Page 6: Operation
OPERATION FlowStream flowmeters accurately measure the mass flow rate of most gases. The flow rate is determined by measuring the pressure drop across a unique internal restriction, known as Laminar Flow Element (LFE). The restriction is designed such that the gas molecules are forced into moving in parallel paths along the entire length of the passage for the entire range of operation of the device. -
Page 7: Reference Conditions For Mass Flow Measurement
Since the temperature sensor is embedded inside the sensor block, if ambient temperature is different from gas temperature, there would be a discrepancy between what the sensor reads and the true gas temperature. The flowmeter body would track ambient temperature while gas temperature would heat/cool the body at a different rate. -
Page 8: Battery Operation
BATTERY OPERATION The flowmeter includes an internal 800 mAh Lithium-Polymer battery that allows for 40 hours of continuous operation. The battery can be charged from any USB charger, and it typically takes 2 hours for a full charge when using a 1-Amp charger. When the meter is plugged into a PC for data logging, the battery will continue to charge through the USB port. -

KEYPAD OPTIONS UP: Pressing and holding the UP button for 5 seconds will take you into the data Upload mode (refer to USB data upload mode). UP: Consecutive (short) button press cycles between the following information on top of the display. -
Page 11: User Menu
CHG: Pressing CHG once shows the user menu. Once the desired menu item is selected, you can do one of the following: To change the set points Press SET to choose the particular menu item. Consecutive pressing of SET will cycle through the different digits of the set point. ... -
Page 12: Flow Lo
FLOW LO: Low set point for flow alarm. Range is 0 to FLOW HI – 2% FS. If set to 0, alarm is disabled. Alarm hysteresis is 1% FS. Use SET, UP, DOWN buttons as explained above to change the set point. LOG I: Time interval between data samples logged to USB memory stick. -
Page 13: Avg
AVG: Moving average array size. Use SET, UP, DOWN buttons as explained above to change the set point. This is the number of samples that are averaged when calculating the flow. Range is 1-100. Samples are added to the internal moving average array and a new output is displayed once every 100 msec. -
Page 14: Reset
RESET: Reset the parameters back to the original factory settings. Hold the SET button until the letters RESET will be displayed on the LCD one by one. This will provide a 5 second delay that is intended to prevent and accidental reset. - Page 15 Gas number: 1 Byte Gas Name Number Argon Carbon Dioxide Helium Hydrogen Methane Nitrogen Oxygen User Factor Flow: 2 Bytes Flow in SCFH or SLPM transmitted as Flow x 10 (depends on the units selected on the LCD) ...
