Brite Tank CO2 Flow Control - IMPACT MF Flow meter
Controlling the flow of carbon dioxide for optimal carbonation
Successful carbonation of beer using a brite tank is a balancing act between carbon dioxide gas feed rate, pressure and bubble size from the carb stone. Gas flow rate has to be set at a flowrate that would allow the gas bubbles time to absorb into the cold beer before they reach the headspace. If the flow rate is set high the gas will pressurize the headspace. Too a flow and the time required for carbonation increases.
IMPACT MF FLOW METER – This digital flowmeter is ideally suited for controlling the flow of carbon dioxide gas to the carb stone. The flow rate has to be balanced against the pressure in the head space. It can operate at the elevated carbon dioxide feed pressure.
DIGITAL FLOW TECHNOLOGY –At the heart of the MF is a semiconductor gas flow sensor that accurately measures flow at elevated pressure. This battery powered meter displays instantaneous flow and total carbon dioxide delivered during the carbonation cycle.
NEEDLE VALVE– A precision needle valve upstream of the flowmeter is used to precisely adjust the flow into the Brite tank.
PROBLEMS USING VA METERS – VA meters using a ball in a clear tube has been a common solution for carbon dioxide flow control. VA meters calibrated for air at an atmospheric pressure exit pressure will not accurately measure carbon dioxide gas at the elevated pressure used for carbonation.

The Impact MF is a cost effective tool for controlling the flow of carbon dioxide into a Brite tank and will pay for itself in shorter carbonation times.
