Emerson IFT9701 Local display optional, Low-flow cutoff, Slug-flow inhibit, Fault indication

IFT9701 Specifications continued

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.

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

A.2.5 Damping

User-selected time constant of 0.1, 0.2, 0.4, 0.8, 1.6, 3.2, 6.4, or 12.8 seconds

A.2.6 Fault indication

Fault condition can be indicated by user-selected downscale (2 mA, 0 Hz) or upscale (22 mA, 7200 Hz) output levels, Bell 202 communications, and optional display

A.2.7 Output testing

Current source

Can output a specified current between 2 and 22 mA

Frequency source

Can output a specified frequency between 0.01 and 1200 Hz
