Liquid Meter specifications
•
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
Analog Output(s)
•
(1) 4-20 mA independently configurable
analog output (HART)
•
(1) 4-20 mA independently configurable
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.

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
