Dissolved Oxygen Measurement for Craft Breweries

Oxygen is both friend and enemy to the brewer!

It gives yeast what it wants to breathe and survive during the fermentation process and then becomes your main antagonist after the yeast has done its job.

Any process or transfer where beer becomes exposed to oxygen post-fermentation is an opportunity for oxygen to cause staling, muting, and shelf-life reduction. One example is the packaging process. The added oxygen resulting from placing the beer in cans, kegs, or bottles can affect the final product's consistency and taste.

As a brewer, you want to concentrate on producing the best-tasting beer. Therefore, it is critical to know how oxygen affects the brewing process and how packaging can eventually impact your beer's taste. It will give you the trust you need to create award-winning flavors that customers will enjoy, no matter how long the beer sits on the shelf.

METTLER TOLEDO Process Analytics offers the most accurate and cost-effective solutions for measuring dissolved oxygen in brewing applications. These robust optical dissolved oxygen sensors are durable and require minimal maintenance.

Eliminate Delayed Oxygen Measurement Safety Risk in Your Process Gas Analyzer

Having a car alarm that goes off 15 seconds after a break-in puts you at risk of property damage and significant loss. If you wouldn't take this risk with your car, why take it in your process plant?

If you're using an extractive oxygen analyzer that requires sampling and conditioning to prevent explosive conditions, that's exactly what you're getting - an alert up to 60 seconds after an oxygen build up is started. Using an extractive analyzer that requires sampling and conditioning means it's impossible to get real-time information. Measurements are delayed by up to a minute as the sample travels through pipes to the analyzer. In addition oxygen in the sample can be diluted by the gas ahead of and behind it, resulting in a falsely flat excursion curve. An alarm threshold may not be met when it should, so you get one, perhaps inaccurate, result in one minute.

Eliminate the risk. Get continuous real-time measurement. The GPro 500 tunable diode laser gas analyzer from Mettler-Toledo measures in-situ, without the need for sampling and conditioning. It provides continuous measurement and safety-critical applications, so you'll know about oxygen excursions immediately. Don't leave your plant safety up to delayed measurement. Rethink safety. Rethink gas analytics.

Analytical Measurement Solutions for Optimization of Your Brewing Process

Stages of brewing and areas for process measurement.

The beer market is currently experiencing an intense globalization process, reflected in escalating competitive and cost pressures. In addition to this, there is growing diversification into new, innovative beverages that demand maximum production flexibility. The time to market is becoming ever shorter, and product quality has to be guaranteed at a consistently high level, accompanied by an increase in productivity.

In-line Measurements in the Brew House

Proper process control plays a vital role in determining the flavor, foam stability, and color of the finished beer. The relative measurement sensors are exposed to high temperatures, and solid particles and turbidity constituents, and must be capable of surviving multiple CIP cycles.

Turbidity Sensor

Measurements in the Fermentation and Storage Cellars

At standard fermentation temperatures, propagation of microorganisms is detrimental to the beer. In order to prevent this from occurring, hygienic plant design and use of materials resistant to CIP solutions are important criteria, as they are for in-line sensors.

DO and CO2 Sensors

Measurements in CIP Systems

The economic use of fresh water, as well as the multiple use of cleaning solutions, present a further basis for achieving overall cost reduction in line with the strive for greater efficiency of the brewing process. Here also, in-line systems are of help in monitoring and optimizing the relative sub-processes.

Measurements in Wastewater Treatment Facilities

Fouling of sensors in wastewater leads to uncertainty about the measurement results and can even result in measurement system failure. METTLER TOLEDO provides efficient and practical solutions in the wastewater treatment areas as well.

Industrial Corrosion Protection Through Chemical Treatment

"An ounce of prevention is worth a pound of cure", particularly when dealing with corrosion and it's effects on process equipment. Production downtime, safety concerns, environmental damage and personnel health all outweigh the obvious repair and replacement cost of the damaged equipment. All taken, the annual costs due to corrosion are estimated in the process and power industries are estimated to be around $750 billion globally.

Exterior treatments, such as painting and specialized coatings provide satisfactory results to maintain structural integrity. However, internal protection of process equipment requires a different approach. Building equipment from exotic materials which are immune from corrosion exceed any practical concept of reasonable cost. Another, much more reasonable approach is corrosion protection based on chemical treatment.

This guide, courtesy of Mettler-Toledo Process Analytics shows you the role in-line analytics play in keeping corrosion under control and avoiding unnecessary chemicals consumption in chemical plants, refineries, power and Cogen facilities.

Your local Process Analytics specialist can help you select the best equipment and strategy. Their experience and knowledge will save you time, money, and ensure quality. 

Learn How a pH Sensor Works

pH Sensor (Mettler)

The video below will provide you with a basic visual understanding of the design of pH sensors and the principles behind pH probe operation. Before viewing the video, here are some pH basics:

What is pH measurement?

pH (potential of hydrogen) is a figure used to express the acidity or alkalinity of a solution on a logarithmic scale. On this scale 7 is neutral; lower values are more acidic and higher values are more alkaline, with a maximum measurement of 14. In process applications, pH is generally measured with an inline pH probe, the most common being the glass combination electrode. Additionally, an inline pH probe generally requires a process adaption, cable and transmitter.

How does a pH probe work?

A typical combination pH probe is made up of two separate electrodes built into one, a pH sensing electrode, and a reference electrode. In the simplest terms, a pH sensing electrode uses a special pH sensing glass membrane. H+ ions permeate the membrane creating a charge. The potential between the two electrodes is the measurement of hydrogen ions in the solution, giving the measure of pH. For more details, download the free pH Theory Guide.

What is the difference between a pH probe, a pH sensor and a pH electrode?

Absolutely nothing! The three terms are used interchangeably in the industry. They can be used for probes that are used in-process or in laboratory measurement. You may also hear the term "pH meter". This can be used for a piece of laboratory equipment, or the term pH meter can also be used to mean the combination of an inline pH probe, cable and transmitter.
