Implementing Measures for Advanced
Notice of Water Flow Concerns
The rare presence of unwanted water flow from an automated watering system can be
detrimental to animal welfare and research. Atypical mouse behavior such as packing
bedding in a drinking valve or pushing an enrichment device against the valve stem
can lead to an undesirable discharge of water.
Advanced notice of water flow concerns will allow vivarium staff the ability to intercept unwanted flow before it becomes a problem. FloSense™ monitors water flow at
an individual mouse rack and alarms if there is a constant flow of 0.5 ml per minute
or greater detected. In fact, FloSense is so acutely sensitive that it comes equipped
with a settable alarm delay to accommodate the normal drinking activity of mouse
populations. The operant principle is, the faster the flow of water, the faster FloSense
responds with an alarm. Depending on the speed of flow, FloSense can be triggered to
alarm in as little as 10 minutes.
If abnormal flow is present, a red LED illuminates on the FloSense unit as a visual
indicator of the condition. At the same time, an alarm is sent to the Edstrom Watchdog®, Pulse®, or a building automation system to be delivered to staff through call out,
e-mail, or page. The monitoring system can also log when the event began, when the
alarm was acknowledged, and when the flow condition was resolved.
FloSense is universally compatible with all makes and models of cage racks. It
employs quick disconnect coupling to interface with the automated watering system
of the cage rack. This allows FloSense to be retrofitted with existing Edstrom flushing
automated watering systems.
An optional solenoid can be added as an additional safety measure. In the event
there is an alarm, the normally open solenoid will close off the water supplied to the
individual rack the FloSense is connected to. Simply pressing the reset button on the
FloSense will open the solenoid and start the water flowing again.
The ergonomic and labor saving benefits of using automated watering systems in
the vivarium have been known for years. Now the Edstrom FloSense magnifies that
value by presenting contingency preparedness. Whether there is a need for safeguarding an irreplaceable strain, or the desire to have an additional layer of protection for
