Relays: Two Relays independently adjustable: 2 amps bifurcated gold plated DPDT contacts, 0-2.0
amps at 28 Vdc or 115 Vac resistive, 0.1 volts at 230 Vac resistive. 0 amps (or Dry) rating is good if load
is kept below 30mA.
Slave Relay Energization Terminals: Customer provided relay may be energized at programmable
values connecting to points on the output terminal strip.
+Ext Relay: 20 Vdc, sourcing up to 100 mA total both relay outputs.
-Ext Relay: Open/Ground (switching).
Power Input: 115 Vac, ±15 Vac, 16 watts maximum or 230 Vac, ±30 Vac, 50/60Hz, 16 watts
maximum; or 24 Vdc, -2 and +6 Vdc, 16 watts maximum as selected by the power input switch and
terminal selection.
Indicator Display & Built-In Keypad: 4 lines by 20 character liquid crystal display that may be
programmed to indicate flow rate, total flow, temperature, and switch point status in customer
determined English or Metric (SI) values. Keypad permits easy touch programming to change zero,
span, switch points, and units of measurement and for instrument verification, trouble shooting and
other critical instrument functions.
Electrical Enclosures
Fiberglass NEMA/CSA Type 4X is standard. All aluminum and stainless steel enclosures are rated for
hazardous location use (Class I and II, Division 1 and 2, Groups B, C, D, E, F and G; and EEx d IIC)
and resists the effect of weather and corrosion (NEMA/CSA Type 4X and equivalent to IP66).
Electrical Connection: 1 inch female NPT.
Temperature Range: 0°F to +150°F (-18°C to +65.6°C).
Flow
Accuracy: ±1% reading + 0.5% full scale.
Repeatability: ±0.5% reading or better.
Turndown Ratio: Field set to within specified flow range from 2:1 to 1000:1. Turndown ratios up to
1000:1 are possible in some applications. Signal output may be field set to be zero or non-zero based.
Up to three independent calibrations may be stored in the GF Series transmitter and selected via the
built-in keypad, RS-232C Serial Port or Auxiliary Input Terminal (4-20 mA).
Calibration Adjustment: Up to three independent calibration groups are available. Each group is
precisely calibrated at the factory in accordance with the submitted Application Data Sheet to
turndown ratios as high as 1000:1. Most calibrations are performed in the actual process fluid and
process conditions described by the customer’s specification. Adjustment to zero and span are made
easily in the field by using the keypad to input revised flow or temperature range information.
Temperature
Accuracy: ±2°F (±1.1°C ). Valid only above minimum flowing conditions of 5 SFPS (1.5 NMPS).
Repeatability: ±1°F (±0.55°C).
System Approvals
Factory Mutual Research (FM), CSA, CE Mark, CENELEC, CRN and ATEX.
