10 Instructions for installation and piping work
1. This turbine meter is designed for indoor installation. Install it at a place that is not splashed
with rainwater.
2. This turbine meter can be used with both horizontal pipes and vertical pipes. Install it in the
middle of a straight pipe section.
3. Do not install this turbine meter at a place where liquid such as oil or water may accumulate.
4. Install a strainer (200 mesh) upstream from this turbine meter (see page 3).
5. Do not install this turbine meter at a place where oil mist or powder of dust is wafting. It may
cause a failure in the rotating part, hindering accurate measurement (see page 4).
6. Do not install this turbine meter to equipment that generates pulsatory motion, such as a
gas engine. The measurement will be inaccurate.
7. Straight pipes having a length of 10D (i.e. 10 times the pipe diameter) or greater must be
provided prior and subsequent to this turbine meter.
8. Use caution not to let foreign objects such as weld tips, foreign objects, and sealant enter
during the installation of pipes.
9. Do not install this turbine meter at a place where it is subjected to an impact pressure.
10. Place noise sources, such as a control device of electromagnetic valves and power lines,
one to two meters away from the meter main body and the external connection cable.
11. The direction of the indicator against the pipes is selectable.
12. Connect a 12 to 24 VDC power source when this turbine meter is the external power source
type. On that occasion, use caution not to make a short circuit. The power source used
should be an isolation type having a short-circuit protection function.
(1) In case of TBX30 (D)
(1) On installation
Secure the connection unit first, and then screw pipes with tapered external threading into
both ends of the meter.
(2) On maintenance
1.
Remove the bolts (8 pcs.) located outside of the connection unit, and then you can
take out the body perpendicular to the pipes.
2.
Replace the O ring with a new one, apply grease on it, and insert the meter to the
pipes.
