FAQs

What is radar level measurement? ›

In radar level measurement, microwaves are transmitted by the antenna system of the radar sensor to the measured product, reflected by the product surface, and received back by the antenna system. The time from emission to reception of the signals is proportional to the level in the vessel.

80G Radar level transmitter

Millimeter-wave radar, with a measurement accuracy of up to ±2mm, and a minimum blind area of 0.1m. The smaller antenna size satisfies the measurement of more working conditions.

This device is a non-contact radar level transmitter that uses FMCW technology. It measures distance, level and volume of powders, granulates and other solids. It is ideal for measuring the level of solids in applications with very dusty atmospheres.

Basically, Level II data contain the radar moments (reflectivity, radial ve- locity, and spectrum width) contained on a coordinate grid consistent with the particular volume coverage pattern (VCP) used for data collection. Level III data are processed products, which can be displayed as images.

Radar systems can measure the direction, altitude, range, and speed of distant objects far from the radar site. Advanced radar systems can identify the shape and type of the distant object to track its movement.

Limited Performance in Dusty Environments: Radar level transmitters may experience performance degradation in dusty or particulate-laden environments. Dust particles in the air can scatter or absorb radar signals, reducing the signal strength and accuracy of level measurements.

In a variety of industrial scenarios, accurately measuring the level of liquids is key to ensuring the stability and safety of the production process. Radar level transmitters are a popular choice for liquid level measurement due to their high accuracy and reliability.

Who makes radar level transmitters? ›

Honeywell is a leading radar-level transmitter manufacturer, providing reliable and accurate solutions for various industries and applications.

Radar level transmitters work similarly to ultrasonic sensors. The difference is that they produce electromagnetic radio microwaves instead of sound waves. Similarly, a signal is transmitted and reflected from the surface of the liquid back to the level meter, determining the level of the liquid stored in the vessel.

A microwave signal launched into the tank is reflected back from the media surface. The level is derived from the time or frequency difference between the sending and receiving of the signal. Rosemount non-contacting radar transmitters are highly accurate and reliable direct level measurement for liquids or solids.

The 80 GHz technology used in the OPTIWAVE series is the most recent and versatile radar technology for level measurement of liquids and solids. Over an identical distance, it presents a highly focused beam with a smaller diameter compared to lower frequency radars, ideal for dusty atmospheres or low reflective media.

Low Level Transportable Radar (LLTR) is a ground based rotating Active Phased Array Radar System for air space surveillance to detect and track air targets, under hostile EW operational environments. The radar is fully programmable from the local operator work station.

Radar utilises electromagnetic waves to determine an object's position. For this purpose, the equipment measures the distance and – depending on the modulation – also further object data.

Radar sensors are not impacted by changes in atmospheric conditions in the same way ultrasonic level meters. Also, the signal is less affected by turbulence on the liquid surface. Radar systems are also capable of differentiating between foam and the liquid's surface.

How does level measurement with guided wave radar (GWR) sensors work? Whether a GWR transmitter is measuring liquids or solids, a concentrated radar pulse travels from the sensor down the metallic probe (rod, cable or coaxial probe), contacts the product and returns to the sensor.

The radar level sensor is a measuring instrument based on the time travel principle. The radar wave runs at the speed of light, and the running time can be converted into a level signal by electronic components. The probe sends out high-frequency pulses and conducts them along the cable and rod probes.
