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 field 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 specified. 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 *1. The pipe mounting
bracket is applicable to vertical or horizontal pipe (JIS 50A) as shown in Figure 3.1 and 3.2.
*1: 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 fix it
again to the detector. Figure 3.1 shows installation on a vertical pipe and Figure 3.2 shows on a
horizontal pipe.
