1. General Information

The Hastings HFM-201/HFM-205/HFC-203/HFC-207 series Mass flow meters (HFM-201/HFM-

205) and controllers (HFC-203/HFC-207) are designed to accurately measure and control mass
flow over the range of 30 slm to 2500 slm, without corrections or compensations for gas pressure
and temperature with an accuracy of better than ±1% from the mean (±2% FS for 201/203 units in
the ½” fitting size base with flows >500 slm). 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/3.45 MPa) 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. Special calibrations for other gases, such as oxygen, helium
and argon, are available upon special order.

1.1. Features

• LINEAR BY DESIGN. The Hastings 200 series flow instrument 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 Hastings 200 series flow instrument 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-201/HFM-205 are detected in less than 2

seconds when using the speed up circuitry.

• LOW TEMPERATURE DRIFT. The temperature coefficient of span for the Hastings 200 series flow

instrument is typically less than 0.05% of full scale/° C from 15° - 45° C. The temperature coefficient of
zero is typically less than 0.1% of reading/° C from 0° - 50° C.

• FIELD RANGEABLE. The HFM-201/HFC-203 series is available in ranges from 30 slm to 1100 slm.

The HFM-205/HFC-207 series is available in ranges from 1000 slm to 3000 slm. For HFC-203 & HFC­207 controllers, an orifice change is required as well. Calibration is required after all changes.

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

minimize environmental noise pickup.

1.4. Optional 4 - 20 mA Current Output

An option to the standard 0 - 5 VDC output is the 4 - 20 mA current output that is proportional to
flow. The 4 - 20 mA signal is produced from the 0 - 5 VDC output of the flow meter. The current
loop output is useful for remote applications where pickup noise could substantially affect the
stability of the voltage output or long cable runs where cable resistance would cause a voltage signal
to decay.

The current loop signal replaces the voltage output on pin 6 of the DA-15 connector (pin 2 of DE-9
24 Volt). The current loop is sourced internally from the +15 VDC supply and must be returned to
the signal supply common after (pin 5 [±15VDC] or pin 8 [24 VDC]) passing through the
monitoring circuitry to complete the loop. The load must be between 0 and 600 Ohm.

The 4 - 20 mA I/O option can accept a current input for flow controllers. The 0 - 5 VDC command
signal on pin 14 (pin 3 for 24 Volts) can be replaced by a 4 - 20mA command signal. The loop
presents an impedance of 50 Ohms and is returned to the signal common. On the 24 Volt units, the
signal common will need to be tied to the power supply common external to the flow controller to
complete the loop since the signal common is galvanically isolated internally from the supply
common. This line must be current limited (<50 mA) to prevent short circuit currents from
damaging the receiving circuit in the flow controller.

1.5. Other Accessories

1.5.1. Hastings Power Supplies

Hastings power supply/display units are available in one and four channel versions. They convert
100, 115 or 230VAC to the ±15 VDC required to operate the flow meter and provide a digital
indication of the flow rate. Interface terminals for the retransmission of the flow meter analog output
signal are located on the rear of the panel.

The THCD-100 and the THPS-100/400 models are built with controllers in mind but will work
with meters as well. The Model 40 is for flow meters only. Throughout this manual, when
reference is made to a power supply, it is assumed the customer is using a Hastings power supply.
Hastings THCD and THPS power supplies are CE marked, but the Model 40 does not meet CE
standards at this time. The Model 40, The THCD and THPS-100 are not compatible with 4 – 20
mA analog signals. With the THPS-400, individual channels’ input signals, as well as their
commands, become 4 – 20 mA compatible when selected. The THPS-400 also sports a Totalizer

feature. More information about Hastings Instruments’ power supplies can be found on the
Hastings web site. http://www.teledyne-hi.com/products/powerpod-series.htm

1.5.2. Interconnecting Cables

Cables are available from Hastings, in various lengths, to connect from the 15 pin "D" connector on
the back of Hastings power supplies directly to any of the 200 series and 300 series flow instruments
(including digital versions). More information about the available cables can be found in the THPS
400 bulletin on the Hastings web site. http://www.teledyne-hi.com/pdfs/bulletins.htm
