General Information
1. General Information
1.1. Overview
1.1.1. 400 Series Family
The Hastings 400 Series is a family of flow instruments which is specifically designed to meet
the needs of the industrial gas flow market. The “I” family in the 400 Series features an IP-65
enclosure which allows the use of the instrument in a wide variety of environments. The 400 I
products consist of four configurations: a flow meter, HFM-I-401, which has a nominal nitrogen
full scale between 10 SLM and 300 SLM and a corresponding flow controller, the HFC-I-403; a
larger flow meter, HFM-I-405, which ranges from 100 SLM to 2500 SLM, and a c or responding
flow controller, the HFC-I-407. These instruments are configured in a convenient in-line flowthrough design with standard fittings. Each instrument in the series can be driven by either a
+24 VDC power supply or a bipolar ±15 volt supply. The electrical connection can be made via
either a terminal strip located inside the enclosure or optionally through an IP-65 compatible
electrical connector. Also, these instruments include both analog and digital communications
capabilities.
1.1.2. 400 Series Meters
The Hastings HFM-I-401 and HFM-I-405 thermal ma ss flow meters are designed to provide very
accurate measurements over a wide range of flow rates and environmental conditions. The
design is such that no damage will occur from moderate overpressure or overflows and no
maintenance is required under normal operating conditions when using clean gases.
1.1.3. Measurement Approach
The instrument is based on mass flow sensing. This is accomplished by combining a hi gh-speed
thermal transfer sensor with a parallel laminar flow shunt (see Figure 1-1). The flow through
the meter is split between the sensor and shunt in a constant ratio set by the full scale range.
The thermal sensor consists of a stainless steel tube with a heater at its center and two
thermocouples symmetrically located upstream and downstream of the heater. The ends of the
sensor tube pass through an aluminum block and into the stainless steel sensor base. With no
flow in the tube the thermocouples report the same elevated temperature; however a forward
flow cools the upstream thermocouple relative to the downstream. This temperature
difference generates a voltage signal in the sensor which is digitized and trans ferred to the
main processor in the electronics enclosure. The processor uses this real-time information and
the sensor/shunt characteristics stored in non-volatile memory to calculate and report the
flow.
To ensure an inherently linear response to flow, both the thermal sensor and the shunt have
been engineered to overcome problems common to other flow meter designs. For example,
nonlinearities and performance variations often arise in typical flow meters due to pressurerelated effects at the entrance and exit areas of the laminar flow shunt. Hastings has designed
the 400 Series meters such that the flow-critical splitting occurs at locations safely downstream
from the entrance effects and well upstream from the exit effects. This vastly improve s the
stability of the flow ratio between the sensor and shunt. The result of this design feature is a
better measurement when the specific gravity of the flowing medium varies, for instance due
to changes in pressure or gas type. Also, a common problem in typical flow meters is a slow
response to flow changes. To improve response time, some flow meter designs introduce
impurities such as silica gel. Alternatively, Hastings has designed the 400 Series sensor with
reduced thermal mass to improve the response time without exposing additional materials to
the gas stream.

1.1.4. Additional Functions
These instruments contain a number of functions in addition to reporting flow which include:
• Settable alarms and warnings with semiconductor switch outputs
• A digitally reported status of alarms and warnings such as overflow/underflow
• A flow totalizer to track the amount of gas added to a system
• A digitizing channel for an auxiliary analog signal
• An internal curve fitting routine for “fine tuning” the base calibration
• An alternate calibration set of 8 different ranges/gases

Installation
2. Installation
Many of the functions described in this section require
removing the enclosure front plate. Care must be taken when
reinstalling this plate to ensure that the sealing gasket is
properly positioned and the fasteners are secure to maintain
CAUTION
2.1. Receiving Inspection
Your instrument has been manufactured, calibrated, and carefully packed so it is ready for
operation. However, please inspect all items for any obvious signs of damage due to shipment.
Immediately advise Teledyne Hastings and the carrier if any damage is suspected.
Use the packing slip as a check list to ensure all parts are present (e.g. flow meter, power
supply, cables etc.) and that the options are correctly configured (output, range, gas,
connector).
If a return is necessary, obtain an RMA (Return Material Authorization) number from Teledyne
Hastings’ Customer Service Department at 1-800-950-2468 or
hastings_instruments@teledyne.com
2.2. Environmental and Gas Requirements
an IP65 compliant seal.
.
Use the following guidelines prior to installing the flow meter:
• Ensure that the temperature of all components and gas supply are
between -20° and 70° C
• Ensure that the gas line is free of debris and contamination
• Ensure that the gas is dry and filtered (water and debris may clog the
meter and/or affect its performance)
• If corrosive gases are used, purge ambient (moist) air from the gas lines
2.3. Mechanical Connections
The meter can be mounted in any orientation unless using dense gases or pressures higher than
250 psig in which case a “flow horizontal” orientation is required. The meter’s measured flow
direction is indicated by the arrow on the electronics enclosure.
A straight run of tubing upstream or downstream is not necessary for proper operation of the
meter. The flow meter incorporates elements that pre-condition the flow profile before the
measurement region. So for example, an elbow may be installed upstream from the flow meter
entrance port without affecting the flow performance.
Compression fittings should be connected and secured according to recommended procedures
for that fitting. Two wrenches should be used when tightening fittings (as shown in the Quick
Start Guide on page iii) to avoid subjecting the flow meter body to undue torque and related
stress.
The fittings are not intended to support the weight of the meter. For mechanical structural
support, four mounting holes (#1/4-20 thread, 3/8” depth) are located in the bottom of the
meter. The position of these holes is documented on the outline drawing in Appendix 3 (Section
6.3).
Leak-check all fittings according to an established procedure appropriate for the facility.

2.4. Mounting the Electronics Remotely
In order to maintain the integrity of the Electrostatic Discharge
immunity both parts of the remote mounted version of the
HFM-I-400 instrument must be screwed to a well grounded
structure. The ferrite that is shipped with the instrument must
CAUTION
The electronics enclosure can be separated and
relocated up to 30 feet away from the flow
meter base. This requires a cable which is
supplied with the instrument if ordered as a
cable mounted unit. Alternatively, a 2, 5, or 10
meter cable can be purchased separately. See
section 4.2 for ordering information and part
numbers.
When remote mounting the electronics
enclosure, the support bracket can remain
attached to either the flow meter base or the
electronics. To separate the electronics
enclosure from the support bracket, remove
the two screws located on the back of the
support bracket. To separate the flow meter
base from the support bracket, remove the four
screws that mount the bracket to the top of the
flow meter base. Unscrew the electrical
connector between electronics enclosure and the flow
meter base. Remove the electronics enclosure from the
flow meter base. Connect the female end of the remote
electronics cable to the flow meter base and the male end
to the electronics enclosure. The electronics enclosure can
be mounted remotely by using the two threaded holes in
the enclosure. The size and spacing of these two holes are
specified on the outline drawing in Appendix 3 (Section
6.3). These holes may be used by inserting fasteners from
behind through a new mounting bracket or they may be
accessed from the front side by temporarily removing the
enclosure panel. This enables mounting the enclosure to a
wall or other solid structure. Alternatively, if the
instrument was originally configured as a bracket mounted
unit the bracket may be directly mounted to a support
structure. The bracket mounting holes locations are the
same as those for the flow meter base mounting. (See the
outline drawing in Appendix 3, Section 6.3.)

2.5. Electrical Connection
There are two electrical connectors on the Hastings 400-I
Series flow meters—an analog terminal strip (located within
the electronics enclosure) and a digital connector. The
analog connector provides for the power supply to the
meter along with analog signals and functions. As such, its
use is required for operation. The digital connector is used
for communications in either of RS232, RS485, or Ethernet
mode depending on the instrument’s configuration. The digital connector does not have to be
used if the meter is operated as an analog-only instrument.
