3.2 Installation Location
[NOTE]
◆ Determine an indoor installation place in accordance with the following instructions.
(1) Choose a place that is free of vibrations and corrosive gasses, and has ample space for
maintenance.
(2) Secure maintenance space in front, rear and above the density meter. (Refer to fig. 3.2.11)
(3) In the case of outdoor installation, provide covering against sun .
(4) Do not install the meter in a place where there is a possibility of leakage of flammable or
explosive gas.
(5) Do not install the meter in any of the following places:
• A place where condensation due to a sudden temperature change occurs.
• A place where extreme low or high temperatures occur outside the specification range.
• A place near the equipment generating strong radio waves or electric fields.
(6) Make sure the upstream and downstream pipes have enough strength to hold the density
meter. If it is not possible, provide a supporting base to hold the density meter.
(7) Install the meter in a place where density distribution is uniform. If the distribution inside the
pipe is uneven, manual analysis data and the indicated value of the density meter may not
show the same value.
(8) Install the meter in a place where air bubbles are not generated, inside the pipe is always
filled, and sedimentation and accumulation of solid matters do not occur.
(9) The liquid contacting materials of this meter are stainless steel SCS14A(equivalent to
316SS) and polysulfone. Install the meter in a place where measuring liquid or environment
does not corrode these materials.
(10) If the cover of the density meter is removed or the density meter is disassembled while the
meter is powered, radio waves will leak out. (However, the amount is about equal toPHS
and one tenth of mobile phones.)
