Horizontal Hydrant Flow Meter

Our Horizontal Hydrant Flow Meter provides unrivalled accuracy of ±0.5% within a wide flow range. The swan neck design ensures that the electromagnetic sensor of the AquaMaster is always full. As the sensor has no moving parts, debris often found in the water supply or valves does not cause any damage which is common with paddle wheel technologies.

Using ABB’s electromagnetic AquaMaster with an integrated data logger, the Hydrant Flow Meter can record continuously with up to 12 months of battery life without the need for recharging. The sensor continuously records, even when the digital display is off and/or the sensor is empty, ensuring every litre, cubic meter, or gallon is recorded.

The Horizontal Hydrant Flow Meter is ideal for many portable monitoring applications such as hydrant verification, meter verification, flushing, tank filling, and revenue purposes.
