Thermatel® Model TA1 Mass Flow Transmitter D E S C R I P T I O N Thermatel Thermal Mass Flow Transmitter, Model TA1, provides a high level of performance in mass flow measurement of air and gases. Powerful microprocessorbased electronics provides an instrument that is easy to set up and configure. The TA1 provides the highest level of accuracy, repeatability, and temperature compensation available.

The sensor contains two mass balanced elements with precision matched RTDs. The reference RTD measures the process temperature; the active RTD measures the temperature of the heated element. The temperature difference between the two RTDs is greatest at low flow and decreases in a non-linear relationship as the flow increases. The instrument accurately measures this temperature differential and converts it to a linear flow signal F L O W B O D Y with a 100-to-1 turndown. The microprocessor-based electronics provide the ability to configure the instrument for your exact process conditions, provide advanced diagnostics, plus advanced temperature compensation program to ensure accurate, repeatable flow measurement over the entire operating range of the instrument. The TA1 is available with either an insertion probe or flow body. F E A T U R E S • 1⁄2" to 4" pipe sizes • Flange connections for all sizes • NPT threads available up to 2" in size • Optional stainless steel flow conditioning plate for 1.5" and higher • Stainless steel and carbon steel (with stainless steel sensor) construction A D D I T I O N A L PROBE F E A T U R E S INSTALLATION Probes can be provided with a variety of process connections, including threads, flanges, or installation through a compression fitting. The sensor will fit pipe sizes of 11⁄2" diameter or larger (2" minimum with thread connection). The sensor is protected to prevent damage due to “bottoming-out” if inserted too far into a pipe. When using an insertion probe with compression fitting, the user can adjust the position of the sensor in the pipe to obtain the optimum location. Typically, this will be with the bottom of the probe 1.0" lower than the center line of the pipe. TOTALIZER The software totalizer provides an eight-digit display of the most significant numbers in the user’s choice of engineering units. If the totalized display exceeds eight digits, then the display changes to exponential notation. The use of EEPROM for storage of totalized data eliminates the need for backup batteries and provides maximum safeguard of data in the event of a power interruption. The totalizer can be reset via software. 2 • Flow conditioning for 1⁄2" to 1" based on upstream length and sensor design TEMPERATURE COMPENSATION Thermal flow technology measures the mass flow rate without the need for pressure and temperature correction. However, there is a need to temperature compensate the mass flow measurement for changes in gas properties due to variations in process temperature. By measuring the gas temperature, Model TA1 provides advanced temperature compensation to correct for changes in properties of the gas. The TA1 provides accurate flow measurement over the entire specified temperature range of the instrument. AREA COMPENSATION FOR PIPE SIZE Insertion of the sensor into a pipe reduces the flow area, thus increasing the velocity for a given flow rate. Magnetrol’s TA1 automatically compensates the flow measurement based on actual area of the pipe. The user simply enters the size or the area of the pipe, and the instrument automatically compensates the flow measurement. AIR EQUIVALENCY Using historic air-gas calibration data, an air equivalency calibration can be performed on select gases. Consult Magnetrol for details and flow ranges. A D D I T I O N A L F E A T U R E S TURNDOWN The TA1 offers excellent low flow sensitivity and high turndown ratios. The minimum detectable mass velocity is 25 SFPM. This provides high turndown ratios of over 100 to 1, depending upon the maximum flow rate. SELECTABLE STP CONDITIONS The TA1 directly measures mass flow of the gas at standard pressure and temperature (STP) conditions. Software permits the user to change STP conditions for their own requirements.

R E T R A C T A B L E H O T P R O B E A S S E M B L Y T A P Magnetrol offers two methods of removing the probe from the pipe without having to shut down the process. The Hot Tap Retractable Probe Assembly is designed to meet API (American Petroleum Institute) standards. The less demanding valve with compression fitting (part 0895218-001) will have some minor leakage when the probe is removed or re-inserted and does not have the safety cable to prevent “blow out” of the probe when removed under pressure. RPA requires a probe with 3⁄4" NPT process connection. The valve with compression fitting uses a 1" NPT connection while the RPA uses a 11⁄2" NPT connection.
