Introduction: U-tube oscillation method density meter, electronic liquid density meter is based on the principle of different oscillation frequencies when the double U-tube is filled with different media to measure the liquid density. After pumping the liquid to be tested into the resonant cylinder sensor, the single-chip microcomputer performs measurement data processing, which is fast, direct, and highly sensitive. It is composed of double tuning fork density sensor, vibrating tube circuit, temperature measurement circuit, CPU, display, constant temperature bath, liquid inlet pump and control panel. Use field: Petroleum, diesel, cleaning fluid, lubricating fluid, chemical liquid, flux, crude oil, chemical reagent, stupid, toluene, flavor and fragrance, essential oil, Density testing in alcohol and beverage industries can convert the concentration for alcohol and sulfuric acid solutions!
