PM. I'm sure we can find a good solution.
