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.

2. 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.
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 HFMI-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.
There are two possible connection methods to the analog terminal strip. The standard method is by inserting a cable through the supplied cable gland with an external jacket that meets the specifications of the following caution note and tightening down the cable gland nut securely to seal against the cable jacket. There is also an optional sealed circular connector that may be ordered with the instrument.
the range of 5-28 Vdc from a source external to the flow meter. The loop supply can be the same supply as that for the instrument power or it can be an isolated loop supply. Figure 2-3 shows a typical setup using the same supply. This method requires a jumper from pin 2 to pin 4 on the terminal strip while connecting pin 3 to a wire that carries this signal to the indicator (for example, a process ammeter, data acquisition system, or PLC board).

2.1.1.2. 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.
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. RS-485 If RS485 is specified on the order, the flow meter is set to the default values: address 61, unterminated Tx and Rx lines. While the default address is 61, all instruments will respond to an address of FF.
Since the alarms act as switches they do not produce a voltage or current signal. However, they can be used to generate a voltage signal on an Alarm Out line. This is done by connecting a suitable pull-up resistor between an external voltage supply and the desired alarm line while connecting Alarm Common to the common of the power supply. When activated, the alarm line voltage will be pulled toward the alarm common line generating a sudden drop in the signal line voltage.
2.2. Rotary Gas Selector The Hastings 400 Series flow meters can have up to eight different calibrations stored internally. These are referred to as gas records. These records are used to select different gases, but they can also be useful in other ways; for instance reporting the flow in an alternate range, flow unit or reference temperature. The records are referred to by their number label from #0 – #7. The first six records will, by default, be setup for most common six gases as shown in Figure 2-11.
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. When set to a number position from 0 to 7 it activates the corresponding gas record. If a number greater than 7 is selected, then gas record control is passed to software. Software: See Section 3.

3. 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 RS485). 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.
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. When commanded, the meter initiates an internal routine that performs the following sequence: measure the current flow reading, store it in nonvolatile memory as a zero offset, and remove this value from all subsequent readings.
Flow meter Output Indicated Flow (% Full Scale) 250% 200% 150% 100% Analog Output Digital Output 50% 0% 0% 100% 200% 300% 400% 500% 600% Flow (% Full Scale) 3.4.2.3.6. Reverse Flow 3.7. High Pressure Operation When operating at high pressure, the meter’s performance can be affected in two distinct and separate ways—a zero shift and a span (calibration) shift.
3.7.1. Zero Shift The zero offset can occur as the result of natural convection flow through the sensor tube if the instrument is not mounted in a level orientation with flow horizontal. This natural convection effect causes a zero shift proportional to the system pressure. The overall effect is more pronounced for gases with higher density. Normally the shift is within the allowable zero offset range and can be removed by activating the zero reset at the operating pressure. 3.7.2.
CAUTION NOTE 3.10. Accessing the rotary encoder requires 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. The software command to change the active gas record will not be executed unless the rotary encoder is set to a number greater than 7.

5. 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.
6. 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.
6.2. Appendix 2 - Gas Conversion Factors The gas correction factors (GCF’s) presented in this manual were obtained by one of four methods. The following table summarizes the different methods for determining GCF’s and will help identify for which gases the highest degree of accuracy may be achieved when applying a correction factor. 1. Empirically determined 2. Calculated from virial coefficients of other investigator’s empirical data 3. From NIST tables 4.
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. In this case, multiply the reading times the ratio of the process gas’ GCF to the GCF of the calibration gas. Example: A meter calibrated in air is being used to flow propane. The reading from the meter is multiplied by the GCF for propane and then divided by the GCF of air. 20 x (0.
