NYRD801 Radar Level Meter Stainless Steel Intelligent Low Emission

NYRD801 Intelligent Radar Level Meter 

Radar Level Meter Operating Principle

Low emission energy pulses through very short microwave transmitting and receiving antenna systems. with the speed of light. Running time can be converted to the electronic components of level signals. A special time for a very short extension method ensures stable and accurate measurements.
Even if the condition more complex cases, there is a false echo, with the latest micro-processing technology and debugging software can accurately analyze the material level echo.

Input

The antenna receives the reflected microwave pulses and transmitted to the electronic circuit, the microprocessor processes this signal, identify the micro-pulses generated in the material surface echo. Correct echo signal recognition by the intelligent software completed up to millimeter accuracy. Distance D from the material surface and the pulse travel time T is proportional to:

    D=C×T/2
Where C is the speed of light
Because the distance of the empty tank E is known, then the level L is:
    L=E-D

Output

By entering the height E (= zero) of the empty tank, full tank height F (= Full Scale) and some applications to set the parameters, application parameters will automatically adapt the instrument to measure the environment. Corresponds to the 4-20mA output.

Radar Level Meter Design Features

◎ NYRD801 of level meter is suitable for continuous non-contact measurements of liquids, Slurry and pellets, pressure variation; the presence of inert gases and volatile situations
◎ Use microwave pulse measurement method, it can be worked normally within the band of frequent industry . For the lower energy beam, can be installed on a variety of metals, non-metallic container or pipe, no harm to humans and the environment.

Radar Level Meter Installation requirements

Installation inside the tank

• Within then signal wave beam, avoid following material to be installed (1)Limit switch, temperature sensor, etc
• Symmetric position(2)vacuum ring, heating coil, apron, etc.
• If there are (1)(2)interference substances, apply guided wave tube for measurement.

Optimized installation option

• Antenna size: the bigger the antenna size is, the smaller the wave bean angle is, and the interruption wave echo will be weaker.
• Antenna adjustment: adjust antenna to the optimized measuring position.
• Guided wave tube: the guided wave tube is used to avoid interference wave echo.

NYRD801 Installation inside the tank

Standard installation:

• Antenna cannot be inclined towards tank wall.
• In order to minimize the influence of the temperature, place a spring gasket at the connection of the flanges.
• For rod type antenna, the installation short pipe must be extended outside.
• Put the rod type antenna vertically; do not let the bean point towards the tank wall.
