Calibration Adjust: Offset By ..... Enter a “+” or “-” offset value that is respec-
tively added to or subtracted from
measured flow readings for a linear offset
Set To ......... Enter measurement value (derived from
qualified reference instrument reading) to
linearly offset measured flow reading
NOTE:
Calibration is actually achieved by independently configuring each
sensor, which is a normal part of the initial setup.
Analog Outputs .......................... Two isolated 0/4-20 mA outputs; each with 0.004
mA (12-bit) resolution and capability to drive up
to 600 ohm loads; each output can be assigned
to represent one of these measurements:
•
Sensor A flow rate
•
Sensor B volume
•
Sensor B flow rate
•
Sensor C volume
•
Sensor C flow rate
•
Sensor D volume
•
Sensor D flow rate
•
Calculated measurement
•
Sensor A volume
NOTE:
Parameter (or calculated measurement) values can be entered to
define the endpoints at which the minimum and maximum mA output
values are desired (range expand).
Pulsed Outputs .......................... Two SPDT contact closures; each pulsed
output can represent a selected measured
volume, and activate at a user-set volume
increment for a desired time duration
Communication: RS-232 ........... Enables configuration and retrieval of measured
data for one analyzer using IBM-compatible PC
and optional GLI software tool kit
HART.............. Enables configuration and retrieval of measured
data for multiple analyzers over a communica-
tion link using appropriate hand-held terminal or
data system with HART software
Memory Backup (non-volatile) .... All user settings are retained indefinitely in
memory (EEPROM)
EMI/RFI Conformance................ Exceeds US and meets European standards
for conducted and radiated emissions and
immunity; certified CE compliant for applica-
tions as specified by EN 50081-1 for
emissions and EN 50082-2 for immunity
Electrical Certifications:
General Purpose (pending) ..... UL, C-UL, FM, and CENELEC
Class 1, Division 2 (pending) .. UL, C-UL, and FM: Groups A, B, C, D, F, and G
Zone 2 (pending) .................... CENELEC: Group IIC
Accuracy .................................... ± 0.1% of span
Sensitivity .................................. ± 0.1% of span
Repeatability .............................. ± 0.05% of span
Temperature Drift ....................... Zero and Span: ± 0.02% of span per
°
C
Response Time .......................... 1-60 seconds to 90% of value upon step change
Enclosure................................... NEMA 4X; polycarbonate face panel, epoxy-
coated cast aluminum door and case with four
1/2 inch (13 mm) conduit holes; nylon mount-
ing bracket, and stainless steel hardware
Mounting Configurations............. Panel, surface, and pipe (horizontal and
vertical) mounting
Net Weight ................................. 3.5 lbs. (1.6 kg) approximately
