makes no expressed or implied guarantees of corrosion resistance of mass flow
meters as pertains to different flow media reacting with components of meters. It is the
customers' sole responsibility to select the model suitable for a particular gas based on the
fluid contacting (wetted) materials offered in the different models.
INLET AND OUTLET CONNECTIONS:
FMA1700A/1800A Series Max. Flow 10 and 50 L/min : 1/4" compression fittings.
Optional: 6mm compression, 1/4" VCR ® , 3/8" or 1/8" compression fittings (Max. Flow 10).
FMA1700A/1800A Series Max. Flow 100 and 200 L/min : 3/8" compression fittings.
FMA1700A/1800A Series Max. Flow 500 L/min: 1/2" compression fittings.

compression fittings.
LCD DISPLAY: 3½ digit LCD (maximum viewable digits “1999”), 0.5 inch high characters.
On FMA1700A/1800A aluminum or stainless steel models the LCD display is built into the
upper block element and may be tilted over 90 degrees for optimal viewing comfort.
Remote or panel mounting remote reading is optional.
Standard readings are in direct engineering units for the given gas and flow rate (i.e.
liters/minute [lpm], standard cubic centimeters/minute [sccm], standard cubic feet/hour
[scfh], etc.). 0 to 100% LCD calibration scaling is available upon request at time of order.
