Page 9: Setting-Up
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 ±... -
Page 10: Connecting Filter And Flow Tubes
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%. -
Page 11: Configuration Software
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: http://flowmeters.tsi.com 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.”... - Page 12 3. If you plan to develop a more sophisticated program for data collection and control using LabVIEW, you can download a demonstration program called “Real-time Demo Program” and the source code “Source Code for Real-time Demo Program.” This program is intended to be a basic demonstration program and not a practical laboratory tool.

Flowrate Measurement Flowrate 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. -
Page 14: Temperature Measurement
Pressure Measurement The Models 4040/4043/4045 measure absolute pressure near the outlet of the flowmeter in the SI units of kilo-Pascals (kPa). Pressure measurements are required when converting from standard to volumetric flow. Absolute pressure measurements are displayed on the LCD display and are available through the RS232 serial port. -
Page 15: Maintenance
Remove dust, particles and fibers from the sensor, with clean, dry compressed air. The flow sensor will break if touched. Never run liquids through the flowmeter and never touch the sensor with a brush. Dust or other deposits on the flow sensor will degrade the 4040/4043/4045’s flow accuracy. Caution The flowmeter must be switched off for cleaning. -
