1. Installation and Operation

The Hastings HFM-E-200 mass Flow-meter and HFC-E-202 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

1.1.Features

•LINEAR BY DESIGN. The HFM-E-200/HFC-E-202 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-E-200/HFC-E-202 series incorporates a removable/replaceable sensor module. Field repairs to units can be achieved with a minimum of production line downtime.

•LOW TEMPERATURE DRIFT. The temperature coefficient of span for the HFM-E-200/HFC-E-202 series is typically less than 0.05% of full scale/°C from 10-50°C. The temperature coefficient of zero is typically less than 0.1 % of reading/°C from 10-50°C.

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

output to

minimize environmental noise pickup.
