With the needle valve fully open and externally limited flow, the flow measurement is stable and the readings plausible. Sadly, when I try using the valve to adjust flow rate, the ball starts vibrating rapidly and tends to get "stuck" at some level. This makes the readings completely unreliable.

I used this flowmeter to make an instrument to measure breath flow and pressure. The control valve is useful to set the back pressure and the floating bead measures a good range of useful flow. It's probably possible to breath out air faster than this device can measure, but that wasn't necessary for my use. Pressure was measured with a pressure gauge, a different Amazon purchase.It seems to work well and is of sturdy construction.

Lo utilicé en cuanto llegó con 2 bombas de aire de 38 L/min que también compré y el medidor de flujo en ambas bombas marca como máximo, menos de 8 L/min. Me hubiera gustado que viniera con un manual de uso para saber la función de la perilla o saber si tengo que hacer algún ajuste a las tuercas.
