Principle
Radar level meter is a wireless wave ranging system based on the principle of time travel. By transmitting a low-power microwave (radio wave with a frequency of 26GHz) pulse of less than 1mW through an antenna, this pulse propagates in space at the speed of light. The microwave pulse signal encounters the surface of the tested medium, and some of its energy is reflected back by the surface of the medium and received by the antenna. The time interval between the transmission and reception of microwave pulse signals is directly proportional to the distance from the antenna to the surface of the tested medium, and thus the distance from the antenna to the surface of the tested medium can be calculated.
Advantage
The dual CPU system radar level meter adopts a design system consistent with international first tier brands, greatly improving the hardware processing ability of the product, thereby improving the measurement performance, intelligence level, and product reliability of the instrument.
The instrument adopts patented equivalent sampling pulse ranging technology, which not only improves the resolution and sensitivity of the signal, but also reduces the beam emission energy, and is harmless to humans.It can be installed in various metal and non-metallic containers or pipelines, with sensitive measurement and fast refresh speed.
Not affected by pressure changes, vacuum, temperature changes, inert gases, smoke, steam, and other environmental factors, the measurement results are stable and reliable. Customization of instrument functions and sensors can be carried out based on the operational characteristics of domestic customer industries and on-site conditions.
The waveform display function is a radar specific Hart communicator. By using the radar specific Hart communicator, it is possible to directly observe the radar waveform in the central control room and perform debugging, greatly reducing the danger and labor intensity of on-site debugging.
The LCD display unit can be connected to the outside for 25 meters, forming a display operation unit next to the tank. Reduce the risk and labor intensity of daily inspection work for instruments in high-risk areas such as large tanks, high temperature, high pressure, and toxicity.
The wireless communication function radar level meter can support GPRS wireless transmission and CMesh multi hop self-organizing wireless network transmission. It is the preferred product for level measurement and integration into the Internet of Things.
RETTAR has launched a remote display operation unit based on Hart communication, which can be connected to an external 1000 meters, thus compensating for the shortcomings of traditional tank side display units in communication distance.
Unique antenna type, more suitable for harsh on-site working conditions; Suitable for high-temperature working conditions, the specially customized high-temperature extended antenna can be used at a process temperature of 1000 ℃.
The instrument LCD display debugging unit is a 128 * 64 graphics dot matrix LCD, which supports complex operations such as full Chinese menu, waveform display, and modification of false echoes. Reduce the difficulty of on-site instrument operation and maintenance workload.
