3. INSTALLATION, PIPING AND WIRING
Model DM8 vibration type density meter consists of a density detector and a density converter. The
density detector is generally installed in fi eld and sampling piping is made to conduct measuring
liquid. The density converter is generally installed in the vicinity of the density detector. It must not
be installed in hazardous area. It can be installed in a control room, though it is far away from the
detector, receiving digital signal.
3.1 Installation of Density Detector
The density detector is shipped with a sampling unit if it is specifi ed. For the detector without the
sampling unit, user should install sampling device suitable to measuring system.
3.1.1 Mounting Density Detector
The detector (without the sampling unit) should be installed vertically (note). The pipe mounting
bracket is applicable to vertical or horizontal pipe (JIS 50A) as shown in Figure 3.1 and 3.2.
(Note) The detector should be installed vertically to keep the vibrator pipe vertical.
(1) Pipe Mounting
The pipe mounting bracket is attached to the detector to mount it on a vertical pipe. For mounting on
a horizontal pipe, remove the mounting bracket from the detector to turn it 90° and fi x it again to the
detector. Figure 3.1 shows installation on a vertical pipe and Figure 3.2 shows on a horizontal pipe.
