The mass and volumetric
flowmeters of FMA-1600A
Series use the principle of
differential pressure within a
laminar flow field to deterime the
mass flow rate. A laminar flow
element (LFE) inside the
meter forces the gas into laminar
(streamlined) flow. Inside this
region, the Poiseuille equation
dictates that the volumetric flow
rate be linearly related to the
pressure drop along a fixed
distance of the LFE. This, along
with the viscosity of the gas, is
used to accurately determine the
volumetric flow rate. Separate
absolute temperature and
pressure sensors are incorporated
and correct the volumetric flow rate
to a set of standard conditions. This
standardised flow rate is commonly
called the mass flow rate and is
reported in units such as standard
cubic feet per minute (SCFM) or
standard litres per minute (SLM).
Standard units include a 0 to 5 V
output (4 to 20 mA optional) and
RS232 communications. The gas
select feature can be adjusted from
the front of the keypad or via RS232
communications. Volumetric flow,
mass flow, or absolute pressure, and
temperature can be viewed or recorded
through the RS232 connection. It is also
possible to multi-drop up to 26 units
on the same serial connection to a
distance of 38 metres. These flowmeters
can be powered by the optional battery
pack FMA1600-BP for use in the field.
SPECIFICATIONS
Accuracy: ±(0.8% of rdg + 0.2% FS)
Repeatability: ±0.2%
Turndown Ratio: 200:1
Response Time: 10 ms typical default response time for 63.2% of a step change. A variable register allows response time to be field adjustable to a certain extent via RS232 communications. The primary trade-off for response time is signal noise
Output: 0 to 5 Vdc standard
Operating Temperature: -10 to 50°C (14 to 122°F)
Zero Shift: 0.02% FS/°C/atm
Span Shift: 0.02% FS/°C/atm
Humidity Range: 0 to 100% non-condensing
Pressure (Max):
FMA-1600A Series: 145 psig
FMA-1600A Series: 50 psi differential
FVL-1600A Series: 10 psig
FVL-1600A Series: 10 psi differential
Measurable Flow Rate: 125% FS
Supply Voltage: 7 to 30 Vdc (15 to 30 Vdc for 4 to 20 mA output)
Supply Current: 35 mA typical current draw; 100 mA available supply recommended
Cable Connection: 8-pin mini DIN

Note: Comes complete with 24 Vdc power supply with 1.8 m of cable, 8 pin male mini DIN connector, operator’s manual and NIST certificate.
††Portable versions "-B" have an integral battery compartment and come complete with 24 Vdc power supply, 8 pin male mini DIN connector, operator's manual, NIST certificate, and 9V battery installed. Portable version is not available on models with 4 to 20 mA output.
Units are calibrated to air @ 5 psig for 0 to 1 LPM, 15 psig for 2 to 10 LPM, 30 psig for 20 to 100 LPM, and 50 psig for 200 LPM and greater.
Calibrations done at ambient (21°C/70°F) temperature only.
To replace the standard RS232 communications with RS485, add suffix "-RS485" to the model number, contact sales for additional price.
Standard output is scaled to the mass flow rate. For volumetric flow rate as standard output add "-VOL" to the model number.
Optional secondary output are scaled the same as the primary output. For a different secondary output scale add suffix "-T" for temperature or suffix "-P" for pressure, no additional cost.
Add "-SCFH" to model number for units scaled in SCFH, no additional charge. Specify required range in SCFH.
For totalizer option, add suffix "-TOT" to the model number, contact sales for additional price. Please specify resolution. This is a 6-digit counter. Examples: For totalizing in litres with 1/100 litre resolution, the max count would be 9999.99. For totalizing in litres with 1 litre resolution, the max count would be 999999.
High accuracy calibrations to ±0.5% of full scale are available on models having a minimum full scale range of 10 SCCM or greater. For a high accuracy calibration add suffix "-HACAL" to the model number, contact sales for additional price.
For a Remote Display, add suffix "-RD-*FT" to the model number, contact sales for additional price. Replace the * in the suffix with the required length in whole feet, the maximum length is 12'. Please note the optimum distance in feet is between 9 to 10'.
