GMFLOW02

MICROPROCESSOR MODULE
for MEASUREMENT and VISULIZATION
air flow rate, air speed in piping, differential pressure, and fluid temperature if the meter is equipped with temperature probe GMSTN415D-EX or GMSTN425D-EX, consisting of the microprocessor module and pitot tube with the length indicated by the final number in the code [measurement in inches].

Air flow data shown at the centre of the display.
Alternating display of air speed (greater than 2 m/s) and differential pressure data.
Visualization of detected temperature data [if the temperature probe is present] or the value set by the user [default 25°C].

Display: 128 x 64 pixel backlit.

inputs: 

• analog 4-20mA
• pressure

Outputs:

• analog 4-20mA
• analog 0-10V
• serial RS485
• digital on two relays, fully customized using internal device software

Output 24Vdc 200mA to power external devices
Power 1: from 85Vac to 264Vac [from 47Hz to 440Hz]

or from 127Vdc to 370Vdc

Power 2: 24Vdc ± 10%

Both power supplies are included standard.
Operating temperature: -20°C/+60°C
Front protection: IP54

Please note that, for correct installation, the Pitot tube must be positioned at the center of the duct in which it will be installed.
The table below also indicates the length of the Pitot tube.
