NYRD702 PTFE 1.8GHz Guided Wave Radar Level Meter 

 

The guided wave radar level meter is a level meter based on the principle of time domain reflection (TDR). The electromagnetic pulse of the radar level gauge propagates along the steel cable or probe at the speed of light. Part of the pulse of the level meter is reflected to form an echo and return to the pulse transmitter along the same path. The distance between the transmitter and the surface of the measured medium is proportional to the propagation time of the pulse during that period, and the liquid level height is calculated.

NYRD702 anticorrosive guided wave radar level meter is more suitable for the level monitoring of strong corrosive medium, such as hydrochloric acid solution, nitric acid solution, hydrobromic acid, dilute sulfuric acid and so on

Radar Level Meter Operating Principle

 

The high-frequency microwave pulse emitted by the guided wave radar propagates along the detection component (steel cable or steel rod), and when it encounters the measured medium, due to the sudden change of the dielectric constant, it causes reflection, and a part of the pulse energy is reflected back. The time interval between the transmitted pulse and the reflected pulse is proportional to the distance of the measured medium.

◎ Enter
Guided wave radar is a measuring instrument based on the principle of time travel. The radar wave runs at the speed of light, and the running time can be converted into a level signal through electronic components. The probe emits high-frequency pulses and propagates along the cable or rod probe. When the pulses meet the surface of the material, they are reflected back and received by the receiver in the instrument, and the distance signal is converted into a level signal.
The reflected pulse signal is transmitted to the electronic circuit part of the instrument along the cable or rod probe, and the microprocessor processes the signal to identify the echo generated by the microwave pulse on the surface of the material. The correct echo signal identification is completed by the pulse software, and the distance D from the material surface is proportional to the time travel T of the
pulse:
    D=C×T/2,where C is the speed of light
    Since the distance E of the empty tank is known, the material level L is:L=E-D
◎ Export
Set by entering empty tank height E (= zero point), full tank height F (= full scale) and some application parameters, the application parameters will automatically adapt the instrument to the measurement environment, corresponding to 4- 20mA output.

Radar Level Meter Installation requirements

 

Standard installation method

 

NYRD702 PTFE 1.8GHz Guided Wave Radar Level Meter  Level Transmitter 1

 

◎ It is recommended to install at 1/4 or 1/6 of the container diameter.
Note: The minimum distance from the tank wall is L0≥300mm, H0≥50mm.
◎ Keep away from the inlet and outlet.
◎ Keep clear of obstacles such as limit switches, heating coils, agitators, etc. Note: The distance between the probe and the obstacle is ≥200mm.
◎ When the container is a metal can, the radar should not touch the wall and bottom of the can in the whole range.
◎ If the bottom of the container is tapered, the radar can be installed in the center of the top of the tank.
◎ The height of the installation short pipe should be L1≤10cm.
