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.

Installation 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.
2.4. Mounting the Electronics Remotely CAUTION 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 be installed on the cable next to the electronics enclosure. The electronics enclosure can be separated and relocated up to 30 feet away from the flow meter base.
CAUTION In order to maintain the environmental integrity of the enclosure the power/signal cable jacket must have a diameter of .157 - .315” (4 – 11 mm). The nut on the cable gland must be tightened down sufficiently to secure the cable. This cable must be rated for at least 85°C. 2.5.1. Power Supply Ensure that the power source meets the requirements detailed in the specifications section. Hastings offers several power supply and readout products that meet these standards and are CE marked.
Figure 2-4 shows an arrangement using a separate loop supply which is isolated from the instrument power supply.
2.5.2.2. Voltage output If the flow meter is configured for a voltage output, the signal will be available as a positive potential on pin 4 relative to pin 3 of the terminal strip. Since these pins are galvanically isolated, the signal cannot be read by an indicator between pin 4 and pin 1 of the terminal strip. Pin 3 must be used as the return to properly read the output on pin 4. If an output that is referenced to power supply common is desired then pins 3 and 1 must be connected.
electronics enclosure. Only the state of jumpers 1, 2, and 5 affect the RS-232 operation. These jumpers are installed vertically over two pins when enabled and are numbered from left to right. Jumper 1 must be disabled for RS-232; jumper 2 is used to select half or full duplex; and jumper 5 is enabled when a hardware override of the baud rate (forcing it to 9600) is desired. These functions are summarized in Figure 2-6. 2.7.2.
2.8. Alarm Output Connection The Hastings 400 Series flow meters include two software settable hardware alarms. Each is an open-collector transistor functioning as a semiconductor switch designed to conduct DC current when activated. (See Figure 2-9.) These sink sufficient current to illuminate an external LED or to activate a remote relay and can tolerate up to 70Vdc across the transistor. The alarm lines and the alarm common are galvanically isolated from all other circuit components.
2.9. Auxiliary Input Connection The Hastings 400 Series flow meters provide an auxiliary analog input function. The flow meter can read the analog value present between pins 5 and 6 on the terminal strip (as shown in Figure 2-2) and make its value available via the digital interface. The accepted electrical input signal is the same as that configured for the analog output signal (4 – 20 mA, 0 -20 mA, 0-5 Vdc, 1-5 Vdc, or 0-10 Vdc).
Calibrated gas = Nitrogen (GCF1 = 1.000) Full scale range (FS1) = 100 slm Secondary gas (FS2) = Hydrogen (GCF2 = 1.0038) 1.0038/1 = 1.0038, 1.0038 x 100 = 100.38 slm of Hydrogen Example 2- Changing the active gas record Selecting the active gas record is accomplished in one of two ways: 1. Hardware setting 2. Software setting Hardware: The hardware setting is selected by accessing a rotary encoder on the upper PC board in the electronics enclosure.
Check mounting and mechanical installation including flow direction Insure flow connections are leak tight Check digital M12 connector and/or cable Verify power connections on analog terminal strip + Vsup → pin 1 - Vsup → pin 2 Check Model # and Software Revision S1 Verify output and other connections on analog terminal strip (See Section 2.
Operation 3. Operation The Hastings 400 Series flow meters are designed for operation with clean dry gas and in specified environmental conditions (See Section 1.2). The properly installed meter measures and reports the mass flow as an analog signal and, depending on the configuration and set up, as a digital response. Other features can assist in the measurement operation and provide additional functions.
3.3.1. Digitally Reported Flow Output The flow rate can be read digitally by sending an ascii “F” command (preceded by the address for RS-485). The instrument will respond with an ascii representation of the numerical value of the flow rate in the units of flow specified on the nameplate label. Example: A meter with RS-232 communications, calibrated for 500 slm FS N2 Computer transmits: {F} HFM flow meter replies: {137.5} This is interpreted as 137.5 slm of nitrogen equivalent flow.
Stability – The flow meter must stabilize for at least 3 minutes at zero flow, especially following a high flow or overflow condition. This will allow all parts of the sensor to come to thermal equilibrium resulting in the best possible zero value. 3.4.2. Adjusting Zero The pre-conditions required for a zero check must also be followed when making a zero adjustment. The zero adjustment is a digitally controlled “reset” type operation.
3.6. Warnings/Alarms Pressure Effect 8 7 Span Shift (% Reading) The gas properties which form the basis for the flow measurement, such as viscosity and specific heat, exhibit a slight dependence on the gas pressure. Fortunately, this pressure dependence is predictable and can be corrected for in cases where it has an impact on accuracy (typically only significant for pressures in excess of 100 psig). The graph shown in Figure 3-1 shows the expected span shift as a function of pressure for nitrogen.
Example: To first determine and then change the active gas record using RS-232, Computer transmits: {S6} HFM flow meter replies: {0} This indicates that gas record #0 is currently active. Computer transmits: {S6=4} This changes the active gas record to #4. See the Software Manual for further information including how to setup a new gas record and how to reconfigure an existing gas record. CAUTION Accessing the rotary encoder requires removing the enclosure front plate.

WARRANTY 5. Warranty 5.1. Warranty Repair Policy Hastings Instruments warrants this product for a period of one year from the date of shipment to be free from defects in material and workmanship. This warranty does not apply to defects or failures resulting from unauthorized modification, misuse or mishandling of the product. This warranty does not apply to batteries or other expendable parts, nor to damage caused by leaking batteries or any similar occurrence.
Appendices 6. Appendices 6.1. Appendix 1- Volumetric versus Mass Flow Mass flow measures just what it says, the mass or weight of the gas flowing through the instrument. Mass flow (or weight per unit time) units are given in pounds per hour (lb/hour), kilograms per sec (kg/sec) etc. When your specifications state units of flow to be in mass units, there is no reason to reference a temperature or pressure. Mass does not change based on temperature or pressure.
the units are called standard liters per minute (SLM) or standard cubic feet per minute (SCFM), etc because it is referenced to a standard temperature and pressure when the volume is calculated. 6.2. Appendix 2 - Gas Conversion Factors The gas correction factors (GCF’s) presented in this manual were obtained by one of four methods.
For example, to get a desired flow of 20 sccm of argon flowing through the meter, divide 20 sccm by 1.3978 20.000 / 1.3978 = 14.308 That is, you ` (adjust the gas flow) to read 14.308 sccm. Some meters, specifically the high flow meters, are calibrated in air. The flow readings must then be corrected twice. Convert once from air to nitrogen, then from nitrogen to the gas that will be measured with the meter.
