5 – Installation and set-up MultiExact Gas Analyser
5.12 Setting up the flow alarm (option)
The flow alarm (utilising Flowcube [F
3
] technology) option measures the sample flow
through a measurement transducer and allows the user to configure two low flow
alarms and one high flow alarm. The flow alarm allows preventative maintenance to
be taken before the sample flow rate reduces to unacceptable levels
(see Section 2.4).
The configuration options and defaults for each flow alarm are given below:

In environments where significant ambient temperature changes are
expected, it is important to consider the temperature coefficient of the flow
alarm (page 128) when setting alarm levels.
☞
A zero and Normal calibration must be performed on the flow alarm before the
reading is accurate. See Section 6.4 for the calibration procedure.
☞
During measurement calibration or validation (not flow calibration) the status
level of each flow alarm will be demoted. A Fault status will be reported as a
Maintenance Required and a maintenance required status will not be reported
at all.
