The difference between a level gauge and a material level gauge

Thread Content

Level gauges and material level gauges are instruments used in industrial production to measure the level of liquids and solids, respectively. It is also an indispensable and irreplaceable on-site monitoring instrument in industrial production, as well as a remote-transmission type instrument. It is widely used in enterprises in the petroleum, chemical, smelting, pharmaceutical, food, cement, power, and other industries. Level gauges and material level gauges are sometimes also referred to as material level transmitters or liquid level transmitters. Next, a brief introduction will be given to the differences between level gauges and material level gauges. 　　 A level gauge is a sensor that continuously and in real time detects changes in the liquid level within a container. Level gauges include: magnetic float level gauges, quartz tube level gauges, insertion type level gauges, new type buoy level gauges, submersible level gauges, wire rope level gauges, capacitive level gauges, and more. The level gauge operates on the principles of buoyancy and magnetic coupling. As the liquid level in the container under measurement rises or falls, the float in the main tube of the level gauge moves up and down accordingly. The permanent magnet inside the float transmits a magnetic signal to the on-site indicator, causing the red and white flip columns or flaps to rotate 180°. When the liquid level rises, the flip columns or flaps change from white to red; when the liquid level drops, they change from red to white. The boundary between red and white on the indicator represents the actual height of the liquid level in the container, thereby enabling the indication of the liquid level. A level gauge is a sensor that continuously and in real time detects changes in the height of solid materials within a container; examples include level gauges, radio frequency capacitive level switches, radio frequency admittance level gauges, and probe-type level gauges.
