Description
Technical Field
[0001] The utility model belongs to the technical field of density meters, in particular to an online density meter for a fluid pipeline. Background Art
[0002] An online density meter, also known as an online density transmitter, is a device used to continuously measure the concentration and density of liquids online and can be directly used in industrial production processes. By extending the detection end of the online density meter to the inner cavity of the catheter and contacting it with the fluid in the inner cavity of the catheter, the device can detect the density of the fluid and display the detected value on its own display screen. To ensure stability during use, existing density meters are installed on the fluid pipe through mounting components with multiple bolts, thereby ensuring the stability of the online density meter during use. Although this increases the stability of the device to a certain extent, multiple bolts need to be removed during maintenance and disassembly of the online density meter, making the installation and disassembly of the online density meter time-consuming and labor-intensive.
[0003] A search revealed a Chinese patent document (authorization publication number CN221056270U). This utility model discloses an online densitometer for a fluid pipeline, comprising an online densitometer body, a fixing seat threadedly connected to the periphery of the body, a connecting seat fixedly connected to the lower end of the fixing seat, a slide groove defined within the connecting seat, a spring fixedly connected to the inner wall of one side of the slide groove, a latch fixedly connected to the other end of the spring, and a connecting pipe slidably connected to one side of the latch. While this patent improves the stability of the device to a certain extent, the online densitometer requires the removal of multiple bolts during maintenance and disassembly, making installation and disassembly of the online densitometer time-consuming and labor-intensive.
