Introduction
Ultrasonic level meter is a digital level meter controlled by a microprocessor. It uses ultrasonic technology to measure the distance between the surface of liquid or solid material and the sensor, so as to determine the height of the liquid level or material level.
In addition, it is widely used in industrial production, water treatment, environmental protection, food and beverage, warehousing and logistics, etc. For example, in the chemical industry, it can be used to measure the liquid level of various chemical raw materials; in sewage treatment plants, it can be used to monitor the water level of sewage pools; in the food processing industry, it can be used to measure the liquid level of food raw materials in storage tanks, etc.
