    POWER AND SIGNAL CONNECTIONS Power can be supplied to your controller through either the power jack (power jack not available on CSA/ATEX approved devices) or the 8 pin Mini-DIN connector. An AC to DC adapter which converts line AC power to DC voltage and current as specified below is required to use the power jack.

  • Page 33: Sending A Simple Script File To Hyperterminal

    Sending a Simple Script File to HyperTerminal® It is sometimes desirable to capture data for an extended period of time. Standard streaming mode information is useful for short term events, however, when capturing data for an extended period of time, the amount of data and thus the file size can become too large very quickly.
  • Page 34 14. The “Line Delay” box is defaulted to 0 milliseconds. This is where you will tell the program how often to read a line from the script file you’ve created. 1000 milliseconds is one second, so if you want a line of data every 30 seconds, you would enter 30000 into the box.

  • Page 35: Operating Principle

    Operating Principle All M Series Gas Flow Meters (and MC Series Gas Flow Controllers) are based on the accurate measurement of volumetric flow. The volumetric flow rate is determined by creating a pressure drop across a unique internal restriction, known as a Laminar Flow Element (LFE), and measuring differential pressure across it.

  • Page 36: Other Gases

    Other Gases: M Series Flow Meters can easily be used to measure the flow rate of gases other than those listed as long as “non-corrosive” gas compatibility is observed. For ex- ample, a flow meter that has been set for air can be used to measure the flow of argon. The conversion factor needed for measuring the flow of different gases is linear and is simply determined by the ratio of the absolute viscosity of the gases.

  • Page 37: Volumetric Flow And Mass Flow Conversion

    Once the corrected mass flow rate at standard conditions has been determined and the density at standard conditions is known (see the density table at the back of this manual), a true mass flow can be calculated as detailed in the following example: Mass Flow Meter Reading = 250 SCCM (Standard Cubic Centimeters/Minute) Gas: Helium Gas Density at 25C and 14.696 PSIA = .16353 grams/Liter...
