Density (Consistency) Meter LQ500
Introduction
The LQ500 density (%TS, 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 (%TS, 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 (%TS,
consistency) measurement.
<Notice>
The LQ500 requires a full pipe to measure the
density (%TS, consistency). If certain amount of
bubbles are obviously mixed in measuring media,
there are possibilities of causing measuring error.
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.
