Both flow conduits are designed to ensure laminar flows and therefore the ratio of their flow rates is constant. Two precision temperature sensing windings on the sensor tube are heated, and when flow takes place, gas carries heat from the upstream to the downstream windings. The resultant temperature differential is proportional to the change in resistance of the sensor windings. A Wheatstone bridge design is used to monitor the temperature dependent resistance gradient on the sensor windings which is linearly proportional to the instantaneous rate of flow. The output of the Wheatstone bridge is converted to digital format with a 12 Bit ADC (analog to digital converter). An on-board microprocessor and nonvolatile memory store all calibration factors and directly control a proportionating electromagnetic valve. The digital closed loop control system continuously compares the mass flow output with the selected flow rate. Deviations from the set point are corrected by compensating valve adjustments, with PID algorithm thus maintaining the desired flow parameters with a high degree of accuracy. </p> <p><strong>Interface </strong> </p> <p>The digital interface operates access to applicable internal data including Flow Set Point, Actual Flow, Zero Adjustments, and linearization Table Adjustments. </p> <p><strong>Auto Zero </strong> </p> <p>The DFC automatically nulls the sensor zero offset whenever the flow set point is below 2% of full scale. To accommodate this feature the control valve must fully close under that condition. Provisions are made to either disable, force or store the current auto zero via digital commands. </p> <p><strong>Totalizer </strong> </p> <p>The firmware for the DFC provides functions to register total gas quantity. The total mass of gas is calculated by integrating the actual gas flow rate with respect to time. </p> <p>Digital interface commands are provided to: </p> <ul><li>Set the totalizer to Zero </li> <li>Start/Stop totalizing the flow </li> <li>Read the totalizer </li> <li>Start the totalizer at a preset flow </li> <li>Stop the flow at a preset total </li> </ul> <p><strong>Multi-Gas Calibration </strong> </p> <p>The DFC is capable of storing primary calibration data for up to 10 gases. This feature allows the same DFC to be calibrated for multiple gases while maintaining the rated accuracy on each. </p> <p><strong>Conversion Factors </strong> </p> <p>Conversion factors for up to 256 gases are stored in the DFC. Conversion factors may be applied to any of the ten gas calibrations via digital interface commands. </p> <p><strong>Flow Alarms </strong> </p> <p>High and Low gas flow Alarm limits are programed using the digital interface. Alarm conditions are reported via the digital interface or can activate the contact closure outputs. </p> <p><strong>Programmable Flow </strong> </p> <p>Aalborg software supports programmable flow modes, allowing execution of custom programming of up to ten steps. Various flow configurations include ramping, linearized increasing and decreasing modes. </p> <p><strong>Auto Tune </strong> </p> <p>The Auto Tune function allows the DFC to automatically optimize control response for the gas under actual process conditions. </p> <p><strong>Contact Closure </strong> </p> <p>Programmable via the digital interface such that the relays can be made to switch when a specified event occurs (e.g. when a low or high flow alarm limit is exceeded or when the totalizer reaches a specified value). </p> <p><strong>Valve Override </strong> </p> <p>Means are provided to force the control valve fully open (purge) or fully closed via either the analog or digital interfaces. </p> <p><strong>Self Diagnostics </strong> </p> <p>Whenever power is first applied, the DFC runs a series of Self Diagnostic Tests to ensure that it is in optimum working condition. </p> <p><strong>Engineering Units </strong> </p> <p>The flow set point, measured gas flow and associated totalizer data is scaled directly in engineering units via digital interface commands. The following units of measure are supported: % of FS, mL/min, mL/hr, SCFM, SCFH, sL/min, sL/hr, lbs/hr, lbs/min, and one user defined unit of measure. </p> <p><strong>Balanced Power Supply </strong> </p> <p>The DFC operates on ±15 VDC. The current requirements for the positive and negative power supplies are balanced such that the current in the power supply common connection is minimized. Maximum power consumption is 13.5 watts at ±15 VDC. </p>

Regardless of where you are, your Command Module is as close as the nearest browser! There are two levels of Ethernet based Remote Controls: HTML web server and TELNET. The HTML web server, which is hosted on the Command Module lets one view Current Flow Rate, Control Valve Mode and/or Set Point, Monitor Totalizer Reading for Selected Channel. The TELNET console provides complete control over all modes and functions and using the same Software interface commands set as the RS-232 communication interface. </p>

The remainder of the gas flows through the primary flow conduit. The geometry of the primary conduit and the sensor tube are designed to ensure laminar flow in each branch. According to principles of fluid dynamics, the flow rates of a gas in the two laminar flow conduits are proportional to one another. Therefore, the flow rates measured in the sensor tube are directly proportional to the total flow through the transducer. In order to sense the flow in the sensor tube, heat flux is introduced at two sections of the sensor tube by means of precision-wound heater sensor coils. Heat is transferred through the thin wall of the sensor tube to the gas flowing inside. As gas flow takes place, heat is carried by the gas stream from the upstream coil to the downstream coil windings. The resultant temperature dependent resistance differential is detected by the electronic control circuit. The measured temperature gradient at the sensor windings is linearly proportional to the instantaneous rate of flow taking place. An output signal is generated that is a function of the amount of heat carried by the gases to indicate mass molecular based flow rates. </p>
