Intelligent Guided Wave Radar Level Transmitter For High Temperature Liquid
Working principle of Intelligent Guided Wave Radar Level Transmitter For High Temperature Liquid
When the guided wave radar level gauge transmits electromagnetic pulses, when it passes through the top of the guided wave cable, it will generate a false echo because it is close to the transmitting end, and the interference can be eliminated by filtering the false echo. When the electromagnetic pulse propagates down the waveguide, when the signal reaches the surface of the measured medium, part of the echo will be reflected, and a step change will be generated on the echo curve. Another part of the signal will continue to propagate downward until the loss is continuously transmitted. The liquid level gauge detects the time difference between the liquid level echo and the top emission echo. According to this time difference, the intelligent signal processor can calculate the height of the liquid level.
Design features of Intelligent Guided Wave Radar Level Transmitter For High Temperature Liquid
◎Guided wave radar object level meter attempts advanced microwave processing technology and unique Echo Discovery Echo processing technology, contacting measurement, highly-accurated measurement, more accurate measurement. Besides, which is guided wave radar is not affected by external environment such as medium temperature and adhesion.
◎The 70-X series guided wave radar object level meter is suitable for versatile complicated working conditions and applications due to the versprocess connection modes and detection module types. For instance: high temperature, highly-pressured and low dielectric constant medium.
◎Pulse working moder, low emission power, can be installed in a large variety of corrosive, non-metal containers and non stainless steel no harshness to human body and the surroundings around.
