Contactless Tank Liquid Radar Type Level Sensor Radar Level Transmitter Specification Measurement
hot sale oem radar fuel tank level detectorl meter sensor
Radar level sensor emits a very narrow microwave pulse, the pulse to the speed of light in the space, encountered the surface of the measured medium, part of its energy is reflected back, the same antenna to receive. The time interval between the transmitting pulse and the receiving pulse is proportional to the distance from the antenna to the surface of the measured medium to calculate the distance from the antenna to the surface of the measured medium.
Radar level sensors are mounted above the liquid level on the top of the tank, or on a platform that spans the top of the open tank.

FEATURES AT A GLANCE
1.Small antenna size, easy to install
2.Non-contact radar, no wear, no pollution
3.Serious dust environment on the high level meter work has little effect.
4.A shorter wavelength, the reflection of solid surface inclination is better
5.Beam angle is small, the energy is concentrated, can enhance the ability of echo and to avoid interference.
6.The measuring range is smaller, for a measurement will yield good results.
7.High signal-to-noise ratio, the level fluctuation state can obtain better performance.
8.High frequency, measurement of solid and low dielectric constant of the best choice.
