Method for measuring density of desulfurized limestone slurry in thermal power plant

The invention discloses a method for measuring density of desulfurized limestone slurry in a thermal power plant, which comprises the following steps of 1, model selection and installation: selecting two diaphragm pressure transmitters to replace a traditional densimeter and a traditional pipeline differential pressure transmitter, and installing the diaphragm pressure transmitters on the inner wall of a desulfurizing tower with the height difference between the two of h, 2, data monitoring: enabling the pressure transmitters to be in signal connection with a DCS through a network, and enabling the DCS to be used for processing and displaying measurement values of the two diaphragm pressure transmitters, 3, reading and calculating data, namely reading a pressure value displayed by an operation panel of the DCS, and subtracting two formulas according to a calculation formula to calculate the slurry density of limestone, and 4, comparing multiple groups of data, and averaging. The method for measuring the densi
