Please fill out the below fields to schedule your 3G FL900 Flow Logger to be converted to 4G at the service bench. If your logger is aging and nearing the end of its life, please contact your local Flow Representative to discuss options for upgrading to a new FL900 4G Flow Logger.

Please note, we can only accept work orders with 5 FL900 conversions at a time. A Hach bench service representative will contact you with a quotation to ship the logger(s) into the service bench within 24 hours.

Due to the high demand for service conversions, loaners are only available to service contract customers on a first come first served basis. If you are a service contract customer needing a loaner FL900, please specify in the comments section.

For any questions while completing the form, please contact 800-227-4224. For technical questions, please follow the prompts for technical support.
