Double Counter

Blasenzähler

CO2 bubble counters allow you to monitor the flow rate of CO2 into your aquarium. Being able to visually monitor the CO2 flowrate helps detect possible drifts due to faulty regulators or needle valves. The bubble counters are attached inline with the CO2 line and secured to the outside of the aquarium. Typical bubble counters allow the user to monitor CO2 flowrates up to 4-5 bubbles per second. Flowrates higher than this makes counting, and therefore monitoring, difficult to impossible. Cal Aqua Labs' Double Counter addresses this issue by offering a unique dual-function design that allows monitoring of both low and high CO2 flowrates within one unit.

Double Check

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.

More information, including how to relate the high-flow bubble rate to the normal-flow rate, can be found in the FAQ section.
Note: Always install a check valve below the bubble counter to prevent water from flowing back into the regulator.

Each set includes 2 suction cups.

Approximate size of the Double Counter: 9.5cm x 1.7cm (LxW)

The unique funnel design allows larger bubbles to be formed, thus slowing down the bubble rate and allows high CO2 flowrates to be easily monitored.

The normal-flow configuration (with the broadening downwards) produces regular-sized bubbles for monitoring of low CO2 flow rates.
