Cal Aqua Labs Double Counter
(English) The Double Counter functions both as a normal-flow and a high-flow bubble counter in one elegant design. For small to medium-sized tanks where CO2 bubble rates are not as high, the normal flow mode creates bubbles similar to typical bubble counters. This mode can be used to monitor flowrates up to 4-5 bubbles per second. For higher flowrates, simply invert the counter. The tapered design gently guides the bubbles upwards and allows larger bubbles to be formed, effectively slowing down the bubble rate. This allows high CO2 flowrates (up to 10-15 bubbles per second when measured on a typical bubble counter) to be easily monitored.
