Sodium Hydroxide (NaOH), Brine (NaCl), Hydrochloric Acid (HCl), Sodium Hypochlorite (NaClO)
In chemical plants, different chemicals are loaded and unloaded from trucks or rail cars to receiving or storage tanks, possibly to multiple unloading stations. Thus, fast and reliable interface detection is necessary for product identification and safe unloading operation.
Refractive index is a reliable method for identifying a chemical before unloading it into receiving tank. Vaisala K-PATENTS® Process Refractometer PR-43-G provides repeatable refractive index measurements with accuracy of nD +/-0.0002.
