10. PRINCIPLES OF OPERATION 10.1. BASIC PRINCIPLES OF DYNAMIC DILUTION CALIBRATION The T700 Dynamic Dilution Calibrator generates calibration gas mixtures by mixing bottled source gases of known concentrations with a diluent gas (zero air).
Principles of Operation Teledyne API – Model T700 Dynamic Dilution Calibrator This dilution process is dynamic. The T700’s CPU not only keeps track of the temperature and pressure of the various gases, but also receives data on actual flow rates of the various MFCs in real time so the flow rate control can be constantly adjusted to maintain a stable output concentration. The T700 calibrator’s level of control is so precise that bottles of mixed gases can be used as source gas.
Teledyne API – Model T700 Dynamic Dilution Calibrator Principles of Operation 10.1.1. GAS PHASE TITRATION MIXTURES FOR O3 AND NO2 Because ozone is a very reactive and therefore under normal ambient conditions a shortlived gas, it cannot be reliably bottled, however, an optional O3 generator can be included in the T700 calibrator that allows the instrument to be use to create calibration mixtures that include O3.
Principles of Operation Teledyne API – Model T700 Dynamic Dilution Calibrator In this case, Totalflow is calculated as: Equation 10-4 DILflow = Totalflow- NO GASflow - O3flow WHERE: NOGASflow = NO source gas flow rate (For calibrator’s with multiple source gas MFC, NOGASflow is the sum of the flow rate for all of the active cal gas MFCs) Totalflow = total gas flow requirements of the system. O3 flow = the flow rate set for the O3 generator.
Teledyne API – Model T700 Dynamic Dilution Calibrator Principles of Operation 10.2.1. GAS FLOW CONTROL The precision of gas flow through the T700 Dynamic Dilution Calibrator is centrally critical to its ability to mix calibration gases accurately. This control is established in several ways. 10.2.1.1. Diluent and Source Gas Flow Control Diluent and source gas flow in the T700 calibrator is a directly and dynamically controlled buy using highly accurate Mass Flow Controller.
Principles of Operation Teledyne API – Model T700 Dynamic Dilution Calibrator 10.2.1.2. Flow Control Assemblies for Optional O3 Components Whereas the gas flow rates for the final mixing of gases is controlled directly by the calibrator’s MFCS, under direction of the CPU, other gas flow rates in the calibrator are set by various flow control assemblies located in the gas stream(s).
Teledyne API – Model T700 Dynamic Dilution Calibrator Principles of Operation 10.2.1.3. Critical Flow Orifices The most important component of the flow control assemblies is the critical flow orifice. Critical flow orifices are a remarkably simple way to regulate stable gas flow rates. They operate without moving parts by taking advantage of the laws of fluid dynamics. By restricting the flow of gas though the orifice, a pressure differential is created.
Principles of Operation Teledyne API – Model T700 Dynamic Dilution Calibrator 10.2.2. INTERNAL GAS PRESSURE SENSORS The T700 includes a single pressure regulator. Depending upon how many and which options are installed in the T700 calibrator, there are between two and four pressure sensors installed as well.
