2 / 16 page F L O W B O D Y F E A T U R E S • 1⁄2" to 4" pipe sizes • NPT threads available up to 2" in size • Stainless steel and carbon steel (with stainless steel sensor) construction • Flange connections for all sizes • Optional stainless steel flow conditioning plate for 1.5" and higher • Flow conditioning for 1⁄2" to 1" based on upstream length and sensor design A D D I T I O N A L F E A T U R E S T O T A L I Z E R Two 7-digit flow totalizers, one resettable and one non-resettable are provided. Flow units selectable in user’s choice of engineering units. Totalizer data is electronically stored eliminating the need for backup batteries and provides maximum safeguard data in the event of a power interruption. The total- izer can be reset using the display module, HART or via PACTware™. T E M P E R A T U R E C O M P E N S A T I O N Thermal flow technology measures the mass flow rate without the need for pressure and temperature correction as required with most gas flow instru- ments that measure the flow rate at actual condi- tions. However, changing temperature will change the properties of the gas which effect convective heat transfer. The Model TA2 measures the gas temperature and automatically adjusts the mass flow measurement for changes in gas properties over the entire temperature range of the instrument. D I A G N O S T I C S Diagnostics is an important aspect of the TA2. The Enhanced TA2 has additional diagnostics to check the operation and performance of the unit. Diagnostics includes probe status, a test of RTD drift with automatic recalibration, and overall performance. In order to verify that the calibration and configura- tion match the original calibration conditions, the user can select a specific signal and compare the TA2 display value against the original calibration certificate. L O W V O L T A G E O P E R A T I O N The TA2 will accept input power as low as 11.6 VDC on Explosion Proof units when used with Integral Electronics. S E L E C T A B L E S T P C O N D I T I O N S The TA2 directly measures mass flow of the gas referenced to Standard Temperature and Pressure (STP) conditions. Software permits the user to change STP conditions for their own requirements. A R E A C O M P E N S A T I O N F O R P I P E S I Z E The TA2 automatically compensates the flow mea- surement based on actual area of the pipe. The user simply enters the size or the area of the new pipe, and the instrument automatically calculates the flow including factors for the probe blockage. H A R T C O M M U N I C A T I O N Using HART/AMS communication, the user can configure the instrument from a remote location. HART provides the same functionality as the display module interface including all configuration and diagnostic information. A I R E Q U I V A L E N C Y Using historic air-gas calibration data, an air equiva- lency calibration can be performed on select gases. Consult Magnetrol® for details and flow ranges. 2 |
