Error of the flow measure
EN
No flow
An FE alert can be displayed incorrectly if the flow head control is set to low flow (1-2 l/min
typically) and the ambient temperature increase rapidly in the same time.
Device outside operational temperature
5.1.3. BLUETOOTH
E-GAUGE is equipped with a Bluetooth module for wireless data communication in the licence-
free zone of 2,4 to 2,5 GHz. Bluetooth communication is mainly used for primary calibration of
the pressure sensor and the flow head sensor and for setting up of the configuration of the gas
cylinder size and type of the control flow head during assembly of the valve to the gas cylinder.
Operational frequency: 2,4 GHz ISM zone (zone for radio transmitting in industrial, academic
and medical field)
Effective radiation power: max. 3 dBm
• A warning is indicated when there is a defect of the low
head sensor, its disconnecting or if the flow control head
is outside the defined position (e.g. in between two flows).
• Only the pressure value is indicated.
• The warning symbol FS (flow sensor) is indicated.
• Discontinue the cylinder from service immediately and
send it back to the owner of the filling station. Service
must be performed by a GCE certified service centre.
• A warning is indicated if the selected position of the
control flow head is > 1 l/min but simultaneously no
decrease in the cylinder gas pressure is reported (e.g.
closed shut-off valve or throttled outlet hose)
• The evaluation time depends on the set flow and the
cylinder volume, typically 2-10 minutes.
• Only the pressure parameter is indicated.
• The warning symbol FE (flow error) is indicated.
• Check if the shut-off valve is open or if the hose is not
throttled. Perform necessary actions. If the indication
does not disappear within few minutes, discontinue the
cylinder from service.
• Evaluation of FE alert is blocked for flows under 1 l/min.
• The FE symbol can be hidden by switching of the flow
control head to different position.
• A warning is indicated in case the valve is moved to a
room with temperature outside the allowed range of
operational temperature, see chapter 3.
• Only the pressure parameter is indicated.
• The warning symbol TC (thermal conditions) is indicated.
• If you want the Medivital®E to be operational, it must be
moved to a room which complies with the requirements
for allowed range of operation temperature (see chpt. 3).
