The torque should be applied in 3 steps:

step 1 : 50% of max. torque
step 2 : 80% of max. torque
step 3 : 100% of max. torque
Do not exceed maximum torque!

The torques in table 3.3.4 are designed for high operating temperature at 130°C. Installation should nevertheless always be
executed at ambient temperatures, i.e. T< 40°C. Installation at very low ambient temperatures, e.g. less than 5°C, can
possible increase the torques by up to 20%. The same also applies when the flow tubes are stored improperly, i.e. without
factory installed liner protection rings, over a longer period of time. In case that a hydrostatic test before commissioning of
the piping system reveals a leakage, a retorque should be realized in defined steps of 10% of the initial torques in the above
described way, until tightness is reached. When 100% of the initial torque is reached, a mechanical damage of the PTFE liner
is probable.

(1) Excitation Coil Check (Remote Flowtube

Check that there is continuity between terminals

continuity, the coils may be broken and replacement
or repair of the flowtube is necessary. The coil
resistance is designed to be 150 Ω or less. If it is
not, this may be an abnormal condition. Consult
Yokogawa’s sales or service offices.

(2) Insulation Resistance Check (Remote

Check the insulation resistances in the terminal
box in accordance with the tables below. If any
of them falls below the values listed in the tables,
consult Yokogawa’s sales or service offices for
investigation. If the insulation resistance cannot be
restored, replacement or repair of the flowtube is
needed. In case of submersible type flowmeters,

Metal Hat Grounding Rings /MH Metal hat grounding rings SS316 Ti (SS 1.4571) on the inlet and outlet side of the
flowtube to prevent the lining from instant abrasion. For use with abrasive media.
For use with PTFE, Linatex or soft rubber lining.
(option /E01 is selectable for receiving material certificates).
The metal head earth ring will have the dimensions of a raised face flange facing
(see page 22 to 27)
Flat Face Flanges /FF Flat face flange facing according to ASME B16.5 for DN015 to DN600 and ASME
B16.47 (chapter 6.1.3) for DN700 to DN1200.
For DIN EN1092-1 flanges, the flat face flange will be manufactured according
EN1092-1 flange facing form A.
Not available with AWWA flanges.
Not available with PTFE lining.
Wooden protection plates /WOS For PTFE lining recommended, in case media measured is corrosive to SS 1.4571.

CAUTIONS FOR INSTALLATION OF Upon delivery from the factory the PTFE lined flowtube:
• Has mounted ss liner protection rings (material 1.4571)
RXF FLOWTUBE WITH PTFE LINING on the flange facing to keep the PTFE liner at the flange
faces in place. The liner protection rings are meant to
If lining is PTFE ( lining code -T) and fluid temperature is be dismounted before installing the flowtube. However,
above 80 °C, it is required to minimize or avoid fluid if the 1.4571 material of the rings is resistant to your
permeation. Fluid permeation is mainly caused if process medium, you keep them mounted and install
significant temperature differences inside and outside the the flowtube with liner protection rings. But notice, lay
flowmeter occur. (dT > 60 °C). length with liner protection rings will be
So if your media temperature is higher than 80°C, please L = L standard + 6 mm for RXF065 to RXF150
provide insulation for the flowmeter. L = L standard + 10 mm for RXF200 to RXF600
If insulation is provided, temperature inside and outside of • Has no liner protection rings but wooden protection
the flowtube is more or less equalized, and therefore fluid plates in case of option /WOS is ordered.
permeation minimized. • Has mounted SS vent hole strainers to the vent hole
welding boss if option code /H is ordered.
• If media temperature is > 80°C insulation must surround
the meter. Therefore please exchange ss vent hole
strainers against ss vent hose connector for 6mm flex
tube. Connect vent hose prior to insulation. Both vent
hoses must penetrate the outer insulation cover in
order to allow that permeated gas / fluid can escape
to the ambient atmosphere. Vent hose connectors and
vent hose for temp < 150°C is provided with the meter if
option code/H was ordered.

Notes: (*1) Definition according PED regulation article 3, section 1.3(a) for “gas” and section 1.3(b) for “liquid”
Article 3, section 1.3(a): “gases, liquefied gases, gases dissolved under pressure, vapors and also those liquids
whose vapor pressure at the maximum allowable temperature is greater than 0.5 bar above normal atmospheric
pressure, (1013 mbar)”.
Article 3, section 1.3(a): “liquids having a vapor pressure at the maximum allowable temperature of not more than
0.5 bar above normal atmospheric pressure (1013 mbar)”.
(*2) Mentioned PS is max. value for the corresponding instrument´s size. The max. allowed process pressure of the
individual instrument might be lower, based on detailed model code (e.g. process connection or lining material)
(*3) SEP = sound engineering practice according article 3 section 3
(*4) Classification for gas per diagram 7 is only applicable for RXF[ ] with PTFE liner.

(3) Operation

WARNING

• The instrument should be operated with the

temperature and pressure of the fluid under
normal operating conditions.
• The ambient temperature should be that of
normal operating conditions.
• Take measures to prevent excessive pressure
such as water hammer, etc. To avoid water
hammer prevent the pressure from exceeding
the PS (maximum allowable pressure) by setting
the system’s safety valves, etc. appropriately.
• Should external fire occur, take safety measures
at the device itself or system-wide prevent it
having an effect on the flowmeters.
• Avoid using fluids exceeding the corrosion proof
limitations of the lining and electrodes.
• Take measures not to abrade the metal pipe,
and avoid abrading the lining by using fluids
such as slurry and sand are contained.
• The operator is responsible that no corrosion
and/or erosion is caused by the medium, which
reduces the safety of the unit as pressure
vessel. Corrosion and erosion can make the
unit fail and can lead to the endangering of
persons and facilities. If corrosion and erosion
are possible, the integrity of the tubes has to be
checked periodically.
