FlowVis
Digital Flow Meters

This Means More… FlowVis flow meters have been revolutionizing the way flow is measured in pool and spa applications since their inception in 2012. FlowVis Digital upgrades offer increased functionality and convenience to an already highly capable NSF 50 certified flow meter.

Digital options include the FlowVis Digital and FlowVis Digital Signal Converter, each of which is available for the vast majority of analog FlowVis models. A complete list of compatible FlowVis models can be found on this page.

FlowVis Digital Sensor (FV-D-SO)

FlowVis Digital sensor

  • The FlowVis Digital Sensor (FV-D-SO) is a standard feature of any FlowVis Digital configuration. The sensor mounts directly on the side of any FlowVis model and provides a non-linear 4-20mA signal to e.g., FlowVis Digital, FlowVis Digital Signal Converter, or an automation system.

    • Housing Material: Polycarbonate

    • Cable Length: 26.25 ft. (8M)

    • 4-20mA Scaled to: 4mA = zero flow, 20mA = max flow rate limited of installed FlowVis

    • 4-20mA Output Format: Voltage sourced from connected equipment, e.g., FlowVis Digital, FV-D Signal Converter, automation system, etc.

    • 4-20mA Maximum Load: 250 Ohms
