Global Water's Open Channel Flow Monitor is reliable and accurate for measuring and totalizing open channel flows for all flumes and weirs, as well as for any gravity-type open-channel flow application.  The flow meter measures water depth with Global Water's highly accurate pressure transducer, and the unit's electronic circuitry instantly calculates and displays water flow and totalizer values for any depth-to-flow relationship in any engineering units.  The Open Channel Flow Monitor is easy to set up in the field using a unique four-button programming system.

The water monitor displays flow rate on a large 6-digit LCD screen. The totalized output is shown on a second LCD display. The display reads in user-defined units of flow, including MGD, CFS, GPM, m3s.  The Global water flow monitor also produces an analog 4-20 mA output signal that is proportional to flow. This can be used for chart recorders, dataloggers, or as an input to telemetry or process control systems. In addition, the flow rate meter has a flow-proportional output signal for triggering water samplers.
