Online differential pressure density meter uses a special density sensor to measure the density of various liquids or liquid mixtures online, directly reads the density value and outputs a 4-20mA DC signal with HART communication protocol. It is widely used in the density measurement of general liquids and in the petrochemical industry for oil, oil refining, oil blending, and oil-water interface detection; sanitary density meters can be used in the food industry for various edible liquids and soft drink processing and other production sites; anti-corrosion density meters can be used for the measurement of acid and alkali solutions and the measurement of urea, detergents, ethylene glycol, acid and alkali, and polymer density in the chemical industry. There are also many special specifications such as high temperature and horizontal pipe for high temperature working conditions of 100℃~150℃ and on-site environment.
