Flow Sensor Operation (optional)
The optional flow sensor notifies users of empty containers and/or upstream
occlusions. A handle cap accessory is available for storing the flow sensor when
not in use.
The flow sensor is not used for the first 25 ml delivered when changing from
secondary to primary. This is to account for overfill of secondary containers.
If a flow sensor is not connected to the pump, ensure protective plugs are installed
at the connector site to prevent entry of foreign material.
1. Plug a Model 180 Flow Sensor into applicable channel connector on back of
pump.
2. Attach flow sensor to upper portion of drip chamber.
3. Attach flow sensor to pump handle when not in use.
4. Routinely clean flow sensor with warm water while actuating slider, then dry
thoroughly.

•
Infusing fluids which form smaller drops, through a 60 drops/ml set, at high rates may result in a No
Upstream Flow Detected alarm. This is because the small, rapidly falling drops form a continuous
stream which does not trigger the flow sensor. In this event, unplug the flow sensor from the pump.
•
Do not use solvents or cleaning agents. Damage to plastic parts of the flow sensor could occur.
•
When using flow sensor, correct placement is essential for proper operation. Some infusion set drip
chambers have a flange at top to which flow sensor can be attached. Attachment on flange ensures
proper placement.
•
Upper surface of flow sensor should be slightly below drop-forming orifice but above level of fluid
in drip chamber.
•
Ensure drip chamber is at least 2/3 full and sensor optics are clean. Fluid level in drip chamber must
be checked/re–established after each empty container condition
•
When using flow sensor option while ambulating or transporting a patient from one area to
another, use care to avoid excessive swinging of solution container(s).
•
If the flow sensor option is in use, VTBI can be turned off by selecting VTBI, pressing CLEAR and then
ENTER keys or Primary VTBI can be deleted from the primary mode setup page.
