Water Meter Flostar Itron DN40 Designed to meet the advenced needs of water utilities in large revenue collection applications.
Engineered for reliability and built upon 20 years of industry-leading design, itrons Flostar M is the best choice for drinking water metering in commercial and industrial applications.
FEATURES AND BENEFITS Water Meter Flostar Itron DN40
- Low flow accuracy
- Peak flow capacity
- Highly engineered materials
Wide Measuring Range
Flostar M is a single jet meter available in sizes from DN 40 to 150. Its metrological performances far exceedISO/EEC Class C standards. Its low flow accuracy range combined with significant peak flow capacity ensure complete and efficient measurement whatever the faced flow-raters.
Reliability
Flostar M features a drect magnetic transmission between the turbine and the register without any intermediate gearing in the metered water. This results in a very robust and reliable design able to withstand most types of portable water environments. Ease of read in the toughest humid environments (ie: flooded pits) secured by hermetically sealed IP68 register (copper can/mineral glass envelope).
Simple an effective
Simple but highly engineered materials and design enable a very long durability and the best performances for water metering.
Endurance & Peak Flow Resistance
Performance over time is a key requirement for efficient billing. Flostar M features a patented turbine ball pivoting enhancing endurance at low flow-rates. Hydrodynamic balance and turbine design bring resistance at high and peak flows.
- Single jet Class C
- Hermetically sealed register (coppercan/mineral glass envelope)
- Patented ball pivot
- Patented turbine levitation
WORKING PRINCIPLE
Flostar M is a single jet meter. The water jet is canalized by an injector before hitting the turbine. The single jet tapered injector straightens the flow profile. Its large bore area prevents meter over speed by clogging. The high precision design of the inlet .
1 allows Flostar M to meet best accuracy without the need for any bypass or calibration vane adjustment system. The turbine movement directly transmitted to the extra dry register through a magnetic coupling 2 without the need for any intermediate gearing in the metered water. This allows Flostar M to conserve its initial accuracy over time, under the most demanding service conditions of potable water networks. High quality material for the turbine bearings and patented ball pivot 3 design allows detection of leakages initially and over time of the flow profiles. The hermetically sealed copper can/mineral glass enveloppe of the IP68 register 4 is safeguarding the read and integrity of the indicator in the toughest environments (flooded pits, mechanical tampering attempts, …).
COMMUNICATION READY FOR SMART METERING
Flostar M supplied pre-equipped with cyble target.
Allows communication and remote reading through:
- Pulse Output (Cyble Sensor)
- M-Bus protocol (Cyble M-Bus)
- Radio frequency wireless link (Cyble RF)
These Cyble modules allow the Flostar M meter to be connected with various associated systems like our supervision system Water Mind (see specfic leaflet). They are particularly adapted to commercial and industrial applications where a need for frequent meter monitoring is expressed especially in hard-to-read locations.
Key Advantages of Cyble Technology
- No need for additional investment on the meter to implement remote reading.
- Itron standardized meter interface, irrespective of meter technology and widely spread on itron water meters range
- Reliable electronic switching (no wear or bouncing)
- Reverse flow management
- Field proven technology with a 25 years experience.
- Not affected by magnetic tampering.
INSTALLATION REQUIREMENTS
- Flostar M should be installed in the horizontal position with totalizer facing up for optimum performances.
- Installation of a strainer upstream of the meter is recommended to protect the hydraulics from water-borne particles and debris. Please consult Itron’s strainer brochure.
- Flostar M DN 40 is supplied as standard with a strainer and can be fitted with standard non return valve on request)
- Flostar M is not sensitive to flow disturbers (sensitivity class U0D0).
