The above typical service power selections are for reference only. De-
pending on application requirements, surface temperature rating require-
ments, and rangeability expectations, alternate power selections may be
recommended. Other intermediate power selections can be made.
Relay Rating
Standard: Dual alarm, SPDT or single alarm DPDT field
configurable, 6 amps resistive load at 240 VAC, 120 VAC, 24 VDC.
Optional: Dual alarm SPDT or single alarm DPDT field configurable
hermetically sealed relay, 0.5 amps at 115 VAC/2 amps at 28 VDC.
Electrical Enclosure
Aluminum (epoxy coated) or optional stainless steel. Enclosures are
rated for hazardous location use (Class I and II, Division 1 and 2,
Group B, C, D, E, F and G; and EEx d IIC) and weather and corrosion
resistant (NEMA and CSA Type 4X and equivalent to IP66).
Operating Temperature
Ambient -40 °F to +140 °F [-40 °C to + 60 °C]

Air/Gas:
0.25 SFPS to 120 SFPS [0.08 NMPS to 37 NMPS] 0.25 watt heater
at standard conditions; 70 °F [21.1 °C], 14.7 psig [1.013 bar(g)].

Factory Calibrated Switch Point Accuracy
Any flow rate within the instrument flow range may be selected as a
setpoint alarm. A factory-calibrated setpoint adjustment may be
optimally preset with accuracy of ±2% of setpoint velocity over an
operating temperature range of ±50 °F [±28 °C].
Monitoring Accuracy
Based on the non-linear output voltage (P1, pins 1 & 2) over the en-
tire flow range, a 100 °F (56 °C) max. temperature span, and a max.
operating pressure range of ±100 psig [±7 bar(g)]:
Liquids: ±5% reading or ±0.04 SFPS [±0.012 NMPS], whichever is larger.
Gases: ±5% reading or ±2 SFPS [±0.61 NMPS], whichever is larger.
Repeatability
±0.5% reading
For Level/Interface Service
Accuracy
Models S, B
±0.25” [±6.4 mm]
Model F
±0.1” [±2.5 mm]
Repeatability
Models S, B
±0.125” [±3.2 mm]
Model F
±0.05” [±1.3 mm]
For Temperature Service
Accuracy
±2.0 °F [±1 °C] with field setpoint adjustment. Monitoring accuracy
±3.5 °F [±2 °C] with standard curve fit output voltage operation
across the selected instrument temperature range. Higher accuracy
available with factory calibrations.
Repeatability
±1.0 °F [±0.6 °C]
The above accuracy is based on liquid or slurry service and in gas service
with a minimum 1 SFPS [0.3 NMPS] velocity past the sensing element or
with the heater deactivated for temperature sensing service only.
SIL:
SIL-2 compliant, safe failure fraction (SFF) 82% to 84%
Factory Application-Specific Setup and Setpoint Calibration
Standard instrument factory default settings (unless otherwise
selected at order entry):
• 120 VAC input power for all domestic units.
• 230 VAC for all other agency approval units. Field selectable.
• Dual SPDT alarms set for:
Alarm No. 1
: Preset for flow or level and to de-energize with
decreasing conditions.
Alarm No. 2
: Preset to de-energize for increasing temperature at
10 °F [5 °C] below the maximum instrument process temperature.
• Heater power at 0.25 watt on Model F or 0.75 watt on Model S/B.
• Mode switch set to “operate”.
Factory calibration including set up for specific service, process fluid
and alarm conditions optionally available. Contact factory for fluid
handling capabilities.
