What are the 6 main indicators of water quality? Temperature, Dissolved oxygen, pH, Turbidity, Total dissolved solids (TDS), and Chemical pollutants. Learn more about the steps for water quality analysis.

An ultrasonic level sensor uses high-frequency sound waves to measure the distance from the sensor to the liquid or solid surface. The sensor sends out a sound wave that bounces off the surface and returns to the sensor. The time it takes for the sound wave to travel to the surface and back is used to calculate the level. A radar level sensor, on the other hand, uses electromagnetic waves to measure the level. The sensor emits a radar signal that travels to the surface of the liquid or solid and is reflected back to the sensor. The time it takes for the radar signal to travel to the surface and back is used to calculate the level.

A water flow meter is a flow meter that measures and displays the flow rate of water. Water flow measurement is important for industrial applications such as wastewater treatment, and food & beverage.

The electromagnetic flow meters are used in various applications, such as wastewater treatment processes, measuring the flow rate of raw sewage, effluent, and sludge.

How to classify automation instruments? According to the different measured parameters, it can be divided into pressure gauge, temperature gauge, liquid level gauge and flow gauge. What are temperature detection instrument, pressure detection instrument, flow detection instrument?

Learn the working principle of radar level sensors and guided wave radar level sensors and the difference between them. Radar level sensors and guided wave radar level sensors are used in different applications.
