SS304 Radar Level Transmitter 24VDC Tank Radar Water Level Sensor

NYRD803 Stainless Steel Housing Intelligent Radar Level Meter Level Transmitter

NYRD803 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.

Radar Level Meter Technical Parameter

※ Note: Products can be customized according to the specific requirements of users!

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

◎ NYRD803 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 description

Recommended distance(1)from wall to the outer wall of installed short pipe:

• A distance from the tank wall:1/6 of the tank diameter, min. distance is 200mm
• Not allowed to install above the material feeding silo(4)
• Not allowed to install in the central position(3),in case it is installed in the center, it will cause ma false wave echo,it interrupts wave echo and cause signal loss.
• If the distance between the gauge and wall of the tank cannot be secured, the mediums on tank wall will be adhered causing false wave echo, during the gauge debugging, the false wave echo has not be saved.

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.
