  "term": "Flow Recording",
  "field": "Environment",
  "definition": "The recording of flowrate measurements, often by an automatic recording device. Typically an instrument is used to measure a physical parameter(s) that can be easily related to flowrate, such as water level, water velocity, or pressure variances in a closed conduit. This parameter(s) is then recorded and used to calculate the flowrate at a given time. For example, in wastewater treatment, combined sewerage systems, and stormwater conveyances one practice is to record the height of the free water surface behind a weir and use this measurement to calculate flowrate using the calibrated weir equation, although other measurements and calculation schemes may be used.",
