In modern industrial production, level measurement is a crucial task. Whether it is petroleum, chemical, food, pharmaceutical and other industries, or water treatment, environmental protection and other fields, accurate measurement of liquid level is indispensable. The radar guided wave level gauge is such an efficient tool that can accurately measure the liquid level. This article will introduce the principle, characteristics and application fields of radar guided wave level gauge in detail.
First, the principle of radar guided wave level gauge.
Radar guided wave level gauge is an instrument that uses the characteristics of electromagnetic waves propagating in the medium, and calculates the time difference of electromagnetic waves propagating in the medium by transmitting and receiving electromagnetic waves, so as to determine the liquid level height. Its working principle mainly includes the following steps:
Emission of electromagnetic waves: Radar guided wave level gauges emit high-frequency electromagnetic waves through antennas.
Electromagnetic waves propagate in a medium: The emitted electromagnetic waves propagate in a liquid or solid medium, and when they encounter an interface, some of the electromagnetic waves are reflected back.
Receiving Reflected Waves: The receiver of the radar guided wave level gauge receives the reflected electromagnetic waves.
Calculate the time difference: By comparing the time difference between the emitted and received electromagnetic waves, the distance traveled by the electromagnetic waves in the medium can be calculated, and thus the height of the liquid level can be determined.
Second, the characteristics of radar guided wave level gauge.
High precision: The measurement accuracy of the radar guided wave level gauge is high, and the error range is usually within 1mm.
Non-contact measurement: The radar guided wave level gauge uses non-contact measurement and does not have any impact on the measured medium.
Wide-range measurement: Radar guided wave level gauges can measure liquid level heights from a few meters to tens of meters.
Corrosion-resistant: The probe part of a radar guided wave level gauge is usually made of corrosion-resistant materials and can be used for a long time in corrosive environments.
Easy to install and maintain: Radar guided level gauges are very simple to install and maintain, and do not require specialized personnel to operate.
3. Application field of radar guided wave level gauge.
Radar guided level gauges are widely used in a variety of applications that require accurate level measurement, such as:
Petroleum and chemical industry: used to measure the liquid level in storage tanks, pipelines and other containers.
Food and pharmaceutical industry: used to measure the liquid level in fermenters, reactors and other equipment.
Water treatment and environmental protection field: It is used to measure the liquid level in pools, water towers and other facilities.
Power industry: used to measure liquid levels in boilers, cooling towers, etc.
In summary, the radar guided wave level gauge has become an indispensable measuring tool in modern industrial production due to its high precision, non-contact measurement, wide range measurement, corrosion resistance and easy installation and maintenance. No matter what industry you are in, as long as it comes to accurate level measurement, radar guided wave level gauge can play its powerful role and provide accurate and reliable data support for production.
