    Configuration Software ® has several software utilities to help you communicate with your flow meter to change parameters and to obtain flow data. You can download the latest versions of these at no charge from our web site: https://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.”...

    Recommended warm-up time of the flow meter 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.

  • Page 16: Temperature Measurement

    This is a calculated measurement performed by the flow meter and is only available using the RS232 serial port. Volume is not displayed on the LCD display. Refer to the Models 4040/4043/4045 RS232 Serial Command Set manual for instructions on using the volume function.

  • Page 17: Maintenance

    Never run liquids through the flow meter and never touch the sensor with a brush. Dust or other deposits on the flow sensor will degrade the 4040/4043/4045 flow meter’s flow accuracy. C A U T I O N The flow meter must be switched off for cleaning.

    Volumetric flow rate is the true volume flow of the gas exiting the flow meter. 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:  ...

This feature has programmable options that can improve its use accuracy.

  • Page 30: Considerations When Needing To Read Zero And Low Flow Accurately

    Considerations When Needing to Read Zero and Low Flow Accurately If the application requires accurate flow measurement at or near zero flows then it is recommended that the zero flow voltage be changed from its factory default of 0 volts to 100 mV. This is due to a slight offset of the ground voltage that could be interpreted as a low-level flow.

  • Page 31: Considerations For Setting The Span Flow Voltage

    Considerations for Setting the Span Flow Voltage If the application does not require the flow meter to read up to its span flow then it is recommended that the analog span be set to the maximum limit that is required by the application.
