Fine-Tuning the pH Value with Acids and Lyes
The water, which is taken mostly from rivers, cannot be fed untreated into the turbine circulation. It must first run through a series of filter systems, ionizers and tricklers. The pH value must also be correct to avoid chemical reactions and deposits in the pipeline systems of the high and low pressure areas. To reach the desired pH value through neutralization, soda lye (NaOH) or hydrochloric acid (HCL) is added to the water.
Level Measurement of Hydrochloric Acid with the VEGAPULS 63
Like a knight in shining armor, the completely TFM-PTFE-coated VEGAPULS 63 can withstand any aggressive substance that confronts it. Acids and lyes can do it no harm whatsoever. With flange sizes from DN 50, it fits on any storage vessel in the feed water treatment process. It doesn’t matter whether the vessel is made of synthetic material or is rubber lined. In the case when there is no opening available in plastic tanks, the sensor can even measure right through the vessel top.
Overfill Protection with the PFA-Coated VEGASWING 63
The PFA-coated VEGASWING 63 can defy any chemical attack. Its incorruptible and reproducible millimeter-exact switching point safeguards reliably against overfilling. Because the recurring test according to WHG can be carried out with a simple keystroke, the sensor also increases the profitability of the plant. Moreover, VEGASWING 63 fulfills safety requirements up to SIL 2 (with redundancy up to SIL 3).
