Continuously monitor, display, totalize, and data log flow and level through any flume or weir. Easy to Install & Calibrate. Simple, Accurate, & Reliable. Non-Contacting Sensor The OCF 6.1 uses a non-contacting, ultrasonic sensor mounted over a flume or weir to measure flow, or inside / above a tank to measure level. It is accurate, reliable, and verifiable. The separate, watertight electronics / display enclosure can be mounted within 152.4 m (500 ft) of the sensor. The OCF 6.1 continuously displays, totalizes, transmits, and data logs open channel flow or level. Keypad Operating System Use the built-in keypad for fast, easy configuration with menu selection of flume or weir and measurement units (e.g. liters, gallons, etc.) Configuration settings and data logs are password protected and retained during power interruptions. The OCF 6.1 will display on-screen flow or level reports with daily total, minimum, maximum, and average flow / level and will transfer data logs to a USB flash drive. PC software for easy report generation is included. 26 Million Point Data Logger The OCF 6.1 stores time and date-stamped flow values at programmable intervals of 10 seconds to 60 minutes. Daily reports are automatically created and can be viewed right on the instrument’s LCD display including total, minimum, maximum, and average flow rate or levels. Daily reports can also be downloaded easily to a USB drive in .csv format. THE RIGHT METER FOR • Flow Measurement • Tank Level with Flume or Weir: • Influent • Effluent • Sewers • Irrigation • Environmental • Water • Wastewater • Chemicals Smart Operating System The OCF 6.1 tracks flow continuously through a flume or weir. False echoes from turbulence, splashing rain, or snowfall are automatically rejected. Temperature compensation is automatic for high accuracy. The flow rate and totalizer are shown on the large backlit LCD display.

Easy Data Logger Downloads You don’t need a laptop to retrieve log files! Plug any USB Flash Drive into the OCF 6.1 USB output to download data log files automatically. Downloaded files are sequentially named by the meter, so log files from the same, or multiple, instruments can be stored on one flash drive. Greyline Logger Software for Windows Greyline Logger is included with each OCF 6.1. This powerful software displays data in both graph and table formats. You can view flow and level data onscreen, generate reports, and save files to disk. Graphs can be exported as images and data tables can...
