Non-Contacting 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.

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.

Built-in Data Logger Creates Flow Reports
Save time and labour — flow information is stored automatically

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.

Greyline Logger software for Windows
Greyline Logger is included with each OCF 5.0. This powerful software displays data in both graph and table formats. You can view flow data onscreen, generate flow reports and save files to disk. Graphs can be exported as images and data tables can be exported as delimited text files, or directly to Microsoft Excel.

Non-Contacting Ultrasonic Sensor
Each OCF 5.0 includes a non-contacting PZ15 sensor designed for the special requirements of open channel flow measurement. The sensor can be installed 8″ (203 mm) or more above the highest water level. The ultrasonic sensor beam is narrow enough to work on very small flumes and powerful enough for really large applications. The OCF 5.0 automatically tunes to extended cable lengths up to 500 ft (150 m) lengths.

OCF 5.0 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.

Programmable for any Flume or Weir
The OCF 5.0 includes a built-in 5-button keypad for fast, easy calibration. Select your choice of engineering units (gallons, liters, cubic meters, etc.) and choose your flume or weir type from the menu.

The flowmeter also supports entry of flow formulae for non-standard flumes and weirs. ‘Find K&n’ software (included) can be used to calculate non-standard calibration constants for entry into the OCF 5.0 calibration menu.

Built-in control relays can be programmed for flow alarms or a flow proportionate pulse for remote totalizers, samplers or chlorinators. The isolated 4-20mA (or 0-5V) output can be connected to chart recorders, remote displays and controllers.

Smart Operating System
The OCF 5.0 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. Flow rate and totalizer are shown on the large backlit LCD display.

Fiberglass and Radio Frequency Transparency

In today’s connected world, we depend on cellular telephone signals, Wi-Fi networks and over the air radio and television signals. Wi-Fi and Bluetooth connectivity are essential to on-site work environments. Steel structures significantly disrupt these signals. Fiberglass Grating is an essential part of building structures that are “electronically transparent” and do not interfere with radio frequency transmissions.
