Gray-Code detection system
Micro processor
The movement of the gas measuring unit is detected by a unique, High Frequent optical detection system, based on Gray-Code and 3 optical sensors on
the PCB. This system offers high resolution and a
tamperproof and failsafe detection, fit for instant flow
calculation and error curve correction.
Excellent accuracy

Final error code
The initial error curve of the diaphragm gas-meter is
introduced into the micro-processor in the index at 3
flows, Qmin, 0,2Qmax and Qmax.

With the High Frequency “Gray-Code” detection,
flow is calculated and by linear interpolation and
the error curve of the measuring unit corrected to
approx. 0.1%.

Temperature conversion (option)
Temperature conversion may be performed, for read out of base volume or energy.
A unique temperature measurement system ensures a precise measurement of temperature inside the
measuring unit, independent of the inlet gas temperature and the ambient temperature.
Correct measurement of gas temperature improves the accuracy with up to 3%.
Alarm log
Uniflo G4S electronic index has an auto diagnostic system, monitoring the conditions of the meter:
• Remaining life of battery (live calculation)
• Gas temperature, low and high limit*
• Temperature sensor error*
• High and high-high flow limit
• Gray-Code detection error
• Daily max. consumption error
• Self check error (hardware and software)
• Tamper detection (mechanical, magnetic)
30 latest errors will be recorded, along with time stamp.
*) Only for meter with temperature conversion

Tamper proof
Mechanical tampering of the index is not possible, as moving parts in the index are reduced to a minimum.
Removal of front cover will activate tamper alarm. The detection system is not sensitive for normal magnetic
fields. In case of extremely powerful magnets, a magnetic tamper alarm will be activated.
Communication is secured by encryption (AES compatible), with individual encryption keys, and by detection of invalid communication format, activating alarm.
Reverse gas flow will be stopped by mechanical lock in measuring unit, and reverse rotation will be detected by the “Gray-Code” and immediately activate an alarm. Also exceeding max. flow limit, or max. daily consumption limit will activate alarm. Alarms will be stored in the memory, with time stamp, to be transferred at
the next meter reading, or immediately, when radio is used. Alarms can be reset remotely.
Integrated valve (option)
The meter may be supplied with built-in valve, offering remotely closing of the gas-flow, after receiving
the signal at the meter reading.
Because opening of gas-valve might have important
safety impact (e.g. an opened unsecured gas-cooker), Flonidan has developed, both in hardware and
software, a dedicated procedure.
After the communication unit has given the signal
“open valve”, customer has to push a button on the
index to open the valve again. If the meter after
opening detects, within a given time frame, a too
high gas consumption, the valve will automatically
close again. Customer should first shut off gas consuming devices, before pushing the button again.
The time frame and max. gas consumption can be
configured on customer specifications (See diagram).
Command for safe opening without customer intervention is also available (See diagram).
