Operating Principle of Non-Contacting Radar Level Sensor/Gauges (Unguided Wave)---Part three

Accuracy Level of Radar InstrumentsThe achievable accuracy of any radar level measurement system depends heavily on the type of application, the antenna design, mechanical installation, the state and quality of the electronics and echo processing softwave employed. Even though the effects of temperature and pressure variations are very small, compensation methods are still being used for these parameters. Other influences on accuracy of radar level instrument include to noise radio and interference.Areas of ApplicationRadar level instruments are widely used to measure the level of liquid, slur...

Electromagnetic flow meter --Part one

1. 1 Description of products Electromagnetic flow meter is a kind of inductional instrument designed by Faradays' law of electromagnetic induction to measure flow of conductive media in the tube. It adopts the technology of insertion of single chip to realize digital excitation and employs CAN local fieldbus. Electromagnetic flow meter can realize local indication and output electrical current signal of 4-20mA which can be used to record, adjust and control. Electromagnetic flow meters are widely used in industrial sectors such as chemical industry, environmental protection, metallur...

Operating Principle of Non-Contacting Radar Level Sensor/Gauges (Unguided Wave)---Part one

Radar level instruments measure the distance from the transmitter/sensor (located at some high point)to the surface of a process material located further below in much the same way as ultrasonic level sensor, by measuring the time-of -flight of a traveling wave and then determine the level of the process material. They are regarded as continuous level measurement devices because they continue to measure level even as the level of the liquid in the vessel changes.The fundamental difference between a radar level instrument and an ultrasonic level instruments is the type of wave used. Radar level...

Operating Principle of Non-Contacting Radar Level Sensor/Gauges (Unguided Wave)---Part two

Operating Principle of Non-Contact Radar Level SensorTo measure the level of a liquid or solid in this type of radar instrument, radar signals are transmitted from the antenna of a radar instrument located at the top of the tank or vessel as shown below:Non-contact level measurement using radar has two main modulation techniques: pulse radar and FMCW(Frequency Modulate Continuous Wave) radar techniques.In the pulse radar technique, pulse radar sent out a microwave signal that bounces off the product surface and returns to the gauge. The transmitter measures the time delay between the transmitt...
