Level measurement is an indispensable part of many industrial processes, especially in applications such as storage tanks, containers, boilers, and pumping stations. Accurate level measurement is crucial for operational safety, efficiency, and reliability. A level gauge is a device that measures the height (level) of a liquid or solid material using physical principles. Common types include float level gauges, radar level gauges, and ultrasonic level gauges. The choice of level gauge depends on the properties of the medium, the requirements of the working environment, and the required measurement accuracy.
A level switch is a device that outputs a signal when the liquid level reaches a preset value. It is typically used in level control systems. When the liquid level reaches a certain set point, the level switch triggers an action, thereby achieving automatic control of the equipment. This type of device is widely used in water level monitoring, pump control, and other fields.
A level transmitter is a device that converts changes in liquid level into a standard electrical signal (e.g., 4-20mA) for transmission. It features high accuracy and strong anti-interference capabilities and is commonly found in large-scale storage systems such as liquid and solid silos, containers, and tanks. Through level transmitters, users can monitor and adjust liquid levels in real time, preventing overflows and shortages, thereby improving automation control and production safety.
