  • Page 8 DEFINITIONS USED IN THIS MANUAL The following terms are used frequently in this manual. They are presented here with their definitions for your information. Setpoint—The command or control signal supplied to a flow controller is called its setpoint. The controller will maintain the flow at this value. Full scale—The highest flow that an instrument will meter within its specified accuracy.
  • Page 9 THE CAPILLARY THERMAL OPERATING PRINCIPLE The operating principle of the SmartTrak instruments is based on heat transfer and the first law of thermodynamics. During operation process gas enters the instrument’s flow body and divides into two flow paths, one through the sensor tube, and the other through the laminar flow bypass.
  • Page 10 Figure 1-2. Flow Measuring Principle Figure 1-3. Sensor Temperature Distribution Figures 1-2 and 1-3 show the mass flow through the sensor tube as inversely proportional to the temperature difference of the coils. The coils are legs of a bridge circuit with an output voltage in direct proportion to the difference in the coils’...

  • Page 11: Chapter 2 Installation

    In the SmartTrak mass flow controllers, the gas which flows through the monitoring section is precisely regulated by the built-in electromagnetic valve. The normally closed valve is similar to an on/off solenoid valve, except that the current to the valve coil, and hence the magnetic field, is modulated so that the ferromagnetic valve armature, or valve plug, assumes the exact height above the valve’s orifice required to maintain the valve’s command flow (set point).

  • Page 12: Pre-Installation Check List

    Pre-Installation Check List 1. Double-check to be sure that the O-ring material used in your instrument is compatible with the gas to be measured. The O-ring material used in your SmartTrak can be found in the Data Label. See Appendix A for a table of elastomer compatibility with a wide variety of gases.

  • Page 13: Installing The Instrument-Plumbing

    7. The instrument has specific power supply requirements. See the table later in this chapter for a complete listing of power requirements. Installing the Instrument—Plumbing ® ® SmartTrak instruments are supplied with compression, VCO , VCR , or female NPT process connections.

  • Page 14: Vco Fittings

    VCO Fittings Position the instrument with the flow direction arrow pointing in the direction of flow. Tighten the nut finger-tight, and then 1/8 turn tighter with a wrench. Do not over- tighten! Check the system’s entire flow path thoroughly for leaks. Do not use liquid leak detectors.

  • Page 15: Installing Your Instrument-Mechanical Mounting

    Installing your Instrument—Mechanical Mounting Mounting your Instrument The base plate or bottom of the instrument has 4 mounting holes. Two are SAE thread and two are metric thread. For location and dimensions, please see Appendix A. Your SmartTrak instrument is made from premium 316 stainless steel. As a result, it may require substantial mounting brackets to properly support its weight.

If you are using the power supply supplied by Vögtlin, connect it to the 15-pin HD DB-15 connector on the side of the instrument.
  • Page 20 CAUTION: This instrument is not a loop-powered device! Do NOT apply power to the 0/4-20 mA output or input connections. Analog Output Signals:  Output Signal—Voltage: Measure the voltage output signal across the red (pin 2) wire and any of the analog grounds: brown (pin 1), orange (pin 3) or gray (pin 10). The minimum load is 1000 Ohms.

    CHAPTER 3: ANALOG OPERATION Your SmartTrak instrument may be operated in three different ways: THREE CONTROL OPTIONS A. Analog Input/Output Operation (This Chapter): Using analog input/output signals at the 15-pin mini-D connector. B. Digital Operation with Pilot Module (Chapter 4): Using the optional Pilot Module. C.

    Analog Operation, Mass Flow Controller After your instrument is installed and the system has undergone a complete leak check as discussed in detail in Chapter 2, follow these steps: 1. The valve will remain closed until power is supplied. See Chapter 2 for wiring instructions.

  • Page 24: Smarttrak Features

    SmartTrak Features Setpoint Adjustment The setpoint (command) input signal you supply to SmartTrak must be a direct linear representation of 0% to 100% of the mass flow full-scale value. Apply the setpoint signal from pin 8 to any of the analog grounds (see Chapter 2 for wiring details). A setpoint value of 0 VDC or mA (or 1 VDC or 4 mA) will regulate the flow to 0% and a setpoint value of 5.00 VDC (or 10 VDC or 20 mA) will adjust the flow to 100% of the instrument’s full scale range.

  • Page 56 Proceed to the next section. If the screen appears, but the yellow and white boxes are all empty, you have selected the wrong “Com Port number.” See the section titled “Com Port” on page 5-16 for instructions on how to change the communication port number. If the screen appears, but only the Mass Flow box shows a value, you are using the correct Com Port, but your computer is not talking to the SmartTrak.

  • Page 67 The instrument’s maximum flow rate is also recorded on the data label (at the back of the instrument) and on the calibration certificate. You may select any full-scale value between 100% and 50% of the maximum full-scale value. If you select a new full-scale value, it will re-define the analog outputs of the instrument.
  • Page 68 Here are some guidelines to remember if you choose to modify the Full Scale Value: Changing the full-scale value of the instrument does not affect the accuracy of the measurement. Instrument accuracy is a percentage of the original factory full-scale value If you enter a full-scale value beyond the instrument’s calibrated maximum range, the SmartTrak will automatically modify the full-scale to equal the factory full-scale value.

If meter is in streaming mode, this data will stream until a FLOWwSETPOINT, FLOWwSETPOINTwDAC or TOTALwDIFFwDAC is sent to the meter. If not in streaming mode then one flow will be return with each FLOW command sent.
