Non-Contacting Ultrasonic Sensor

The OCF 5.0 uses a non-contacting ultrasonic sensor mounted over a flume or weir to measure flow. It is accurate, reliable and verifiable. The separate, watertight electronics/display enclosure can be mounted within 500 ft (150 m) of the sensor. The OCF 5.0 continuously displays, totalizes, transmits and data logs open channel flow.

Keypad Operating System

Use the built-in keypad for fast, easy calibration with menu selection of flume or weir and measurement units (e.g. gallons, liters etc). Calibration values and data logs are password-protected and retained during power interruptions. The OCF 5.0 will display on-screen flow reports with daily l, minimum, maximum and average flow and will transfer data logs to a USB flash drive. PC software is included.

2 Million Point Data Logger

The OCF 5.0 stores time and date-stamped flow values at programmable intervals of 10 seconds to 60 minutes. Daily flow reports are automatically created and can be viewed right on the instrument’s LCD display including total, minimum, maximum and average flow rates.

Easy Data Logger Downloads

You don’t need a laptop to retrieve log files! Plug any USB Flash Drive into the OCF 5.0 USB output to download data log files automatically. Downloaded files are sequentially named by the flowmeter so log files from the same or multiple instruments can be stored on one flash drive.

Outputs Included

Connect the OCF 5.0's isolated 4-20mA output to external displays, chart recorders or controllers and use the built-in relays for flow/level alarms and flow proportionate pulse to samplers, chlorinators or external totalizers.

Retains Memory During Power Interruptions

Date, time, calibration data and user settings are stored and retained in back-up battery protected memory. Data log files are in stored Secure Digital (SD) non-volatile memory.

Password Protected Security

Access to the OCF 5.0 calibration menu and settings are password-protected when enabled.
