  • Page 12: Connecting Filter And Flow Tubes

    Connecting Filter and Flow Tubes The Model 4140/4143 has a thermal sensor exposed to the gas flow that must be protected from foreign matter and particles. TSI supplies a filter that 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%.

    Recommended warm-up time of the flowmeter is 5 minutes. Flow Rate Measurement Flow rate data can be obtained from the Model 4140/4143 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 20 Std L/min.

    Refer to the Series 4000/4100 RS232 Serial Command Set manual for instructions on how to select between flow units. The Model 4140/4143 has an independent temperature sensor in the flow tube to measure the gas temperature. The temperature sensor is used for temperature compensation of flow rate and for converting flow from standard to volumetric units.

  • Page 17: Maintenance

    Re-certification To maintain a high degree of confidence in the measurements made by the Model 4140/4143, TSI recommends that the instrument be returned to TSI every 12 months for re-certification. The flowmeter will be recalibrated and returned with a certificate of calibration to US National Institute of Standards Technology (NIST) traceable standards.
