Product Description
The antenna of radar level instrument transmits a very narrow microwave pulse which propagates at the speed of light in space. When meeting the dielectric surface to be measured, part of its energy is reflected and received by the same antenna. The time interval of transmitting and receiving pulses is proportional to the distance between antenna and dielectric surface to be measured, and therefore the distance between antenna and dielectric surface to be measured can be calculated.
