Instruction Manual Smart-Trak® 50 Series 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 the setpoint. The controller will maintain the flow at this value. Full scale—The highest flow that an instrument will measure within its specified accuracy.
Instruction Manual Smart-Trak® 50 Series The Smart-Trak® 50 Series Flow Sensing Principle The operating principle of the Smart-Trak® 50 Series instruments is based upon 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.
Instruction Manual Smart-Trak® 50 Series 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’ resistance; the result is the temperature difference (∆T). Two other parameters, heat input (H) and coefficient of specific heat (Cp) are both constant.
Instruction Manual Smart-Trak® 50 Series Chapter 2: Installation Before You Begin Installation Warning! Injury can result if line pressure exceeds the maximum rating of 145 psig (10 barg). Before installing the instrument, ensure that the installation site conforms to the specific operating parameters recorded on the instrument’s Data Label. The Data Label is located on the back of the instrument electronics enclosure.
Instruction Manual Smart-Trak® 50 Series 5. Output Signals: The 50 Series has RS-232 communications as the standard configuration, with optional RS-485, 0-5 VDC or 4-20 mA. The output signals specified at time of order will be indicated on the data label. 6. The instrument has specific power supply requirements.

Instruction Manual Smart-Trak® 50 Series VCO Fittings 1. 2. 3. 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 overtighten! Check the system’s entire flow path thoroughly for leaks. Do not use liquid leak detectors on or near the unit. Exposing the instrument to leak detector fluid may cause damage. VCR Fittings 1. 2. 3. 4.
Instruction Manual Smart-Trak® 50 Series Installing Your Instrument—Mechanical Mounting Mounting Your Instrument The base plate or bottom of the instrument has four mounting holes. Two are SAE thread and two are metric thread. For location and dimensions, please see Appendix B. Installing Your Instrument—Electrical Connections All electrical connections for your Smart-Trak® 50 Series instrument can be made on either side panel.
Instruction Manual Smart-Trak® 50 Series Instrument Power: The Smart-Trak® 50 Series requires a 24 VDC power supply (meter can use 15 VDC). Connect power to the 9-pin connector on the side of the instrument (pins 5 and 6). If you are supplying your own power source, it must regulate 24 VDC, and supply at least 315 mA (445mA for RS-485 controller) (meter can use 15 VDC, 85 mA) (215mA for RS-485 Meter). The instrument is polarity sensitive.
Instruction Manual Smart-Trak® 50 Series do not have a serial port, use a serial to USB convertor (available at most consumer electronics stores or from Sierra). To minimize the potential for RF interference, it is recommended to shield these wires. If you are making your own cabling, Sierra recommends you use wire that comes shielded. Solder one end of the shield wire/casing to the DB-9 connector at one end of the wire, so as to allow the collected interference to dump to earth ground.
Instruction Manual Smart-Trak® 50 Series Chapter 3: Digital Operation Mass Flow Meter After your instrument is installed and the system has undergone a complete leak check as discussed in detail in Chapter 2, follow these steps: ® The Smart-Trak 50 Series is not a loop-powered device.

Instruction Manual Smart-Trak® 50 Series 3. Adjust the controller setpoint to the desired flow rate by supplying an appropriate signal (mA, voltage or digital). The effective control range of the unit is 5% to 100% of the calibrated full scale flow range. Automatic shut-off occurs at 4.9% of the factory full scale calibrated range unless specifically modified at time of order.
Instruction Manual Smart-Trak® 50 Series 50 Series Features Setpoint Adjustment The setpoint (command) input signal you supply to the 50 Series must be a direct linear representation of 0% to 100% of the mass flow full scale value. Apply the setpoint signal per Chapter 2. A setpoint value of 0 VDC or 4 mA will regulate the flow to 0% and a setpoint value of 5 VDC or 20 mA will adjust the flow to 100% of the instrument’s full scale range.
Instruction Manual Smart-Trak® 50 Series Over-Range Condition If the mass flow rate exceeds the full scale range listed on the Smart-Trak® 50 Series data label the output signal will measure above full-scale. However, the device has not been calibrated for flows in excess of the calibrated full scale value and the value will be both non-linear and inaccurate if an over-range condition exists. Please be aware that the analog outputs can exceed full scale by as much as 20%, or more.
