What is the flow rate?

In metering technology, flow rate refers to the amount of dispensed material or liquid that exits a dispensing nozzle, valve, or device per unit of time. This term is critical to describe and control the precision and accuracy of the dispensing process.

How is the flow rate being measured?

In dispensing technology, the flow rate is often measured in units such as milliliters per second (ml/s) or liters per minute (L/min).

Why is it important to accurately measure the flow rate?

With an accurate measurement, it is ensured that the correct amount of material to be dispensed is delivered in a process or application. Accurate control of the discharge rate is especially important in industries such as pharmaceutical production, food processing, chemical, automotive, etc. - wherever accurate metering is critical to the quality and safety of the end products.

How can you measure the exact flow rate?

To control and monitor the flow rate in metering technology, dosing pumps, flow meters and other precision instruments are often used. These make it possible to precisely set the desired dosing quantities and ensure that they remain constant during the dosing process.

In which markets and industries is the flow rate relevant?

Flow rate is highly relevant in a variety of dispensing markets and industries, especially those where precise dispensing of liquids or other materials is critical.

  • Medical technology: In the manufacture of medical products such as dialysis filters or artificial lungs, accurate metering is critical to ensure quality and functionality.
  • Automotive industry: In automotive production, metering technology is used to apply adhesives, sealants and lubricants to components. Here, accurate metering is essential to meet high process control standards and ensure vehicle quality and safety.
  • Electronics manufacturing: Dispensing technology plays an important role in the manufacture of electronic components to control soldering and bonding processes and to ensure the precision of connections or to protect sensitive components from dirt, dust and moisture.
  • Aerospace industry: Dispensing systems are used in the aerospace industry to manufacture composites components or to apply adhesives and sealants in aircraft production.

Accurate control of the flow rate is a critical factor for product quality, process efficiency and safety. Therefore, dispensing systems and technologies that can precisely control the outflow rate are of great importance.
