Lo-Flo Flowmeter (0-3.5 L/min range)
Flow rate
0.5 L/min
1 L/min
3 L/min

Equipment Setup

Connect the Pressure Compensated Flowmeter inlet adapter to an appropriate
oxygen or air gas supply depending on model, at 4 Bar (60 Psig), 3.4 Bar (50
Psig) or 5 Bar (72.5 psig), as shown on the label. The 0 - 15 L/min flowmeter is
factory calibrated to be accurate to ± .25 L/min or ± 10% of reading (whichever
is greater) at 70°F (21°C) and 4 bar supply pressure. The Lo-Flo 3.5 model is
calibrated to be accurate to ± .125 L/min between 0.25 and 3.5 L/min.
CAUTION ⚠: Operating flowmeters at extreme temperatures (approaching 0
Ensure the flowmeter is securely attached to or locked into the gas outlet. The
flowmeter must be positioned vertically to ensure maximum accuracy.
Setting the Flow Rate
2
1. Rotate the flow control knob counter-
clockwise to increase flow or clockwise
to decrease flow. Flow rate in liters
per minute is indicated by aligning
the CENTER of the ball with the scale
increments on the flowtube. Flow rates
on the Twin Pressure Compensated
Flowmeter are adjusted independently.
2. Flow rate may change with a change in
downstream resistance (backpressure at
the therapy device). This change may be
compensated for, without accuracy loss,
by re-adjusting the flow rate.

Pre-Use Checkout Procedure

The Pre-Use Checkout Procedure must be performed before using this
equipment on each patient. DO NOT connect the flowmeter to the therapy
device until this procedure is completed. All tests must be performed with the
appropriate gas supply depending on model. There should be no leaks.
