Temperature measuring range of converter :
Standard, /LT, /MT : -200°C to 230°C
/HT : 0°C to 400°C
Accuracy:
Standard (-70°C to 150°C) :
±(0.5°C+0.005*abs(T
medium
-20°C))
/MT (-70°C to 230°C) :
±(0.5°C+0.005*abs(T
medium
-20°C))
/LT (-200°C to 150°C) :
±(1.0°C+0.008*abs(T
medium
-20°C))
/HT (0°C to 400°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.
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 temperature
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 uid (see table 11-9):
for D-type anges : EN DN 15 PN 40 Form B1
for A-type anges : ANSI ½ - 150 lbs.
for J-type anges : JIS DN15 10K
Max. pressure : PN 40
Protection class : IP54, install roof protected
For uid temperatures below -70°C select option /LT and ask
for special insulation (see also page 11-5).
:
The ROTAMASS owmeters 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
- Installation: RCCS/30 to RCCS/T38 vertical
RCCS/T39 to RCCS/T39/XR horizontal
All specications are based on above mentioned calibration
reference conditions, a ow calibration protocol is attached to
each instrument.
- Mass-/Volume ow calibration with factory certicate (option /K2):
Calibration with water at customer specied ow values
according calibration order sheet.
- Mass-/Volume ow calibration with DKD certicate
(EN17025: 2005) (option /K5):
Calibration with water at customer specied ow values
according calibration order sheet.
- Density calibration with factory certicate (option /K6)
(not with /GA):
Adjustment and check with 3 different uids, uid temperature
inuence adjustment for low ambient temperature inuence
and thermal treatment for long term density measurement
stability, enhanced temperature measurement (see also
page 11-6).
- 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.
- Remote detector RCCS3 :
Standard + /LT : -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 RCCF31, RCCR31 and Integral type
RCCT3:
Display work. range : -20°C to +55°C
Electronic work. range : -40°C to +55°C
Cold start : above -30°C
Where meters are mounted in direct sunlight, it is
recommended to install a sunshade. This is particularly
important in countries with high ambient temperatures.
: 0 to 95% RH
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
(option /T2 or /T3 only for remote type RCCS30 to 39/IR)
- Standard : 0°C to 150°C
- With option /MT : 0°C to 230°C
- With option /HT : 0°C to 350°C
- With option /LT : -200°C to 150°C
For uid temperatures below -70°C select option /LT and ask
for special insulation (see also page 11-5).
According to the ange ratings:
- EN PN 16 : max. 16 bar
- EN PN 40 : max. 40 bar
- EN PN 63 : max. 63 bar
- EN PN 100 : max. 100 bar
- ASME class 150 : max. 16 bar
