Beer and Wine Flow Measurement
Flow measurement of beer and wine is essential in the production, brewing, and distribution process. This ensures accurate flow measurement. Thus, improving product quality and efficiency.
There are multiple steps in the beer brewing process. But there are still some challenges in beer and wine flow measurement.
For example, the viscosity and density of beer and wine vary. This affects the accuracy of the flow meter. If the flow meter material is not specially designed for these applications, the corrosive nature of beer and wine may damage it.
Another challenge is temperature and pressure fluctuations. The flow meter should withstand the temperature and pressure changes that occur during the brewing and winemaking process. Including changes during cleaning with hot water and disinfectants.
Therefore, flow meters need to be calibrated regularly to ensure accurate measurements. Especially when handling different types of beer or wine. Exceptionally, you should ensure that the flow meter is easy to clean. And made of materials that meet food safety standards.
Common Brewery Flow Meter Types
Electromagnetic flow meter
An electromagnetic flow meter, also known as a magnetic flow meter. It uses Faraday’s law of electromagnetic induction to measure the flow of beer and wine. They consist of a non-magnetic insulated pipe and electrodes, and coils for generating a magnetic field.
For example, the ZD10 series small electromagnetic flow meter. It is a new generation of small-caliber electromagnetic flow meter developed by our company. It is specifically designed for small flow rates.
These meters are very suitable for water-based solutions. For example, wort, beer, and brewing water. It can be used in chemical, food, pharmaceutical, and other industries.
Benefits:
- Electromagnetic flow meters typically have an accuracy of 0.2% to 2%.
- They do not clog and maintain the integrity of the liquid. They are ideal for sensitive applications such as brewing.
- They are ideal for sanitary applications due to their sanitary design and ability to handle a wide range of viscosities.
Limitations:
- They are suitable for use with conductive liquids only. This limits their use in certain applications.
- More complex to install and calibrate than simple flow meters.
Turbine Flow Meter
A turbine flow meter measures flow based on volumetric flow. It uses a rotor that rotates at a speed proportional to the flow rate of the fluid passing through it. A magnetic sensor counts the rotations to determine the flow rate. The data is then converted into a flow measurement.
Turbine flow meter offers high accuracy and the ability to measure flow rates in a variety of brewing and winemaking processes. It is ideal for measuring large volumes of beer, wort, and water. It provides reliable measurements for your brewing application.
Benefits:

- Its cost is relatively low compared to Coriolis or magnetic flow meters.
Limitations:
- Although turbine flow meters have moving parts in contact with the fluid, their pressure drop is not significant.
- Their moving parts may wear and require regular maintenance.
- Not suitable for high viscosity or slurry liquids.
Ultrasonic Flow Meter
An ultrasonic flow meter uses sound waves and the transit time principle to measure fluid flow rate. It usually does not need physical contact with the liquid. It can be remotely mounted with the transmitter. Clamp-on ultrasonic flow meter can be applied to a variety of liquid applications.
This includes ultrapure liquids, water, chemicals, raw sewage, recycled water, cooling water, river water, factory wastewater, alcohol, beer, etc.
Benefits:
- Ultrasonic flowmeters are easy to install. They are available in clamp-on, handheld, and portable designs.
- Accuracy is typically between 0.7% and 1%.
- Non-invasive measurement, flow can be measured without direct contact with the liquid.

Limitations:
- Ultrasonic flow meters may not be suitable for high viscosity fluids.
- Ultrasonic flow meter installation generally requires a straight pipe.
Positive Displacement Flow Meters
Positive displacement flow meters, also known as volumetric flow meters. It can capture and measure a specified volume of liquid and count the number of times that volume is displaced to measure flow. This makes them suitable for accurately metering raw materials or small batch brewing.
Benefits:
- Positive displacement flow meters are extremely accurate. Especially at low flows.
- They can be used with high viscosity, dirty, and corrosive fluids. And require virtually no straight pipe runs to regulate fluid flow.
- They are highly repeatable. Purely mechanical versions require no external power source to operate.
Limitations:
- Moving parts may cause wear.
- More frequent maintenance may be required.
A Gear Flow Meter
A gear flow meter is a typical positive-displacement flow meter. It is a high-precision transmitter used to measure volume flow. Compared with the oval gear flow meter, the GF series gear flow meter has more advantages in measuring small flow. It is available in aluminum alloy and stainless steel.
