Working Principle Online Density Concentration Meter
It uses the sound wave frequency signal source to excite the metal tuning fork, and makes the tuning fork vibrate freely at the center frequency. This frequency has a corresponding relationship with the density of the contact liquid. Compensation can eliminate the temperature drift of the system; while the concentration can be calculated according to the relationship between the corresponding liquid density and concentration. Application industry 1.Petrochemical industry: diesel, gasoline, ethylene, etc. 2.Chemical industry: sulfuric acid, hydrochloric acid, nitric acid, chloroacetic acid, ammonia water, methanol, ethanol, brine, sodium hydroxide, freezing liquid, sodium carbonate, glycerin, hydrogen peroxide, etc. 3.Pharmaceutical industry: medicinal liquid, biological liquid, alcohol extraction, acetone, alcohol recovery, etc. 4.Food and beverage industry: sugar water, fruit juice, brewing, cream, etc. 5.Battery and electrolyte industry: sulfuric acid, lithium hydroxide, etc. 6. Environmental protection industry: desulfurization (lime slurry, gypsum slurry), denitrification (ammonia, urea), wastewater treatment mvr (acid, alkali, salt recovery), etc.parameters
