5. Do not install the meter at a place where oil mist or powder of dust is
wafting.
Caution
1. Use the meter in a condition in which the generation of oil mist due to
reliquefaction can be avoided. Oil mist that adheres to inside the flow rate meter
may cause errors in flow rate measurement, hindering accurate measurement.
2. When the meter is used for a dry gas (e.g., 13A gas), the powder of dust (foreign
particles) in the pipes may cause a failure in the rotating part, hindering accurate
measurement.
6. Do not tighten the flange-stuffing nuts too strong when installing the
meter.
Do Not
Fasten all the nuts softly before tighten
them in an even, crisscross pattern
(applicable for TBX100F (D) and
TBX150F (D)).

m max*
* Secure the minimum design fastening pressure recommended by the gasket
manufacturer. Depending on the use conditions, the fastening torque may have to be
controlled at a pressure exceeding the minimum design fastening pressure.
7. When connecting the meter to a counter pipe, align the centers.
Do
Use caution not to cause an eccentricity,
inclination, or twist.
Do not apply an excessive stress loading
to the main body of the meter. (applicable
for TBX100F (D) and TBX150F (D)).
8.
When using newly installed pipes, purge the pipes for removing foreign
objects before installing the meter.
