1. General Information
The Hastings 200 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) and 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.
NOTICE: The instruments described in this manual may be available with multiple pinouts.
Ensure that all electrical connections are correct.
NOTICE: The instruments described in this manual are designed for INDOOR and DRY use only.
NOTICE: The instruments described in this manual are designed for Class 2 installations in
accordance with IPC standards.
CAUTION: There are no operator serviceable parts or adjustments inside the product.
CAUTION: If this equipment is used in a manner other than that specified, the protection
provided by the equipment may be impaired.

Features
STABILITY. The Hastings HFM-201/203/205/207 instruments operate on a unique thermal electric principle
using a heated metallic capillary tube and thermocouple temperature measurement. This results in an output
that is stable with time.
THERMAL MASS FLOW MEASUREMENT. The 200 Series sensor output is a function of the mass flow rate and the
heat capacity of the gas. Changes in gas composition usually only require a simple multiplier to account for the
difference in heat capacity. This gas conversion factor allows Hastings flowmeters to measure a wide variety
of gases.
LINEAR BY DESIGN. The HFM-201/203/205/207 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.
MODULAR SENSOR WITH LOCKING CONNECTOR. The HFM-201/203/205/207 Series incorporates a
removable/replaceable sensor module with a reliable sensor to board connection. Field repairs to units can be
achieved with a minimum of production line downtime with confidence in the sensor to PCB connection.
SETTLING TIME. Filtering in the meter circuitry and more modern valve circuitry have improved the standard
200 Series response time in meters and controllers. Dual-stage valve controllers perform 10-100% flow changes
in about 6 seconds. 200 Series flow meters perform 0-100% in under 6 seconds.
LOW TEMPERATURE DRIFT. 200 series flow instruments have a thermal coefficient of span that is no more
than 0.06% of full scale/°C from -20 to 70°C and a thermal coefficient of about 0.035% of reading/°C from -20
to 70°C.
CURRENT LOOP. The 4-20 mA option gives the user the advantages of a current loop output to minimize
environmental noise pickup.
FLEXIBLE POWER REQUIREMENTS. 200 series instruments using the 24V board can operate with power
supplies capable of providing 11 –36 VDC via the 9-pin D connector provided the supply meets the current
requirements (see sections 1.2 and 1.3).

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 [±15 VDC] 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 –20 mA 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.

Accessories
1.5.1. Power Supplies
Hastings power supplies are available in one or four channel versions. They convert 100, 115 or 230VAC
to the voltage required to operate the instruments and provide a digital indication of the flow rate.
Hastings power supplies are power limited to no more than 150 VA max (fused) and use a switch
compliant to EN 60601-1. Interface terminals for the analog output signals and a main power on/off
switch are located on the rear panel as well. For safety reasons it is recommended that the power
supply (and on/off switch) be kept near the flow instruments and that the on/off switch not be blocked.
Throughout this manual, when reference is made to a power supply, it is assumed the customer is using a
Hastings power supply. Designs and models offered as Hastings Power supplies change as new technology
becomes available. For knowledge of the most up-to-date Hastings power supplies, please consult either
Hastings sales staff or our website at http://www.teledyne-hi.com
WARNING: To prevent the spread of fires in the event of a fault, only use power supplies power
limited to no more than 150 VA. The current available from a power supply used with a 200
series instrument should be no greater than 1.6 A. Hastings power supplies meet these
requirements.
1.5.2. Cables
Cables to power Hastings flow instruments connect from the 15 pin "D" connector on the back of the
power supply directly to any of the 200 series flow instruments. More information about the available
cables can be found on our website at http://www.teledyne-hi.com
