Flow monitoring
16.2.1
Input terminal blocks for
flow monitoring
While PoolManager
®
offers two separate inputs for flow monitoring:
16.2.1.1
Measurement water monitoring (standard)
Measurement water flow is usually monitored with an inductive
proximity switch integrated into the measurement chamber. Flowing
water raises the float in the measurement chamber. If the float rises to
the level of the proximity switch, then the latter will supply the flow
signal.
Inductive proximity switch (left)
and float (right)
The proximity switch has three connection lines and is connected to
PoolManager
®
terminal block [2] (
Flow
). The flow signal is ALWAYS
monitored; this monitoring cannot be deactivated for safety reasons.
16.2.1.2
Circulation monitoring (optional)
Optionally, an additional signal can be used to monitor the circulation
circuit.. Doing so usually entails pressure sw

HAZARD!
Gaseous chlorine produced from dosing in
standing water via unreliable flow monitoring.
If only one single sensor on input
flow monitoring, then there is risk for dosage in
standing water in the event of an error. Poisonous
chlorine gas can be yielded when ChloriLiquid and pH
minus come together.
Potential consequence: Death or the gravest
degree of injury,
heavy material damage.

‘PoolManager

offers two different options for handling a missing flow
signal:
16.2.2.1
No alarm for missing flow signal
(Default, flow alarm acknowledgement = automatic)
In this option, PoolManager
®
does not assess a missing flow signal as
an error, but rather as a normal operating state. For most swimming
pools, circulation only runs in intervals and not around the clock. In
this case, it is entirely normal for PoolManager
signal in times without circulation.
Accordingly, PoolManager
®
signalises the missing flow signal only as
a normal operating status, not as an alarm status. The special
