What Type of Flow Meter Is Used for Milk?

Sanitary Magnetic Flow Meter

A sanitary magnetic flow meter is one of the most commonly used instruments for measuring conductive liquids such as milk. It offers high accuracy, excellent stability, and requires minimal dependence on pipe material or fluid properties. However, in real-world applications, attention should be given to air bubbles or solid particles in milk, as these may affect the measurement accuracy of the electromagnetic flow meter.

Ultrasonic Flow Meter

An ultrasonic flow meter measures flow velocity by transmitting ultrasonic pulses and calculating the time it takes for the sound waves to travel through the fluid. Its non-contact measurement method makes it ideal for dairy applications since it does not interfere with the milk’s properties. However, it can be sensitive to changes in pipe diameter and fluid temperature, which should be considered during selection.

Vortex Flow Meter

A vortex flow meter determines flow velocity based on the vortices generated as the fluid passes through a bluff body. It is valued for its simple structure, low cost, and insensitivity to bubbles or solid particles. However, because milk has a certain viscosity, this can affect the performance of vortex meters, so careful selection is required.

Coriolis Mass Flow Meter

A mass flow meter measures the actual mass flow rate of a fluid passing through the pipe, making it suitable for applications where density variations matter. Since the density of milk is relatively stable, Coriolis mass flow meters can deliver highly accurate measurements. However, they tend to be more expensive than other flow meter types.

In food processing applications, sanitary magnetic flow meters are widely used to monitor and control liquid flow. For example, in dairy processing, electromagnetic flow meters are used to measure the flow of milk and cream, ensuring accurate mixing ratios at each production stage and maintaining consistent product quality. On beverage production lines, they are used to monitor the mixing ratios of juice, syrup, and water, ensuring uniform taste and consistency in the final product.

In the beverage industry, sanitary magnetic flow meters also play a crucial role in the filling process. Precise flow control ensures that each bottle is filled accurately, reducing waste and improving production efficiency. Moreover, the high measurement accuracy of electromagnetic flow meters helps manufacturers control costs and prevent excess use of raw materials.

Since equipment in the food and beverage industry must be cleaned frequently, the non-mechanical design of sanitary magnetic flow meters makes them ideal for CIP and SIP processes. This design not only minimizes the risk of equipment damage during cleaning but also extends the flow meter’s service life and reduces maintenance requirements.For the measurement of milk, you can make full use of the advantages of electromagnetic flow meters and avoid their disadvantages. Moreover, the conductivity of fluids such as milk is 200~300s/cm, which is much greater than the requirement of electromagnetic flowmeters for fluid conductivity greater than 10us/cm. In addition, the electromagnetic flow sensor has a simple structure, no moving parts, does not hinder the flow of fluid, has a wide measuring range, and is electromagnetic. Flow meters have been widely used in dairy and beverage processing because of their high accuracy, good stability, and not easily affected by media.
