Pre-installation considerations
•
Pipeline equipment code compliance, ANSI, ASME, etc.
•
Proper Inlet/outlet meter tube piping for reasonable stable flow to the settling chamber
(first meter tube spool upstream of the meter).
•
Electrical safety compliance: UL, CSA, ATEX, IECEx etc.
•
Civil and structural good practices compliance
•
Contractual agreements and/or governmental compliance
•
In-situ performance test procedures
•
Field tested meter health check and flow dynamics diagnostics
Installation manual
Channel B Phase options:
•
Lag forward, Lead reverse (Phase B lags
Phase A while reporting forward flow, leads
Phase A while reporting reverse flow)
•
Lead forward, Lag reverse (Phase B leads
Phase A while reporting forward flow, lags
Phase A while reporting reverse flow)
Phase A and Phase B output (based on flow
direction)
•
Reverse flow - output only reports flow in
the reverse direction. For frequency outputs,
Phase B of the output is 90 degrees out of
phase with Phase A.
•
Forward flow - output only reports flow in
the forward direction. For frequency outputs,
Phase B of the output is 90 degrees out of
phase with Phase A.
•
Absolute - output reports flow in both
directions. For frequency outputs, Phase B of
the output is 90 degrees out of phase with
Phase A.
•
Bidirectional - output reports flow on Phase A
only in the forward direction and on Phase B
only in the reverse direction.
Maximum frequency for the frequency outputs
•
1000Hz
•
5000Hz
•
(1) 4-20 mA independently configurable
analog output (HART

•
(1) 4-20 mA independently configurable
analog output (conventional) - Type 2 CPU
ONLY The analog output zero scale offset
error is within ±0.1% of full scale and gain
error is within ±0.2% of full scale.
The total output drift is within ±50 ppm of full
scale per °C.
