The non-contact measurement technology of radar water level gauge has not been used for long. Abroad, the radar phase meter was used for liquid level measurement for the first time in 1975 by the Swedish SAAB . Until the mid-1990s, practical applications were rare. In China, in the 21st century, radar water level detection technology has gradually begun to be used. It is precisely because the use time is not long, so most people do not know much about the radar water level gauge. So what are the advantages and uses of radar level gauges?1. The advantages of radar level gaugeThe radar water level gauge (also known as the radar water level gauge) is a non-contact sensor that mainly works by detecting the information reflected by the microwaves released by itself to the liquid surface and converting the position of the object.In other words, if the antenna of the radar water level gauge emits electromagnetic waves, the electromagnetic waves will be reflected on the liquid surface and received by the antenna. The electromagnetic wave is proportional to the time from emission to reception and the distance from the face of the ticket. Based on the principle of time spreading technology, the time interval between the transmitted pulse and the received pulse is calculated, and the distance from the antenna to the surface of the test medium is further estimated.From this principle of the radar water level gauge, it can be seen that the main advantages of the radar water level gauge are speed, non-contact, all-weather real-time continuous detection.Due to these advantages of the radar water level gauge, it is not affected by factors such as temperature, humidity, fog, mud, sludge, aquatic plants, etc. It has the characteristics of high measurement accuracy, simple installation and easy maintenance, and it is more and more widely used.Second, the use of radar level gaugeRadar water level gauges have a wide range of uses. The application of hydrological monitoring stations, reservoirs, and urban inundation monitoring and early warning systems is relatively common. Real-time monitoring of bridges, culverts, drainage pipes, waterways, lowland roads, underground parking lots, urban rivers and lakes, etc.
Radar water level gauges can obtain accurate real-time data in a timely, accurate and scientific manner, provide reliable guarantee for decision-making, emergency and early warning, and ensure the safety of urban buildings and citizens’ lives and property under heavy rain conditions.
