Emerson flowmeters have a compact design, allowing them to be installed in tight spaces, while providing high-precision measurements of flow rate and density for various process media. It is difficult to determine the density of limestone slurry using conventional methods, and it is hard for ordinary enterprises to choose the type of limestone slurry. Using Emerson flowmeters is currently the main method for measuring slurry density. This method is accurate and reliable, and suitable for applications with a wide range of grouting densities. It can fully meet the requirements for on-site use. To make better use of Emerson flowmeters, the following aspects should be noted. 1. Do not install it directly at the outlet of the vertical exhaust pipe; it should be on the pressure side of the pump. Whether installed vertically or horizontally, the measuring tube should point upward to prevent frequency changes caused by the accumulation of solid residues from affecting the accuracy of its density measurements. 2. The high-speed flow of limestone slurry causes significant wear on the measuring tube of the mass meter, affecting its service life. Therefore, the flow rate through the mass meter should not be too high in order to extend its service life and reduce costs. If the flow rate in the main pipeline is too high, a mass meter can be installed on a bypass, with the flow rate being controlled via a valve. 3. After long-term use, due to factors such as material accumulation, wear, and corrosion, the mechanical structure of the measuring tube changes, and its resonance frequency is affected by these factors. Before long-term use, the pipes should be rinsed with clean water to prevent limestone from adhering to the walls of the measuring tubes, which could lead to blockages and a loss in measurement accuracy, or even make measurement impossible.
