The Hastings HFM-210 mass Flowmeter   and HFC-212 flow controller  are  designed to accurately measure 

and control mass flow over the range of 10 sccm to 30 slm, without corrections or compensations for gas 
pressure and temperature with an accuracy of better than ±1% FS.  Hastings mass flow instruments do not 

require any periodic maintenance under normal operating conditions with clean gases.  No damage will occur 
from the use of moderate overpressures   (~500 psi/3.45MPa) or overflows. Instruments are normally 

calibrated with the appropriate standard calibration gas (nitrogen) then a correction factor is used to adjust the 
output for the intended gas.  

•  LINEAR BY DESIGN.  The HFM-210/HFC-212 series is inherently linear (no linearization circuitry is 

employed).  Should recalibration in the field be desired (a calibration standard is required),  the customer 

needs to simply set the zero and span points.  There will be no appreciable linearity change of the instrument 
when the flowing gas is changed. 

•  MODULAR SENSOR.  The HFM-210/HFC-212 series incorporates a removable/replaceable sensor module.  

Field repairs to units can be achieved with a minimum of production line downtime.  

•  METER SETTLING TIME.  Changes in flow rate for the HFM-210 are detected in less than 2 seconds when 

using the fast-response circuitry. 

•  LOW TEMPERATURE DRIFT.  The temperature coefficient of span for the HFM-210/HFC-212 series is 

typically less than 0.08% of full scale/°C from 15-45°C.  The temperature coefficient of zero is typically less 

than 0.15 % of reading/°C from 0-50°C. 

•  CURRENT LOOP.  The 4-20 mA option gives the user the advantages of a current loop output to minimize 

environmental noise pickup.
