Density (Consistency) Meter LQ500
Introduction
The LQ500 density (consistency) meter uses
microwave phase shift technology to determine
concentrations of solids in the material to be measured
flowing through pipes. It can perform a stable and
realtime density (consistency) measurement because
this technology is not affected by flow velocity along
with fluid color, and also is not easily affected by
contaminants and low process pressure rate. As the
LQ500 has no moving parts, it is reliable and virtually
maintenance free.
Since the output of the LQ500 is theoretically linear, it
can be applied to a wide range of density (consistency)
measurement.
<Notice>
The LQ500 requires a full pipe to measure the
density (consistency). Contact Toshiba before
installation in the following cases:
<Possibility of unfilled condition>
(a) When it is installed at the discharge of a pump.
(b) When installation is horizontal, and unfilled
condition occurs inside the pipe.
(c) A process where the pipe becomes unfilled
when the operation is stopped.

Installation Precautions
(1) Install the LQ500 in an environment free from
vibration and corrosive gases and in a place
which allows easy on-site maintenance.
(2) Provide a clearance space both detector and
converter to the front, rear, and above the unit.
See Figure 5.
(3) Provide a sunshade for the detector and
converter if direct sunlight is unavoidable
when installing outdoors.
(4) The LQ500 cannot be installed in an
environment where there is a possibility that
flammable or explosive gases may leak.
(5) The LQ500 should avoid the following
environmental installations:
• Places where condensation accumulates due
to sudden temperature changes.
• Places of low or high temperature that is out
of the specification.
• Places near equipment that produces strong
electric waves or electrolytes.
• Places where flammable or explosive gas
may be generated.

Piping Precautions
(1) A vertical installation of the LQ500 is
recommended.
Avoid installing horizontally (install LQ500
vertically) in case of follow ing e nvir onmen ts.
(2) Install the LQ500 in a pipeline where the
pipe is always filled with fluid and without
bubbles or entrapped air. If these conditions
are not satisfied, the measured value varies
or may give an inaccurate reading. It is
recommended that the LQ500 is installed at
the outlet instead of the suction side.
(3) Avoid places where sediment collects at the
bottom of the pipe.
(4) Avoid places where air gets into the fluid. To
avoid this problem, install the LQ500 to the
outlet of a pump, not to the suction side.
(5) When installing the detector horizontally,
install it so that the RF-part of it is oriented up
(that is, a pair of applicators stay horizontally)
600 (23.6”)
to make it easier for maintenance work and to
obtain its specified performance.
(6) The LQ500 can be installed in either direction
(upstream or downstream) and without
requiring a straight pipe section. Install it in a
place allowing easy on-site maintenance.

a) Places where bubbles or environments

b) Places where solids concentration in
the fluid is not even because solids in
the fluid stay either at the bottom or
top of the pipe due to slow fluid
velocity or other reason.
c) Pipe size is enlarged to install a larger
meter sized LQ500.

LQ500
V
(7) Install an adjustable piping mechanism if there
is a possibility that the detector pipe may not fit
between mating flanges.
(8) Install the LQ500 in a place where enough
water pressure is applied. Therefore, it is
recommended that the LQ500 be installed as
far away as possible from the pipe outlet
opened to atmosphere. This is to prevent the
effects of air being trapped in the liquid.
(9) If there is a possibility of no liquid flow or
uneven liquid distribution occurring when a
pump is off, use an external synch control
signal to operate the LQ500 only when the
pump is working.
(10) Provide a stop valve at upstream and
downstream of the detector, and between stop
valves and the LQ500 provide the four valves
described below with a stop valve attached to
each: 1) sampling outlet valve; 2) zero point
water inlet valve; 3) vent valve; and 4) drain
valve. If it is not possible to stop the fluid at the
point where the LQ500 is installed, provide a
bypass pipe with a stop valve provided in the
middle. These valves are needed to drain the
fluid from the detector
pipe and fill it with
drinking water (density or consistency 0%) to
adjust the zero point. See Figures 6 and 7.
(11) Use gaskets for piping of the size conformed to
flange rating and of the material appropriate
for the liquid to be measured.
Install this valve to the side of the pipe in the
case of horizontal installation. It is
recommended that a 1-inch ball valve be
installed to the side of the pipe.

NOTE:
• Zero point water valve:
Used to supply drinking water (density or
consistency 0%) to the detector pipe for zero
point adjustment. Install this valve at the top of
the pipe in the case of horizontal installation. It
is recommended that a 1-inch ball valve be
installed on the top of the pipe and zero point
water supplied through this inlet using a vinyl
hose etc.
Note: If valve water pipe is connected to this
valve, air cannot be extracted. Therefore,
another valve (vent valve) is needed to
extract air.
• Vent valve:
Used to vent process fluids to open air when
performing zero adjustment. This helps the
drinking water (density or consistency 0%)
enter the detector pipe easily. Install this valve
on the top of the pipe in the case of horizontal
installation.
• Drain valve:
Used to drain the fluids before supplying
drinking water (density or consistency 0%) to
the detector pipe for zero adjustment. Install
this valve at the lowest point of the pipe. It is
recommended that a 1-inch ball valve be
installed at the lowest point of the pipe.
• Sampling valve:
Used to extract fluids for manual analysis.

Wiring Precautions
(1) Provide a switch and a fuse to isolate the unit
from the mains power for ease of maintenance.
(2) Ground the LQ500 with 100 ohm or less
ground resistance. Do not use a common
ground shared by other power equipment.
(3) Use the accessorious cables for communication
and power supply between detector and
converter. Connect cables to the terminals that
match the marking on the cables.
(4) Use a sheathed cable with 2mm
2
cross-sectional area for AC power cable.
(5) The cables should be free from vibration and
should have no slack in the cables.
(6) Wire the LQ500 output in conduit separated
from those of AC power cable, control signals,
alarm signal or other cables which could
become the source of noise.
(7) Use a 2-wire shielded sheathed cable to wire
the LQ500 output (4-20mAdc) and
conductivity signal. Ground the shielded cable
on the receiving instrument side for both cable.

(8) As the cable port is made air-tight using a
packing, tighten the cable gland securely when
all the wiring is completed. If the diameter of
the cable is smaller than the inside diameter of
the packing, enlarge the cable diameter to the
same size as the packing by wrapping valves
around the cable Its suitable diameter is 11mm.
Tighten the terminal screws securely. Its
suitable torque is 1.0 to 1.7 N⋅m.
(9) Screws at the terminals are needed to tighten
with 1.2 N·m torque (1.4 N·m is maximum).
(10) Do not turn on the power supply under the
uninstalled condition.
(11) Each cable in the communication cable and
power supply cable between detector and
converter has a banded marks for each
terminals. Connect them correctly without any
mismatches.
•Wiring when communications function is used
By connecting the cable lead of the optional
AF900 hand-held terminal to the density
(consistency) measurement output, you can
operate the LQ500 from remote places.
1) Make sure the load resistance of 4-20mAdc
line of output is between 240 and 750 ohm,
and the load capacitance is 0.25µF maximum.
2) The AF900’s cable lead can be connected to
the LQ500 anywhere along the current output
line. For example, the cable lead may be
connected to the signal terminals on the
receiving side in the control room. See Figure
