    HydroPoint has relationships with water departments across the country. Some water companies have ordinances that limit your ability to open the meter box or utility vault. Other water companies may have ordinances that limit the installation of 3rd party devices on the water meter. If your water provider has issues attaching a flow monitor non-intrusively to the water meter, HPDS has alternate solutions available to capture total building water consumption. 

    If your water meter is not listed or you have questions, please contact us at We will be happy to review photos of your water meter to confirm compatibility.
