Applications
The liquid online density meter is a portable instrument used to measure the 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.

Tips: Working principle of online liquid density meter
The instrument is mainly composed of a built-in density sensor, a temperature sensor, a signal line, an intelligent controller, etc. It measures the density and temperature of the liquid in real time through the built-in sensor probe, and transmits the collected signals to the intelligent controller through the signal line. The intelligent controller contains signal conditioning circuits, multi-channel AD conversion circuits, and CPU intelligent processing units to calculate and process the original signals, and finally convert them into readable density values, temperature values and other parameters. It also supports the storage of the latest 200 sets of measurement data for easy data tracking and analysis.
