Feedwater

Feedwater treatment

The water, which is usually taken from rivers, cannot be fed untreated into the steam turbine loop. It has to be purified through a series of filtering systems, ionizers and degasers. The pH value of the water must also be correct to avoid chemical reactions and deposits in the pipeline systems. To this end sodium hydroxide (NaOH) or hydrochloric acid (HCL) is added to the water for neutralization. The reliable level measurement and level detection in the tanks ensures high availability of the feedwater.

Level measurement of hydrochloric acid with VEGAPULS 63

In applications with aggressive substances, VEGAPULS 63 is protected from the medium by a surface of PTFE. Thus, acids and alkalis cannot harm it. With flange sizes from DN 50, the instrument fits on any rubberized or plastic storage container in the water treatment system. In the case of plastic containers, VEGAPULS 63 can also measure right through the container ceiling.

Overfill protection with PFA coated VEGASWING 63

The PFA coating of VEGASWING 63 allows it to fend off any chemical attack. Its millimetre-exact, reproducible switching point provides security and protects against overfilling. Moreover, the recurring check according to WHG (Water Resources Act) that can be carried out by a simple keystroke on the instrument increases the profitability of the system.
