Feed water quantity measurement

As part of our series of articles on ‘Boiler system components and their function’, today we are introducing a central, albeit inconspicuous, component: feed water quantity measurement.

This measurement is used to precisely record the amount of feed water supplied to the steam boiler. This continuous recording ensures that the water and steam balance of the boiler system can be reliably monitored and controlled as required. This is an essential basis for the safe, efficient and economical operation of a steam boiler system.

For this measurement, a flow meter is usually integrated directly into the feed water pipe. At Hagelschuer, we use devices that operate according to the vortex measurement principle:

• A so-called bluff body is installed in the pipeline.
• The flowing medium (feed water) forms vortices on both sides of this bluff body – the so-called Kármán vortex street.
• A sensor records the frequency of these vortices. The current volume flow is calculated from the measured vortex frequency.

The vortex measurement principle offers several advantages:

• Low maintenance and wear thanks to the absence of moving parts.
• High measurement accuracy with low susceptibility to interference.
• Long-term stability of the measurement results.

The use of this technology increases process reliability and optimises the operational management of the steam boiler system. Would you like to learn more about feed water volume measurement or do you require individual technical advice?
