How is the BatchBoy better than a meter?
Four chief reasons: 1) If you use 4 different chemicals, you would need 4 meters. The BatchBoy can handle 4 chemicals (8 total if you add chemical valves to the additional chemical inlet ports); 2) The BatchBoy measures true liquid volume, it does not measure air, it does not care about viscosity; 3) The machine never needs to be calibrated, it will be as accurate 10 years from now as it is today; 4) You can measure very small amounts, down to an ounce, no meter can indicate only an ounce of liquid.
