The design brings the sensor closer to the ideal square sensor geometry without the inherent problems of stresses caused at the four corners.
By improving the flow profile, the octagonal design minimises the upstream and downstream pipe lengths required from the point of installation, greatly reducing the cost of fitting the meters into new or existing pipelines.
Another world first is the inclusion of onboard verification capability.

Called VeriMaster, it assures operators of the performance of the meter through constant self-checking.
When coupled with the VeriMaster software tool, it will enable operators to produce a printed verification certificate for regulatory compliance.
By using high frequency excitation combined with Digital Signal Processing (DSP) technology, the WaterMaster transmitter is able to more clearly separate the sensor signal from the background noise, thereby providing high quality outputs especially in harsh environments involving hydraulic noise, pH changes and temperature fluctuations.
Improved software filtering also ensures a faster speed of response, giving operators real time measurement of flow conditions, resulting in more accurate and reliable flow measurements.
All WaterMaster sensors have a rugged, robust construction to ensure a long, maintenance-free life even under the most difficult conditions experienced in water and waste water applications.
The sensors are inherently submersible (IP68, NEMA 6P) as standard, ensuring suitability for installation in chambers and metering pits which are liable to flooding.
A key feature of the WaterMaster sensor is that all sizes are buriable; installation merely involves excavating to the underground pipe, installing the sensor and wiring the factory pre-potted cabling to the transmitter and then backfilling the hole.
The WaterMaster range incorporates many operator focused features.
The transmitter can be easily rotated through 270 degrees, allowing operators to customise the display to best fit their needs.
"Through-the-glass" control technology provides a local operator interface for inputting short, quick data for all user specific parameters without removing the transmitter cover.
Operation has been simplified by the use of the new ABB universal Human Machine Interface (HMI), which has now been extended across its range of instrumentation products.
Enabling operators to easily scroll through and select options, the HMI simplifies operation, maintenance and training, reducing cost of ownership and providing a consistent user experience.
All product versions utilise a common electronics cartridge to simplify installation and lower spare part costs and inventory.
Standard HART protocol enables online modification and monitoring of parameters.
Installation is further simplified by the 'Fit and Flow' data storage feature in the WaterMaster.
On initial installation, the self-configuration sequence automatically replicates into the transmitter all calibration factors, meter size and serial numbers as well as customer site-specific settings.
This eliminates the opportunity for errors and leads to increased speed of start-up.
Measurement integrity is ensured by redundant storage of data in both the sensor and transmitter memory, which is continually updated during all operations.
The on-board sensor memory eliminates the possible problems associated with pluggable data memory modules.
WaterMaster is proven to be robust and reliable, with unmatched diagnostic capabilities providing the right information to keep the process up and running.
Alarms and warnings are classified in accordance with NAMUR NE107.
The meter is also verified to OIML R49 type 'P' requirements to ensure the highest accuracy and long term performance of the system by continuously self checking the sensor and transmitter in the field.
All ABB flow meters are designed and manufactured in accordance with international quality procedures (ISO 9001) and are calibrated on nationally-traceable calibration rigs to provide the end-user with complete assurance of both quality and performance.
