Water Meter Applications

Customers tell us they use GPI meters in water processing and irrigation applications. Examples include: make up water, rinse or feedwater and monitoring of greywater. Greywater alone can be used in irrigation districts, landscaping, golf courses, parks and any industry that uses non-potable water.

HVAC Cooling towers and boilers found in large buildings provide another application. These systems use large amounts of water so efficiency and waste can be a real problem. GPI meters can help solve this problem by monitoring flow rates and water usage. Think of building design sites, cold storage or medical equipment facilities, manufacturing plants and other similar industries.

Reverse Osmosis sites frequently use meters with water. GPI Meters can measure water on the inlet and outlet of large R.O. and chemical feed systems. GPI Meters offer a substantial cost savings when compared to mag meters.
