Page 7: Applications
Heinrichs Messtechnik GmbH Applications KDS und BGK The KDS and BGK flowmeters are used for measuring the flow of liquid and gaseous products in pipes as well as dosing, monitoring, adjusting and controlling them. They show the current flow quantity in volume or mass per unit in time. -
Page 8: Operational Mode And System Design
Heinrichs Messtechnik GmbH Operational mode and system design Measuring principle for BGK and KDS-K/C/S flowmeters Float principle: The product flows through the meter vertically from the bottom to the top, lifting the float until the buoyancy force and the weight of the float establish equilibrium. The height of the float is a measure of the flow quantity. KDS-K/C/S and BGK system design The meter consists of a conical fitting pipe with a float that can move vertically. -
