Water Flow Metering and Telemetry System

Permitted Industrial Users that discharge wastewater to the City of Raleigh sanitary sewer are required to monitor flow for permit compliance (flow limit) and billing. Each industry has an on-site flume or weir, with a flow meter. Flow telemetry is desired for trending and planning. We currently use a modular Teledyne Isco Flowlink telemetry system that can interface with a variety of flow meter brands through a 4-20 mAmp or 2-10 mAmp. Flow data is transmitted over a 2g network to an on-site server database. 1. The 2g network is becoming obsolete and we have been notified that it will sunset in the near future. SIM card replacement is not an option, so we are committed to specific networks and carriers. 2. We have had several telemetry transmission or metering transmission issues that we could not successfully troubleshoot; Product support through the vendor has been inadequate. 3. Several metering systems are aging and will need to be replaced in the near future but we are hesitant to require replacement that may be incompatible with a new telemetry system.
