A.2.2
Local display (optional)
5-digit, alphanumeric, liquid crystal display (LCD) installed on the field-wiring compartment cover.
The LCD shows flow rate, and indicates slug flow, flowmeter zeroing in progress, and electronic
faults.
The LCD shows flow rate, and indicates slug flow, flowmeter zeroing in progress, and electronic
faults.
Note: Not available for ATEX Zone 1 applications.
A.2.3
Low-flow cutoff
Flow rate below cutoff causes outputs to default to level that indicates zero flow and totalizer stops
counting

A.2.4
Slug-flow inhibit
When transmitter senses density outside user-selected limits, outputs default to levels indicating zero
flow and totalizer stops counting
