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). The result is excellent resolution.
CHAPTER 2 INSTALLATION
Warning!
Before You Begin Installation
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 mounted
on the back of the instrument electronics enclosure (see sample Data Labels in Figure: 2-
1). This is critical because each instrument is configured for a specific application range.
Please review the gas or gases, the mounting orientation, the maximum flow range(s), the
inlet and outlet pressure(s), and the operating temperature(s). The line pressure should not
exceed 35 barg except for SmartTrak100 High Pressure version instruments (refer to
Injury can result if line
pressure exceeds the
maximum rating of
35 barg. for standard
SmartTrak 100.
Warning!
If installing a
SmartTrak 100 HP,
read Appendix E:
SmartTrak 100 High
Pressure Version
Safe Use before
installing instrument.
Warning!
Injury can result if line
pressure exceeds the
maximum rating of
345 barg when using
the SmartTrak 100
High Pressure.
Appendix D). The temperature should not exceed 50°C. The minimum operating
temperature is 0°C and ambient temperature is 0-50°C. If your application exceeds any of
these parameters, contact your Vögtlin Sales Agent before installation. You may also
contact one of Vögtlin’s Technical Support Centers.
