    What is a flow meter

    Mark Yes I would like one to use, and learn about. I have a Boris meter too and I use it but the old school stuff is interesting. Let me know what you want for it and your PayPal. It's fun running boats learning about this hobby. Thanks Glenn

    What is a flow meter

    Oh...ok. That makes me think about the system differently. So you have a regulator on the propane tank and adjust until the magnahelix reads 40?. Then adjust the needle and record reading from the flowmeter. Does the magnahelix reading change while you're adjusting the needle or stay relatively constant? i.e. Do you have to adjust the needle, then reset the gas pressure to 40, adjust needle again, then adjust to 40 again...etc? Thanks. Does anyone have one of these meters they would be willing to sell? For some reason, this is all really fascinating to me. Glenn

    Wow thank you. That's super interesting. Looks like you flow gas through the Flowmeter and then through the Carb. The Magnehelic measures differential pressure (dP) between the pressure in the line and atmospheric pressure. I can see that as flow increases the dP goes down and vice versa. I suspect that using compressed gas would be nice because it's always dry where an air pump could push some (small) percentage of water through the system if it's really humid. I bet that using modern day microchips you could measure air density, density altitude, humidity, etc. and compensate to correct for those conditions. But I bet those old meters we're really good - just kinda big. I actually found the Magnehelic and Flowmeter on line. Thanks so much for the information.

    John thanks for the detailed message. Really interesting. A schematic would be great. I'm guessing you flow a fixed (known size) orifice to calibrate, and then go ahead and flow the engine. Wish I was near Alabama.

    I think they were called magnehelic flow meters. Does anyone have a schematic of one? I would like to know exactly how they measure differential pressure and record flow. What does the reference gas do? Got me curious....

    What is a flow meter

    Didn't there used to be flowmeters that used a reference gas like propane and then based on the atmospheric conditions would show the flow with accuracy for those conditions? I think the theory was that you could set the flow and it would run the same at sea level as at 4000 ft altitude, cold days, rain, hot, humid, etc. I never used one but I saw some boaters with tanks, tubes, meters, etc. Seemed like quite a orocess, but probably very accurate. Are today's flowmeters as accurate as those?

    Novarossi 21 backplate size

    I think I have one of your backplates for my 35plus. Do you need a dimension? Which ones?

    Nitro mixing jug?

    Great info - thanks everyone

    Nitro mixing jug?

    How much difference do you think it really makes? Would weight and volume methods be pretty close at standard temperature and pressure? And then maybe differ at high altitude or high heat and humidity?? Here's a random chart from a Google search - the coefficient looks pretty small for methanol, although a big enough temperature change could be significant. I'm thinking that I would generally mix fuel under somewhat constant temperature conditions.....

    Prop Bending Pliers

    Thanks everyone. I just ordered some pliers from Maston's RC Marine. I think they will work well. Alan your stuff looks really nice - I may contact you on the anvil and gage.

    Nitro mixing jug?

    Exactly Ron. Makes it super easy and accurate to mix fuel. Do 3 cylinders full and get over 3/4 gallon.

    Nitro mixing jug?

    I use a 1000 ml graduated cylinder. No top but I can pour it into a can (through a filter) right away... Do a Google search if it might work for you

    Prop Bending Pliers

    Hi everyone. I was wondering what do you use to bend props like if they get dinged up or the tips bent for some reason. Do you use those round nose needle nose pliers? Thanks Glenn

    John Albritton you have a PM

    Just trying this forum out. John if you read this, please check your messages. I'm looking for a throttle arm. Thank you Glenn
