Temperature measurement
temperature measuring range of converter :
Standard, /Lt, /Mt : -200°C to 230°C
option /Ht : 0°C to 350°C
accuracy:
Standard (-70°C to 150°C) : ±(0,5°C+0,005*abs(t
medium
-20°C))
option /Mt (-70°C to 230°C): ±(0,5°C+0,005*abs(t
medium
-20°C))
option /Lt (-200°C to 150°C): ±(1,0°C+0,008*abs(t
medium
-20°C))
option /Ht (0°C to 350°C) : ±(1,0°C+0,008*abs(t
medium
-20°C))
For process temperatures more than 80°C higher/lower
than ambient temperature the detector should be insulated
to maintain optimum accuracy.
Heat Tracing
Heating with heat carrier, insulation and protection housing.
the max. surface temperature at the protection housing
from inner heating is 40°C. above 150°C process tempera-
ture insulation from the manufacturer is recommended.
However
up to 230°C process temperature the customer can insulate
the detector themselves.
option /t1 : only insulation and protection
option /t2 : insulation, protection and heating line
option /t3 : like /t2 but with ventilation
Process connection for the heat carrier fluid (see table 10):
for D-type flanges : En Dn 15 Pn 40 Form B1
for a-type flanges : anSI ½ - 150 lbs.
for J-type flanges : JIS Dn15 10K
Max. pressure : Pn 40
Protection class : IP54, install roof protected
For fluid temperatures below -70°C select option /Lt and
ask for special insulation (see also page 10).
Calibration for liquids and gases :
the RotaMaSS flowmeters are always factory calibrated
with water. Calibration Conditions:
- Water : 22.5°C ± 12.5°C
- ambient temperature : 22.5°C ± 12.5°C
- Process Pressure : 1 to 2 bar abs
For gas applications please choose option /Ga.
all specifications are based on above mentioned calibration
reference conditions, a flow calibration protocol is attached
to each instrument.
Special calibrations
- Mass-/Volume flow calibration with factory certificate (option /K2):
Calibration with water at customer specified flow values
according calibration order sheet.
- Mass-/Volume flow calibration with DKD certificate
(En17025: 2005) (option /K5):
Calibration with water at customer specified flow values
according calibration order sheet.
- Density calibration with factory certificate (option /K6)
(not with /Ga):
adjustment and check with 3 different fluids, fluid temperature
influence adjustment for low ambient temperature influence
and thermal treatment for long term density measurement
stability, enhanced temperature measurement (see also
page 11).
dual Seal approval (option /dS):
- Conform with anSI/ISa-12.27.01.
- only for use with hazardous substances.
- up to anSI class 900 line pressure.
- only with FM approval option.
- For liquid application the leakage detection is realized by
software in the converter.
- For gas application options /Ga and /RD (rupture disk)
are mandatory.
- Rupture disk is only for annunciation.
NOrMAL OPErATING CONdITIONS
Ambient temperature limits
- Remote detector RCCS3 :
Standard
: -50°C to +80°C
option /Lt : -50°C to +80°C
option /Mt : -50°C to +80°C
option /Ht : -50°C to +65°C
(up to 280°C medium temperature)
-50°C to +55°C
(up to 350°C medium temperature)
terminal box lower 100°C
- Remote converter RCCF311 and Integral type RCCt3:
Display operating range
: -20°C to +55°C
Electronic operating range : -40°C to +55°C
Cold start : above -30°C
Where meters are mounted in direct sunlight, it is recom-
mended to install a sunshade. this is particularly important in
countries with high ambient temperatures.
Ambient humidity limits : 0 to 95% R.H.
Process temperature limits
Detector :
- RCCS30 to 33 : -50°C to 150°C
- RCCS34 to 39/XR : -70°C to 150°C
- RCCS34 to 39/XR /Mt : -70°C to 230°C
(Range 150°C – 230°C
recommended with /tx option)
- RCCS34 to 39/XR /Lt : -200°C to 150°C
- RCCS34 to 39/IR /Ht : 0°C to 350°C (only with /tx option)
For use in hazardous area -50°C is low limit.
Integral type :
- RCCt34 to 39/XR
: -50°C to 150°C
Heat carrier fluid temperature limits
(option /t2 or /t3 only for remote type RCCS30 to 39/IR)
- Standard
: 0°C to 150°C
- With option /Lt : -200°C to 150°C
- With option /Mt : 0°C to 230°C
- With option /Ht : 0°C to 350°C
For fluid temperatures below -70°C select option /Lt and ask
for special insulation (see also page 10).
Process pressure limits
according to the flange ratings:
- En Pn 16
: max. 16 bar
- En Pn 40 : max. 40 bar

the RCCS30 to RCCS34 have also thread connection. For
these connections the max. allowed tube pressure is the
limitation. For all other standard process connection please
find the max. process pressure in table 9.
