Product Description
A radar liquid level sensor is an instrument for measuring the height of a liquid and converting it to an electrical signal, it is for continuous, non-contact level measurement of liquids or solids. Radar liquid level sensors are measurement devices which transmit and receive high frequency radio waves (microwaves) to measure the distance to the surface of a liquid based substance. Radar liquid level sensors are typically housed in a single assembly combining the transmitter and receiver antenna in one device. The antenna system transmits a high frequency electromagnetic wave pulse typically in the microwave spectrum on the product to be measured. These are reflected by the surface of the product and captured again by the antenna system. The time taken for the microwave pulse to traverse the distance between the transmitting antenna and target surface, and back again to the receiving antenna is measured. The signal return time is proportional to the distance between the sensor and the target surface(e.g., water, grain, slurry). The distance (d) between the radar liquid level sensor and the liquid surface can be calculated by dividing the time taken (t) by two, and multiplying that by the speed of light (c), i.e. d = c ∙ t / 2. The liquid level in a tank (LT) can then be determined by subtracting distance (d) from the height of the radar level sensor (HT), i.e. LT = HT – d. The pulse through air radar liquid level sensor is the most commonly used type due to it being contactless and easier to install. The transmitted magnetic waves fan out from the sensor until they hit the surface of the liquid and are reflected back. It's more suitable than the submersible type, when the installation is made difficult due to strong current, possible overflows and edges of the unaccessible water basins. Due to high frequency electromagnetic pulse waves and precise transmitting time measurement, the data it collects are accurate in all types of environmental conditions, even for solids and low dielectric constant fluids.
What is the main difference between radar sensors and ultrasonic sensors?
Unlike ultrasonic sensors, the performance of a radar level sensor is not easily affected by temperature changes, humidity or vapour between the sensor and the liquid surface. This is because changes in air density only have a very small effect on the speed of electromagnetic waves. Also radar liquid level sensors can work in a vacuum, high pressures and high temperatures without any noticeable difference on measured transit time, so it can be used in applications where it is not possible to use ultrasonic based sensors. Due to the high frequency electromagnetic waves used, it is possible to measure distance to a very high accuracy, as long as the surface is not too close to the sensor, where the pulse transit time becomes too small to measure precisely. This is called the dead zone, blocking distance or deadband, and is typically greater than an ultrasonic based device.

CMOS chip
Based on the CMOS millimeter wave pluse chip, a more compact pluse architecture, a higher signal-to-noise ratio, a smaller blind zone, and a more stable and sensitive signal are realized. The cavity is glue-pouring sealing with high-density epoxy resin, which can prevent moisture from entering the body.

Intelligent echo analysis
The hardware system uses advanced microprocessors and embedded system processing software, the signal algorithm processing integrates advanced Echo-capture signal processing technology, this makes the product is not affected by various complicated working conditions, such as strong surface fluctuations, foam, moisture and dust interference.
Pluse type
Pulse transmission type, a time interval between the transmitted wave and the received wave to avoid the interference cased by the transmitted wave, and the transmission power is low.

10° Beam Angle
The narrow acoustic beam with 10° beam angle can keep the energy concentrated, small divergence and strong penetration ability, to realize the large measurement range, and it can also help to reduce the unwanted reflection make the measurement is more accurate.

Self cleaning of antenna (optional)
Some volatile organic matter in the measuring medium will crystallize on the horn or antenna of the radar level gauge, it will increase interference caused by buildup, proper cleaning of the antenna will fix this problem and get us back to reliable measurements
