Hoffer Supplies Sanitary Flowmeters for “Bag-in-a-Box” Beverage Industry [Application Note]

Published by   – January 27, 2016

Thousands of bag-in-a-box beverage containers are filled daily throughout the country and total millions of gallons per year. These boxes are, in turn, distributed to wholesaler operations and various “fountain” sales groups.


Hoffer Flow Controls turbine flowmeters play a key role in many of the bag-in-a-box production plants throughout the beverage industry. Their Sanitary Series, sanitary turbine flowmeters, along with a batch controller are used to batch a specific amount of the beverage product into a container. The typical filling process incorporates a conveyer system and a filling station. The Hoffer turbine flowmeter has been used to batch numerous beverages including concentrated Coca-Cola syrup. In this application, two flowmeters are used for batching one part concentrated syrup to five parts water.

In addition to metering the beverage product, the turbine flowmeters are exposed to regular “clean in place” (CIP) scenarios. The filling station may be cleaned with hot water, steam, or a suitable CIP fluid including caustics and acid based solutions. The flowmeter design and materials must be suitable for the filling application, as well as, the cleaning cycles that the meter will be exposed to. Depending on the application, the flowmeter could be cleaned as many as six times per day.

Many filling production operations run multiple shifts.Their production cycle may include filling two to three containers per minute. This can translate to 2880 “batches” per day through a single flowmeter! The flowmeter design must be robust to withstand the service environment. Additionally, the flowmeter should respond rapidly in the service environment to assure an accurate batch.

One of Hoffer's satisfied customers includes a Coca-Cola bag-in-a-box beverage production facility located in the Pacific Northwest. They use Hoffer meters for batching water and various syrup products. This location is one of five Coca-Cola production plants nationwide. They produce 10,000-12,000 packages per day or 12.5 million gallons per year. They have used the Hoffer Sanitary meters for several years. The Hoffer meter replaced another turbine flowmeter that they were experiencing problems with. The primary issues that drove this location to select Hoffer include the rapid dynamic response of the flowmeter and the ability to withstand the CIP cycles. Previous meters employed were not as responsive and exhibited pickup coil failures from the thermal cycling that the meter is exposed to during the CIP cycle.

Hoffer is pleased to provide accurate flow measurement systems to help meet the criteria of another challenging application.
