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.

※2) When mount on a short stand pipe, install the level meter so that the end of the antenna protrude
from the short stand pipe.
※3) The measurement range and accuracy are guaranteed only when, antenna is pointed at an angle
perpendicular to the material surface, temperature is normal (15℃),
permittivity is more than two at high pressure, and no any presence of airborne dust, vapor,
and agitated foam.
If these conditions are not satisfied, the measurement range and accuracy may differ according to
the measurement conditions.
※4) Ensure that freezing and/or condensing will not occur inside the electronic unit.
※5) Take care that water may enter and damage the equipment, if lead outlet not tighten firmly or loosen.
When the equipment operated in the presence of process gases and/or fluids, those materials may
penetrate through resin of cone antenna and damage the equipment,
specially corrosive gases such as H2S, HCl and HF.

Fig. 5. Installation for liquid and for solid
・ 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.
・ If length of stand pipe is longer than required, such that antenna end is not protruded from stand pipe,
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 × tan16°＋φ98 (Antenna diameter)
Solid ：Distance from meas. reference point × tan28°＋φ56 (Antenna diameter)
Liquid：Distance from meas. reference point × tan48°＋φ45 (Antenna diameter)

6-2. Installation precautions
・ 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
Long stand pipe
Antenna burying
Fig. 7. Installation precaution (1)
・ 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.
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.
! Important：It 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.

10-4. Echo learning of false echo
Sets mask to unwanted reflections (false echoes or noise echoes) being received from obstructions
within a tank.
Important：In most cases sets distance from level meter to unwanted reflections as echo
learning distance. If there is true echo between the level meter and the masking distance,
then echo learning distance shall be set as distance to true echo. Actual distance to mask
will be around 1m less than the entered value.

There are two reset options. Use "Measuring reset" to restart measurement without affecting
parameters. Use "Parameter reset" to reset parameters to the default settings.
Important："Parameter reset"
・ Parameter reset returns various parameters to instrument default. Please take note of
current settings before execute parameter reset.
・ It is possible to clear echo learning range and strength by using the optional PC software,
but echo learning setting described in article 10-4 does not clear even when reset is
executed.
・ There are two reset types described above, but there is menu item "Factory reset" might
be displayed. This reset type used at factory setting and user can not apply this reset.

11．Troubleshooting
If you encounter any problems, first check if they are described in this section, then execute suggested
corrective actions.
Table 3. Troubleshooting
No.
Problem
Powered ON the device, but
screen is blank
Measured level reading higher
than material level
Measured level reading lower
than material level
Check the following
・Are wiring connections correct ?
・Check whether the power is supplied to
the device?
・ Are there any obstructions between
antenna and material surface to be
measured ?
・Are there any inlet streams of material
under
measurement
within
the
radiation angle
・ Check whether the material surface
entered to the blind sector ?
Corrective actions
・Correct the wiring
・Supply power to the device
・Execute echo learning to mask
false echo from the obstacle
・Change the level meter position
・Change level meter installation
