1. 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 corresponding flow controller, the HFC-I-407. These
instruments are configured in a convenient in-line flow-through 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 mass 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 high-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
transferred 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 pressure-related effects at the entrance
and exit areas of the laminar flow shunt. Hastings has designed the 400 Series meters such that the flowcritical splitting occurs at locations safely downstream from the entrance effects and well upstream from
the exit effects. This vastly improves 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
401-405 SERIES - 1 -
• 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

2. Installation
CAUTION
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 an IP65 compliant seal.
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
• 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.
