1 1. Overview Microwave level meter measures level of bulk solids and liquids in the storage vessels without physical contact to measuring material. This model of level meter doesn't need separate output unit, which 4..20mA current output signal is carried by same two wires for power supply. 2. Measurement principle The level meter transmits microwaves at constant intervals, and receives echoes (reflection of transmitted waves) from the surface of material under measurement. The time difference between transmission and reception of microwave is processed by microcomputer to accurately determine level of stored materials. 3.

Installation 6-1. Installation If material surface enter to the blind sector, a stand pipe shall be used to ensure that material surface can not reach the blind sector of the level meter. But if the material surface will not enter the blind sector, then stand pipe should not be used. Fig. 5. Installation for liquid and for solid Blind sector 0.5m Blind sector 0.3m If length of stand pipe is longer than required, such that antenna end is not protruded from stand pipe, 0 1 5 2 45 98 then it causes malfunction of instrument. When required stand pipe length is longer than antenna, please use cone shape stand and ensure radiation angle including the side beam. Keep radiation free of interference from the stand pipe. Recommended height of stand pipe Solid: The end of the horn antenna must be protruded a minimum of 10mm from the stand pipe. Liquid: The end of the antenna must be protruded a minimum of 25mm from the stand pipe. Calculation of radiation angle expansion Solid Distance from meas. reference point tan1698 (Antenna diameter) Solid Distance from meas. reference point tan2856 (Antenna diameter) LiquidDistance from meas. reference point tan4845 (Antenna diameter) 100Radiation angle 50Side beam 8 6-2. Installation precautions Fig. 6. Radiation angle and side beam reference Set the value of 100%(20mA) level so that the blind sector is secured. Setting the 100%(20mA) level within the blind sector will cause a malfunction of the instrument. Avoid too long stand pipe to prevent malfunction of the instrument. Blind sector Fig. 7. Installation precaution (1) Antenna burying Long stand pipe Do not install instrument close to inlet of material under measurement. Do not install any interfering instruments within the side beam, because reflections from beams, pipes, and other supports within the tank will cause false echoes. Fig. 8. Installation precaution (2) Provide shielding to minimize noise or unwanted reflections, when crossbeams, and other supports are installed within the tank. 9 Fig. 9. Installation precaution (3) False reflections In environments where interfering signals are generated, level meter may indicate incorrect measurements results. False reflections up to a certain level of strength can be suppressed by executing the echo learning function. However, the level meter's installed position must be changed if true echoes cannot be received or if the reflection level (measured in dB) is extremely low. When there are obstructions such as crossbeams, pipes, or level switches in the tank, install the level meter in a position where there is no obstruction within its radiation angle. ImportantIt is not possible to specify the range of false reflections in dB that can be
!
suppressed by the learning function because the level of true echo from the surface of material differs depending on the level meter installation conditions and measuring material type. The general guideline for the level of false reflections that can be suppressed by the learning function is one third (1/3) of true echo level. Install protection such as a simple roof above the Level Meter to avoid exposure to direct sunlight. Simple cover Fig. 10. Installation precaution (4) 10 7. Wiring 7-1. Unscrew the cover. (Rotate counterclockwise) 7-2. If an optional LCD adj. unit is attached, remove it.

(0 over) SRAM failure EEPROM failure MIC unit failure Trigger signal lost LCD adj. unit failure Charge circuit failure Communication between level meter and LCD adj. unit failed No response from level meter Communication between level meter and LCD adj. unit failed Reflection echo is currently being detected There is no reflection echo There is no reflection echo in the measurement span Measured distance is lower than
"Min. meas. limit"
Measured distance is higher than
"Max. meas. limit". Measured distance exceeds "Upper range limit over (100% over)". Measured
"Lower range limit over (0% over)". undergoes distance Turn off device power and turn on again Ensure LCD adj. unit attached properly Turn off device power and turn on again Ensure LCD adj. unit attached properly Check whether there are adhesives in the horn antenna. If there is adhesives, clean the horn antenna Optimize measurement span Check setting for Min. and Max.meas. limit over, and Upper and Lower range limit over. If you set invalid then error message must be clear. Please note that those settings can be altered by optional PC software only. You can not change by LCD adj. unit 14 E0001 Error message No.11 to 14 will be displayed, only when appropriate settings are set to "Valid" by PC adjustment software Matsushima DTM. The default settings are "Invalid". If problem persists, please contact your local Matsushima sales office. Table 5. Periodic inspection Item Check of No. 1 Confirm whether there is damage on housing etc. Descriptions Interval (standard) Every 12 months 20 appearance Tighten the cover and lead outlet Tighten the bolt for installation fixture 2 Check of antenna Clean the antenna (Solid: InsideLiquid: Outside) Every 6 to 12 months Important: Standard periodic inspection interval differs depending on measurement condition and measuring material.
