Foam on beer detectors, commonly referred to as FOB devices, are integral components we frequently install in coolers. Their purpose is to detect when a keg is empty and automatically halt the flow of beer. By doing so, these devices prevent the wasteful release of gas and spitting beer from the taps. Furthermore, when a fresh keg is connected to the same line, the foam on beer detector ensures that the newly tapped beer is preserved and poured without excessive foaming. By having a foam on beer (FOB) device installed on your beer line, you can greatly reduce foaming issues when your keg runs empty. Additionally, when you tap a fresh keg, your tap will pour immediately without delay. This means minimal foam waste, no interruption in service for your customers, and the elimination of labor costs associated with employees having to clean up a messy cooler caused by an empty keg blowing. Ensure your staff understands the ins and outs of a foam on beer detector. FOBs, as draft components in bars and restaurants, are often misunderstood. New employees and managers may be tasked with keg changes without knowing how to reset a FOB. It is crucial to provide proper training to the staff on understanding and operating these devices effectively. Maintenance is an important aspect to consider when it comes to FOBs. Just like other equipment, FOBs can become dirty and sticky due to being filled with beer. This can make them challenging to reset. Moreover, if the bleed valve (vent) becomes excessively dirty, it may stick in the open position. In such cases, there is a risk of inadvertently bleeding an entire keg and losing all the product contained within it. For customers with long-draw or through-the-wall draft beer systems, we strongly recommend the use of FOBs. These devices offer an affordable solution to effectively manage shortages in your bar, ensuring a smooth and uninterrupted beer service. As with any beverage dispensing equipment, we at Glacier Design would be happy to install or regularly maintain the systems that will take your establishment to the next level. Foam on Beer Detector FAQs What is a foam on beer detector? A foam on beer detector is a device used in the beverage industry to monitor and control the amount of foam that forms on the surface of beer or other carbonated beverages. It helps maintain consistent pouring and serving standards by preventing excessive foam or overflow. How does a foam on beer detector work? A foam on beer detector uses various sensing technologies, such as ultrasonic or capacitive sensors, to measure the level of foam present on the surface of the beer. These sensors detect the difference in density between the liquid and foam, allowing the device to accurately determine when the foam reaches a specified level. Why is controlling foam important in beer service? Controlling foam in beer service is essential for several reasons. First, excessive foam reduces the volume of liquid in the glass, leading to inconsistent portion sizes and potentially affecting customer satisfaction. Second, foam affects the aroma, taste, and appearance of the beer, and maintaining the right balance ensures an optimal drinking experience. Lastly, excessive foam can lead to spillage, resulting in wastage and potential safety hazards. Can foam on beer detectors be used for other carbonated beverages? Yes, foam on beer detectors can be used for other carbonated beverages beyond beer. The technology and principles behind foam detection can be applied to soft drinks, sparkling water, cider, and other carbonated beverages to ensure accurate pouring and consistent quality. Are foam on beer detectors suitable for all types of beer? Foam on beer detectors can be adjusted and calibrated to accommodate different beer styles and carbonation levels. By setting appropriate thresholds, the device can effectively detect and control foam formation, regardless of the beer type, be it lagers, ales, stouts, or other styles. Can foam on beer detectors be installed in existing draft systems? Yes, foam on beer detectors are designed to be compatible with existing draft systems. They can be easily integrated into the dispensing setup, typically positioned near the faucet or the beer line, without requiring extensive modifications. Are foam on beer detectors easy to maintain? Foam on beer detectors are generally low-maintenance devices. Regular cleaning of the sensors and periodic calibration to account for any changes in the system are necessary. However, manufacturers provide clear instructions and guidelines for maintenance, making it relatively straightforward for operators. Do foam on beer detectors require any specific power supply? Most foam on beer detectors operate on low-voltage DC power, typically in the range of 12-24 volts. This makes them compatible with commonly available power sources in commercial beverage dispensing systems. Can foam on beer detectors help save costs for bars or restaurants? Yes, foam on beer detectors can help save costs for bars and restaurants in several ways. By reducing foam and spillage, they minimize beer wastage and increase overall profitability. Additionally, they contribute to consistent portioning, preventing over-pouring and saving on beverage costs in the long run. Are foam on beer detectors a common feature in the industry? Foam on beer detectors have gained popularity in the beverage industry, particularly in bars, restaurants, and other establishments serving draft beer. They are increasingly recognized as a valuable tool for ensuring consistent beer quality, customer satisfaction, and operational efficiency.
