Measure low volume accurate and safe
The K09 flow meter is suitable for flow measurement of liquid or gaseous products in pipes. It shows the current flow rate in volume or mass per unit in time.
For process monitoring and regulation, the units are available with additional electrical equipment.
- A variety of sealing materials
- Wall mounting possibility
- Version c/w inlet/outlet pressure regulator (optional).
- Limit switches
Applications
Here are some aspects to consider when applying the flow meter with a glass tube in the industrial setting:
- The glass material should resist corrosion and withstand exposure to potentially corrosive chemicals commonly found in the chemical and petrochemical industry. Ensure that the glass variable area is selected based on its ability to operate within the temperature and pressure ranges present in chemical and petrochemical processes.
- In the oil and gas industry: a low-volume Variable Area Flow Meter with a glass tube is suitable for applications where precise measurement of low flow rates is essential for accurate monitoring and control of processes in the oil and gas industry.
- In the food industry: choose a flow meter specifically designed for low-flow applications. Ensure it meets the required accuracy and has a glass tube for visual inspection. Implement protective measures to prevent external contamination. This may involve using shields, covers, or enclosures to safeguard the glass tube from foreign particles.
- In pharmaceuticals: consider integrating the flow meter with control systems or data acquisition systems for real-time monitoring. Integration can enhance process control, provide valuable data, and contribute to overall efficiency and quality assurance.
