Note: To determine if the FT4X 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.

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):w/o Retractor: 740 psig (51.02 barg)
                                   with Retractor: 150 psig (10.3 barg)

316 SS inline w/NPT ends: 300 psig (20 barg)
316 SS inline w/150lb flanges: 230 psig (16 barg)
CS inline w/NPT ends: 300 psig (20 barg)
CS inline w/150lb flanges: 285 psig (20 barg)

Check with factory for higher pressure options.
NOTE: When teflon ferrule option ordered, gas pressure is 60psig (4.1 barg) maximum.

Relative Humidity:

90% RH maximum; non-condensing
NOTE: Condensing liquids contacting the sensor can cause erratic flow indication.

Temperature:

DDC-Sensor™: -40 to 250°F (-40 to 121°C)
Enclosure: -40 to 158°F (-40 to 70°C)
Remote Sensor Enclosure: -40 to 158°F (-40 to 70°C)

Note: Display dims below -4°F (-20°C); function returns once temperature rises again.

Input Power:

Input power: 12 to 28 VDC, 6 watts max. (CE requirement)
Full input power input range: 10 to 30 VDC.

Inputs/Outputs

4-20mA Channel 1:

  • Standard isolated 4-20mA output configured to indicate for flow; fault indication per NAMUR NE43. HART communication option.
  • The 4-20mA load resistance must be 125 ohms or less when operating on 12 volt power and 600 ohms or less on 24 volt power.

4-20mA Channel 2:

  • Standard isolated 4-20mA output configured to indicate either flow or temperature.

Pulse/Alarm:

  • Isolated open collector output rated for 5 to 24VDC, 10mA maximum load, 0 to 100Hz (the pulse output can be configured to either transmit a 0 to 100Hz signal proportional to flow rate or an on/off alarm).

Remote Switch Input:

  • Can be configured to reset the flow totalizer and elapsed time.

Port:

Micro USB communication port is standard.

Software:

The free PC-based software tool - FT4X View™ - provides complete configuration, remote process monitoring, and data logging functions.

Optional serial communication:

HART or Modbus RTU (RS485).

4-20mA and Pulse Verification:

Simulation mode used to align 4-20mA output and pulse output (if ordered) with the input to customer’s PLC/DCS.
