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, ULC, ATEX, IECEx etc.
•
Civil and structural good practices compliance
•
Contractual agreements or governmental compliance (or both)
•
In-situ performance test procedures
•
In-situ meter calibration
•
Field tested advanced meter health and flow dynamics diagnostics
•
Data collection and retention procedures

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

analog output (conventional)
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.
