sleeves for power line and grounding wire
terminals.
A disconnected cable or wire from the
terminal or a loose terminal can cause
electric shock or generate heat and cause a
fire or equipment failure.
DO
■Wiring and cabling should be done
as shown in the wiring and connection
diagrams.
Wrong wiring or cabling can cause
malfunctions,overheating,sparking,or
electric shock.
DON’T
Do not wire or cable with wet hands.

1OVERVIEW
The LQ300A00****** Density Meter measures the density of a substance that flows in a tank and
through a pipe by means of a phase difference method using microwaves.
This method is little affected by the presence of contamination. It uses no moving mechanical parts or
mechanism that is often used in other measuring methods for cleaning, sampling, or defoaming. It
permits continuous measurement.
The density meter, which outputs measured density in electric current, is suitable for an application in a
process for monitoring and controlling.
1.1 Principle of Measurement
This insertion type density meter LQ300A00****** has adopted a new measuring method called
“Phase difference method by microwaves.”When microwaves go through a substance and comes out of
it, by measuring the phase lag of the waves, we get a certain physical property of the substance that is
proportional to the density.
The theory of density measurement based on the phase difference method is shown in Figure 1.1
The difference between the phase lagθ1 of the microwave received through water (density 0%) and the
phase lagθ2of the microwave received through the object substance, that is,
Δθ＝θ2 −θ1
is determined, and since the differenceΔθis in direct proportion to the density, the density of the
object substance is measured.

1.2 Features
The Insertion Type Density Meter has the following features compared to the flow-through type density
meter:
(1) Applicable to the larger size piping or tank of more than 300 mm in meter size
In this system the transmission and reception applicators (antenna) are installed at a fixed
distance in a pipe and then the pipe itself is inserted into a larger pipe or a tank thus the
installation of this density meter is not dependent on pipe size. The density meter can measure the
fluid density in a pipe or tank exceeding 300 mm in diameter.
(2) Fluid materials with its conductivity up to 15mS/cm can be measured
New applicators are developed so that the radiation power of microwaves are concentrated on the
area between the transmission and reception applicators (antenna) and its reception applicator
can prevent unwanted electromagnetic waves from outside and this made the density meter
applicable to higher conductivity fluid materials of up to 15 mS/cm. In the case of 250 mm or 300
mm pipe size, the flow-through type density meter may be difficult to measure fluid materials due
to conductivity problems but with this insertion type density meter the measurement may be
possible.
(3) Fluid materials with its density up to 50% TS can be measured
(4) Conformed to low-level radio-wave equipment
The output of microwaves is as low as 1 mW that this density meter is categorized as low-level
radio-wave equipment. Therefore the user is free to use this density meter without applying for
permission, registration, and licenses and so on to use this density meter.
Compared with the conventional method, this phase difference measurement method using microwaves,
in principle, has the following features.
(1) Not easily affected by contamination and bubbles.
This method is measuring the variation of the transmission time but not for measuring the
attenuation of the wave motion strength that has been transmitted into the measured matter.
Therefore, it is unnecessary for the window part for sending/receiving microwaves to be
transparent as the optical type.
(2)High liability and simple maintenance.
This reliability of this density meter is high because it has no moving parts like the rotary pulp
density meter does. In addition, it has no consumable parts such as bearings or pulleys and thus its
maintenance is easy.
(3) Not easily affected by the pulp material type or freeness.
Taking density measurements captivating the dielectric change following the density change in
the measured matter, the new method has the feature of not easily affected by the pulp material
type or freeness, etc.
(4) Capable of continuous measurement.
(5) Can easily change the measurement range.
(6) The operation is simple because complex processings such as density calculation and correction,
etc. are performed automatically by micro computers.
(7) Remote control is made possible by using the hand-held terminal AF100LQ3 type (optional),
which is a specialized terminal for communication.
<Supplementary Explanation>
Density meter LQ300A00****** is equipped with the display/operation consoles as
standard. Therefore, if the meter is installed on a location easy for maintenance, the
hand-held terminal is not always needed.

Hoisting the Density Meter Before Installation
Make sure to hoist the density meter using the hoisting bands.
Hoisting it with incomplete position or condition can cause a fall or damage to the density meter.
When you move or install the Insertion Type Density Meter, make sure to hoist the density meter
usingthehoistingbands.Inaddition,careshouldbetakentoputthecushioningmaterialbetweenthe
hoisting band and the converter case. If the hoisting band touches the converter case directly it may
cause a scratch on the converter front panel.
Main unit mass: approx. 20 kg
Recommended hoisting bands: made of cloth, applicable band size 25 mm
Note: This unit is heavy. To move the unit or relocate it needs a qualified operator for handling a hand
truck, crane, hoist or other. In addition, when hoisting the unit with hoisting bands, tighten the
bands so that the bands will not be loosened or slipped off.
