Application
This online density meter for liquid is a portable device used to measure density indicators of various liquids or liquid mixtures. It has been widely used in various industries such as water treatment, petrochemicals, food processing, pharmaceuticals, dairy products, archaeology, mining, and shipping.

Working principle
The portable online density meter for liquid mainly consists of built-in density sensors, temperature sensors, signal lines, intelligent controllers, etc. It measures the density and temperature signals of the liquid through a built-in sensor probe. The signals are transmitted to the intelligent controller through a signal line, and the raw signals are processed into multiple parameters such as density and temperature values that can be read through signal conditioning circuits, multi-channel AD conversion circuits, and CPU intelligent processing units. It also remembers the most recent 200 sets of measured data.
