Water Solutions

Under normal installation and operating conditions, Goldcard Water Solutions water meters are designed for a service life of at least 10 years.

The actual service life may vary depending on factors such as water quality, operating pressure, installation environment, working conditions, and maintenance.

Depending on the product model and communication technology, the battery life is at least 10 years.

Most smart water meters are equipped with a highly reliable sealed battery that requires no routine maintenance and is generally not field-replaceable.

For applications with frequent valve operations—such as prepaid water metering projects in Africa—we offer ultrasonic plastic-body water meters with an external valve, allowing only the external valve to be replaced when necessary.

Our products comply with a range of internationally recognized standards and certifications, including:

• OIML R49
• MID
• CE
• WRAS
• ACS

Certification availability may vary depending on the specific product model.
