MPS7oo0 FMCWRadarLevel Transmitter

1.Introduction to Product

1.1. Measuring principle

MPS70o0FMCWRadarLevelTransmitterisaD-band( 1 2 0 { G H z } ) FM-CWradarlevel transmitter,which is suitable for continuous level measurement of various liquid and solid medium,with a maximum measuring span of 1 2 0 { m } ：

MPS7000 FMCW Radar Level Transmitteris designed with FM-CW technique.Its antenna emitsa 120 GHZ-140 GHz high frequency microwave signal of linear frequency modulation.After the signal reaches the surface of the measured medium,part will be absorbed,while the otherpartwill be reflected.The radar mixes the collected reflected signal with the transmitted signal to get a differencefrequencysignal.Thenthefrequency difference isobtainedbyFFT orDFT transformationand a series of operations.The difference is proportional to the distance from the radar antenna and the surface of the measured medium.The larger the frequency difference is, thefarther the material distance is.The distance from the measured medium to the meter flange can be calculated from equation (1).

Wherein,D is the distance from the measuring reference surface to the measured medium,C is the propagation speed of light (electromagnetic wave） in vacuum, \Delta f is the frequency difference between the received signal and the transmitted signal,and R is the change rate of the frequency of the transmitted signal with time.

Then,the level heightcan be calculated from equation (2)according to the empty material level set by the user.

4.1. Unpacking and inspection

\blacktriangle The meter is packed in a carton box or wooden box.Rudely loading or unloading is forbidden.It must be very careful with carrying and handling.The storage site should be in compliance with the conditions as follows:

\succ Rain-proof and moisture-proof; \blacktriangleright No mechanical vibration or shock; \succ Temperature range: - 1 0 ^ { \circ } { C } { ~ } 5 5 ^ { \circ } { C } ： \succ Relative moisture: no more than 8 5 % \succ No corrosive gas in the environment. \bullet Check all the items listed in the packing list,which includes meter model and quantity,accessories, operating manual etc.Incase of any mistake,lack of goods or damage,please contact thecompany or its local agent.Packing boxes are not being taken back.

4.2. Selection of installing position

Recommended mounting position as shown below.

Precautions:

\spadesuit Keep the meter farfrom the feed inlet,and avoid material flow.
\bullet Keep the meter at least 2 0 0 {mm } away from the tank wall.
\bullet For installation in conical,arched tanks,do not install the meter in the dead center.
\bullet For installation in solid tanks,try to make sure that the meter antenna is pointing at the discharge port.
\bullet For installation inagitator tanks,installthe meter at 1/2of the distance between the outer edge of the stirring blade and the tank wall as far as possible.
\spadesuit It should be installed in a place which is convenient for instalationand wiring,soas to promote future disassembly and assembly.
\spadesuit If the meter is to be installed in an explosion-proof area,national provisions on explosion-proof hazardous areas should be followed.
\bullet The meter should be kept from direct sunlight.Long-term exposure to the sunshine may cause the meter to be overheated or the plastic part aged.
\bullet There should be no blocks in the antenna microwave transmiting beam angle,so the facilities such as ladder,limit switch,heating equipment,bracket,etc.in the tank should be kept away fromas much as possible during the installation.
\bullet The maximum level of the measured material should be lower than the measuring blind zone of the meter (usually the end of the antenna,and the blind zone of low dielectric constant or solid material should be properly increased),and the distance between the end of the antenna and the surface of the medium should be at least 5 0 {mm } ,so as to prevent the antenna from being polluted by the material.

4.3. Installation requirement of liquid measurement

\bullet The meter should be installed vertically.
\blacktriangle It is advised to be installed from the openingat 1/2 of the tank radius.
\blacktriangle The smoother the standpipe end,the larger the diameter and the smaller the height,the better the use effect.

4.4.Installation requirement of solid measurement

Inmeasurementof solidandpowder,the build-upofmaterial may form a tapered surface.Therefore,the angle of the meter should be adjusted properly to achieve the best measurement effect.

Note:If MPS72OO is equipped with a purge structure,the air source pressure is recommended to be 0 . 6 \ { M P a } { ~ } 0 . 8 MPa (the pressure in the tank and the dryness of air source will affect the purging effect).By default,the air source interface has G1/8" female threads and a PC8-O1 quick connector.

4.5.Installation in tank side display unit (optional)

4.5.1.Installation in standpipe

4.5.2. Installation in guide rail

4.6.Confirmation of installation

\blacktriangle Confirm that the meter is grounded correctly;
\bullet Confirm that the meter enclosure has been screwed tightly;
\bullet Confirm that the meter measures normally and the output is consistent with the setup in the central control room;
\blacktriangle Ensure that the outlet of the meter entrance cable is tightened and the unused outlet is sealed by plugging;
\spadesuit Make sure that the instrument conduit arranged on site will not cause water accumulation to the meter;
\bullet Make sure that the cable connector of the meter complies with relevant protection standards and regulations;
\spadesuit Make sure that processconnection components,such as flange gaskets and bolts,are suitable for the field working conditions;
\blacktriangle Make sure that the process parameters of the field working conditions do not exceed the maximum process parameters allowed by the meter.

Warning:
