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. -

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 11: Flow Lo
When finished, keep holding the SET button down until “SAVED” is displayed, then release the SET button. FLOW LO: Low set point for flow alarm. Range is 0 to FLOW HI – 2% FS. If set to 0, alarm is disabled. -
Page 12: 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 13: 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 14: Available Flow Sizes
AVAILABLE FLOW SIZES Each size is offered in several optimized maximum flow rates as shown in the table below. These configurations provide the highest accuracy and turndown ratios stated in the specifications.
