OperationThe Q200 is a fluidic oscillator type, cold water meter. Water enters
the fluidic oscillator through a nozzle that creates a jet. When the
jet enters the flow chamber, it will initially be drawn to one of the two
diffuser walls and will travel along the wall through the principle of
the Coandã effect and then exit the flow chamber. Due to the local
pressure being lower by the opposite diffuser wall, the jet will move
towards the other wall and therefore starts to oscillate between
one diffuser wall and the other. Carefully optimized features within
the flow chamber provide oscillation across a greater flow range.
This oscillation between the diffuser walls continues while flow is present
where each oscillation represents a precise volume that has passed
through the meter. The oscillation is monitored by electrodes placed
next to each diffuser wall, in which an electrical current is induced in
the jet by a pair of powerful permanent magnets. Sensing electronics
capture when the oscillations occur and totalize the volume passed
displaying the registered volume on a liquid crystal display. When no
fluid present i.e. air, no signal is present and no volume measured.
ApplicationThe meter is for use only with potable cold water
up to 50 °C (122F) and an overload pressure
up to 20 bar (290 PSI). The meter will register
between 98% and 102% accurate throughout
the normal operating range and between 95%
and 105% at the low flow for accuracy class
2, T30 temperature class meters, as stated
within OIML R49-1:2006. No adjustment
is required before or after installation and
the in-service accuracy errors can be up
to twice that of the rated accuracy class.

REGISTERThe register is contained within an advanced engineered polymer enclosure which is completely potted to eliminate air and any potential condensation. To assure easy reading, the totalizer LCD digits are large and the dial face is colour coded to identify billing units and verification units. The applicable flow range, type approval and registration units are printed on the dial face. The 10 digit LCD includes a low-flow indicator that provides visual indication of a perceived water leak. The register contains a removable Lithium Thionyl Chloride battery pack that has a typical 15 year battery life under normal operating conditions.
READING THE METERThe reading is displayed on the electronic register of the meter under the protective lid.
Cubic MetreThe display digits before the decimal point, surrounded by a black border, represent the standard billing units in whole cubic metres (m3) and the digits after the decimal point, surrounded by a red border represent fractions of a cubic metre.

When water is flowing, a flashing square icon appears to the lower right of the display, but when the flow has stopped this indicator will be extinguished. To read the meter using a remote reading system, refer to the manufacturer’s instructions.
CONSTRUCTIONThe construction of the Q200 meters comply with the requirements of the OIML R49-1: 2006 and WRAS specifications. The meter consists of a combined single piece polymer main case with threaded ends and fluidic oscillator measuring chamber with no moving parts, and an electronic register assembly that is attached onto the measuring chamber.
The measuring chamber is moulded from first grade PPS and has raised characters designating model, size and direction of flow. The fluidic oscillator measuring chamber uses patented magnet sensing with inset moulded sensor electrodes to monitor flow.
The Q200 meter can be optionally fitted with brass thread sleeves bonded to the polymer threads.
AMR/AMI CONNECTIVITYThe Q200 meter is supplied AMR ready with an integral communication cable that is factory set to support one of the following output modes:
• Encoder output that uses standard ASCII serial protocols
• Pulse output with default setting 1 pulse per litre
Suitable connector cable options can be supplied for connection to Elster compatible devices.
