ABB Electromagnetic flowmeter WaterMaster
Overview
The ABB WaterMaster is an electromagnetic flowmeter engineered specifically for the water, wastewater, sewage, and effluent sector – a purpose-built instrument rather than a general-purpose ProcessMaster adapted for water duty. Its defining feature is direct submersible and buriable installation, letting utilities install a flow measurement point without the cost of building a dedicated meter chamber.
Seven Star LLC supplies the WaterMaster as a trusted supplier of ABB products across Oman and the GCC, specifying it for municipal and industrial water utilities where meter chamber construction cost is a genuine project driver.
Operating Principle
Like every ABB electromagnetic flowmeter, the WaterMaster measures flow through Faraday’s law of induction – a conductive fluid moving through a magnetic field generates a voltage proportional to velocity, detected by electrodes and converted directly into a flow rate – but its housing and sealing are engineered specifically to survive direct submersion or burial rather than requiring a protected, dry installation environment.
This submersible/buriable capability removes the meter chamber cost and maintenance burden that a standard indoor-rated flowmeter would require on a buried utility main, a meaningful capital and lifecycle cost saving across a large water distribution or sewage network.
Engineering Design of the WaterMaster
The WaterMaster is available across an exceptionally wide size range – full-bore models from DN40 to DN200 (1.5 to 8 inches), an extended range spanning DN10 to DN2400 (0.38 to 96 inches), and a reduced-bore option from DN40 to DN600 (1.5 to 24 inches) – covering everything from small service connections to major transmission mains.
It carries OIML R49 and MID certification for legal metrology compliance in water utility billing applications, digital signal processing for measurement stability, and onboard diagnostics for operational monitoring, with a field-ready configuration interface for commissioning without specialized tools.
Key Features
- Direct submersible and buriable installation, no meter chamber required
- Full-bore, extended-range, and reduced-bore size options up to DN2400
- OIML R49 and MID certification for legal metrology and utility billing
- Digital signal processing for measurement stability
- Onboard diagnostics for operational monitoring
- Field-ready configuration interface for straightforward commissioning
- No moving parts, no pressure drop across the meter
- Purpose-built for water, wastewater, sewage, and effluent duty
Industrial Applications
The WaterMaster is used across municipal water distribution networks, wastewater and sewage lines, and effluent monitoring points in Muscat, Sohar, Salalah, and the wider GCC, particularly where a buried or submerged installation avoids the cost of a dedicated meter chamber.
Seven Star LLC, as a trusted ABB supplier, positions the WaterMaster specifically for water-sector utility metering, distinct from the general-purpose ProcessMaster range (see related products) which targets broader industrial process applications rather than buried water infrastructure.

Why Choose Seven Star LLC for the ABB WaterMaster
Direct burial and submersible installation is the WaterMaster’s defining advantage, but it also means the meter’s cable entries, housing seals, and communication method need to be specified correctly for a buried or flooded chamber environment from the outset, since a mistake discovered after burial is far more costly to correct than one caught before installation. Before confirming an order, Seven Star LLC verifies the installation environment, buried, submerged, or chamber-mounted, along with the required communication method back to your SCADA system, ensuring the specific WaterMaster configuration genuinely and precisely matches how it will actually be installed on site.
For municipal and industrial water utilities weighing the WaterMaster’s direct-burial capability against the cost of a traditional meter chamber, our engineers help work through the real installation cost comparison in detail for each specific project, since the WaterMaster’s overall value proposition depends heavily on meter chamber construction costs that can vary quite considerably by specific site and local ground conditions. Where a utility is standardizing on WaterMaster across a metering program, we are always glad to review the entire existing installation base in detail before recommending any rollout plan for additional metering points.
Eliminating Meter Chamber Construction Costs
A traditional flowmeter installation on a water or wastewater main typically requires a purpose-built meter chamber, concrete construction, access covers, drainage, and often ventilation, all of which represent a substantial civil works cost that can very easily exceed the price of the meter itself on a large-scale project. The WaterMaster’s direct-burial and submersible design removes this civil works requirement entirely, letting utilities install a new metering point by simply excavating a trench, placing the meter, and backfilling the site, which genuinely and meaningfully changes the underlying economics of expanding a metering program across a large distribution network.
Seven Star LLC, as a trusted supplier of ABB products, helps water and wastewater utilities across Oman and the GCC evaluate WaterMaster deployment against traditional chamber-based alternatives on a genuinely honest cost basis, and we coordinate with ABB on documentation, cable specifications, and communication protocol options to help ensure each installation is specified correctly the first time, since correcting a buried meter’s configuration after it has already gone into the ground is a genuinely costly undertaking that a proper upfront specification simply avoids entirely from the start.
