Operating Specifications

Type Insertion Inline
Flow Units (field selectable): SCFM, SCFH, NMPS, NM3/M, NM3/H, NM3/D, NLPS, NLPM, NLPH, MCFD, MSCFD, SCFD, MMSCFD, MMSCFM, SM3/M, SM3/D, SM3/H, LB/S, LB/M, LB/H, LB/D, Kg/S, Kg/M, Kg/Hr, SLPM, SFPM, MT/H
 Flow Rates: 15 to 25,000 SFPM (0.07 to 120 NMPS)
Turndown: up to 1000:1; 100:1 typical
Flow Ranges:
Pipe Size SCFM NM³/HR
1.5″ (40mm) 0 – 354 0 – 558
2″ (50mm) 0 – 583 0 – 920
2.5″ (63mm) 0 – 830 0 – 1,200
3″ (80mm) 0 – 1,280 0 – 2,020
4″ (100mm) 0 – 2,210 0 – 3,480
6″ (150mm) 0 – 5,010 0 – 7,910
8″ (200mm) 0 – 8,680 0 – 13,700
10″ (250mm) 0 – 13,600 0 – 21,450
12″ (300mm) 0 – 19,400 0 – 30,600
Note: To determine if the FT4A will operate accurately in other pipe sizes, divide maximum flow rate by the pipe area. The application is acceptable if the resulting velocity is within the velocity range above.
Pipe Size SCFM NM³/HR
0.75″ (20mm) 0 – 93 0 – 146
1″ (25mm) 0 – 150 0 – 237
1.25″ (32mm) 0 – 260 0 – 410
1.5″ (40mm) 0 – 354 0 – 558
2″ (50mm) 0 – 538 0 – 920
2.5″ (63mm) 0 – 830 0 – 1,200
3″ (80mm) 0 – 1,280 0 – 2,020
4″ (100mm) 0 – 2,210 0 – 3,480
6″ (150mm) 0 – 2,500 0 – 3,950

Note: Consult factory for flow ranges above those listed. Inline meters above 5,000 SCFM (7,900 NM3/H) air may require third party calibration.

Gas Pressure (max): 740 psig (51 barg) 316 SS inline w/NPT ends: 300 psig (20 barg)

Inputs/Outputs
  • All outputs and communication circuits are galvanically isolated.
  • Standard 4-20mA output proportional to the flow rate; fault indication per NAMUR NE43; HART communication option.
  • Second output for pulse, Modbus RTU (RS485), or BACnet MS/TP (RS485).
  • Isolated pulse output: 5 to 24VDC, 10mA max, 0 to 100Hz for flow.
  • The pulse output can be used as an isolated sold state output for alarms.
Port:
Mini USB communication port is standard.
Software:
