The boiler water level gauge and the boiler form a connector. When water is not flowing, the liquid level is level and remains at the same level. By observing the water level in the water level gauge, we can determine the amount of water in the boiler and add water in a timely manner. This is used to determine the water level in the boiler.

Working principle of boiler water level gauge:
The boiler water level gauge uses the principle of a connector, and the position of the water surface we see from the transparent tube outside the boiler is equal to the actual position of the water surface in the boiler. It can be seen that when the liquid in the connector is stationary, the position of the liquid level is independent of the shape and thickness of each container.
Common types of boiler water level gauges:
Common ones include two-color water level gauges, which are used to display the water level of the boiler drum on site and are the most widely used on-site water level gauges; Magnetic flip plate level gauge, vertical tube, with a magnetic float in the tube. There are many small magnetic bodies arranged on both sides of the tube. When the water level changes, the float moves up and down. Due to the magnetic pole effect, the magnetic body flips, and different colors are brushed on both sides of the magnetic body to display the water level. Electric contact level gauge, for remote transmission, with several electrodes arranged in sequence in the vertical direction. The rise and fall of the water level will cause conduction or disconnection between the electrical stages, thereby displaying the water level; Double chamber balanced container, etc.
