Data Delivery Services is truly a “hands-off” approach to open-channel sewer flow monitoring. The service is budget-friendly for both short- and long-term flow-monitoring applications. Hach installs and maintains its Web-enabled flowmeters and users never have to visit the site. Unedited data from Hach flowmeters can be conveniently accessed 24/7 from any Web browser via a secure password-protected site.
