Chapter 2 Setting-Up Supplying Power The flowmeter can be powered in one of two ways: through the power jack using the supplied AC adapter or through the mini-DIN connector. The DC power input connector is shown below along with the power requirements. Power Supply: 7.5 VDC ±...
Connecting Filter and Flow Tubes The Models 4040/4043/4045 have an exposed thermal flow sensor, which must be protected from foreign matter and particles in the gas flow. TSI has supplied a filter, which should be connected to the inlet of the flowmeter; however, any filter will work as long as it has a minimum efficiency of 99.9%.
Configuration Software TSI has several software utilities to help you communicate with your flowmeter to change parameters and to obtain flow data. You can download the latest versions of these at no charge from our web site: 1. If you only want to change one or more of the operating parameters shown in Table 3 (above), the easiest way is to use the software utility called “TSI setup.”...
Recommended warm-up time of the flowmeter is 5 minutes. Flow Rate Measurement Flow rate data can be obtained from the Models 4040/4043/4045 through the LCD display, RS232 serial port or the linearized analog output. The analog output is a 0 to 10 volt DC linear signal representing 0 to 300 Std L/min (Model 4043: 200 Std.
LCD display and are available through the RS232 serial port. Volume Measurement The Models 4040/4043/4045 measure total volume by integrating flow over time. This is a calculated measurement performed by the flowmeter and is only available using the RS232 serial port. Volume is not displayed on the LCD display.
Re-certification To maintain a high degree of confidence in the measurements made by the Models 4040/4043/4045, TSI recommends that you return the instrument to TSI every 12 months for re-certification. For a nominal fee, we will recalibrate the unit and return it to you with a certificate of calibration and US National Institute of Standards Technology (NIST) traceability.
Chapter 5 Troubleshooting Table 4 lists the symptoms, possible causes, and recommended solutions for common problems encountered with the flowmeter. If the symptom is not listed, or if none of the solutions solves the problem, please contact TSI Customer Support at 1-800-874-2811 or 651-490-2811.

Volumetric flow rate is the true volume flow of the gas exiting the flowmeter. In some instances, volumetric flow rate rather than standard flow rate may be of interest. To display volumetric flow rate, the Models 4040/4043/4045 will multiply the standard flow measurement by the following density correction factor: ...
