Low Volume – variable area – with glass tube
Type: K09, K12, K17
Measure low volume accurate and safe
The KDS and BGK flowmeters are used for measuring the flow of liquid and gaseous products in pipes. They show the current flow quantity 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

Details
Applications
Measuring the volume flow rate of extremely low flow rates of liquids and gases
