Safeguarding CO2 Measurements
Monitoring and controlling dissolved CO2 concentrations helps ensure consumers experience the sight and effervescence of your products the way you want them to. This white paper discusses the two main technologies for in-line dissolved CO2 measurement, provides an overview of how those two measurement technologies work and offers a solution to help you maintain control over your production.
Typical applications for in-line dissolved CO2 measurement systems in beverage producing processes are:
As discussed in the white paper, the market for in-line dissolved CO2 measuring systems is dominated by sensors based on two measurement principles.
The major advantage of TC-based sensors is that unlike p/T sensors they have no moving parts. The partial dissolved CO2 pressure determination is acquired by measuring the thermal conductivity of the gas present in a measuring chamber separated from the liquid stream by a gas-permeable membrane. The TC principle is immune to the presence of background gases, which results in high CO2 selectivity. Also, it exhibits high comparability with established reference methods.
With the InPro 5500i dissolved CO2 sensor METTLER TOLEDO has enhanced this well-established principle by improving sensor handling and refining the membrane cap to make exchange quick and easy.
The InPro 5500i incorporates METTLER TOLEDO’s Intelligent Sensor Management (ISM) technology. The ISM concept simplifies sensor handling, enhances reliability, and reduces sensor lifecycle costs. ISM’s features include diagnostics tools that constantly monitor a sensor’s condition. On the InPro 5500i these tools provide an immediate alarm should the required purge gas supply decrease or gas-permeable membrane integrity drop.
Find out in this white paper about the challenges of dissolved CO2 measurement and how the InPro 5500i leads to substantial benefits regarding operation and process uptime.
