ABB have announced the launch of a new range of flowmeters specifically targeted at the water, waste water and sewage markets. WaterMaster is packed with advanced features and functionality that will bring superior measurement capabilities and enable users to operate more efficiently, reduce costs and increase profitably. WaterMaster is available in the most commonly installed flowmeter sizes: 40 – 300mm.
The new unit incorporates an innovative octagonal sensor design. This improves flow profile and reduces up and down stream piping requirements. By using a higher excitation frequency combined with advanced filtering, WaterMaster also improves measurement accuracy by reducing fluid and electrode noise.
All WaterMaster sensors have a rugged, robust construction to ensure a long, maintenance-free life under the most difficult conditions experienced in the water and waste water industries. 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 unique feature of the WaterMaster sensor is that all sizes are buriable and the installation process involves excavating to the underground pipe, fitting the sensor, cabling to the transmitter and then backfilling the hole.
In the field, WaterMaster incorporates many operator focused features. The backlit, graphical display can be easily rotated through 270 degrees without the need for any tools, allowing field teams to customize the display that best fits their needs. ‘Through-the-glass’ control allows local operator interface to input short, quick data for all user specific parameters.
The universal ABB Human Machine Interface (HMI) simplifies operation, maintenance and training; thereby reducing cost of ownership and providing one common user experience. All product versions utilise a common electronics cartridge to simplify installation and lower spare part costs and inventory. The standard HART protocol enables online modification and monitoring of parameters.
The Advanced Digital Signal Processing (DSP) unit gives improved performance and enables real time measurements for maximum reliability. DSP allows the transmitter to separate the real signal from the noise, thereby providing high quality outputs especially in harsh environments involving vibration, hydraulic noise and temperature fluctuations.
'Fit and Flow' data storage inside WaterMaster eliminates the need to match sensor and transmitter in the field. 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.
Redundant storage of data in both the sensor and transmitter memory is continually updated during all operations to ensure total integrity of the measurement. 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 continuous self checking the sensor and transmitter in the field. All ABB flowmeters 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.
WaterMaster delivers speed, simplicity and ease of use at every stage of the process. The new design raises the bar to the next level for all water, waste water and sewage industry applications.
