Non-Contacting Sensor
The OCF 6.1 uses a non-contacting ultrasonic sensor mounted
over a ume or weir to measure ow, or inside/above a tank to
measure level. It is accurate, reliable, and veriable. The separate,
watertight electronics/display enclosure can be mounted within
500 ft (150 m) of the sensor. The OCF 6.1 continuously displays,
totalizes, transmits, and data logs open channel ow or level.
Keypad Operating System
Use the built-in keypad for fast, easy conguration with menu
selection of ume or weir and measurement units (e.g. gallons,
liters, etc.) Conguration settings and data logs are password
protected and retained during power interruptions. The OCF
6.1 will display on-screen ow or level reports with daily total,
minimum, maximum, and average ow/level and will transfer
data logs to a USB ash drive. PC software for easy report
generation is included.

Precision Flow Measurement
Built-in Data Logger Creates Flow Reports. Save time and labor — ow
information is stored automatically.
26-Million Point Data Logger
The OCF 6.1 ores time and date-amped ow values at programmable intervals of 10
seconds to 60 minutes. Daily reports are automatically created and can be viewed right
on the inrument’s LCD display including total, minimum, maximum, and average ow
rate or levels. Daily reports can also be downloaded easily to a USB drive in .csv format.
Easy Data Logger Downloads
You don’t need a laptop to retrieve log les! Plug any USB Flash Drive into the OCF 6.1
USB output to download data log les automatically. Downloaded les are sequentially
named by the meter, so log les from the same or multiple inruments can be ored
on one ash 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 ow and
level data onscreen, generate reports, and save les to disk . Graphs can
be exported as images and data tables can be exported as delimited text
les, or directly to Microsoft Excel®.
• Display, analyze, and export log les in graph and table formats
• Generate reports including totalizer, minimum, maximum, and
average ow rates and level
• Convert measurement units
• One-click export to Microsoft Excel

Non-Contacting Ultrasonic Sensor
Each OCF 6.1 includes either a non-contacting PZ15 sensor designed for the special
requirements of open channel ow measurement, or a PZ32T sensor designed for the special
requirements of tank level measurement. The ultrasonic sensor beams are narrow enough to
work on very small umes, and powerful enough for really large applications. The OCF 6.1
automatically tunes to extended cable lengths up to 500 ft (150 m) lengths.
OCF 6.1 Outputs Included
Connect the OCF 6.1’s isolated 4-20 mA output to external displays, chart recorders, or
controllers and use the built-in relays for ow/level alarms and ow proportionate pulse to
samplers, chlorinators or external totalizers.
Retains Memory during Power Interruptions
Date, time, calibration data, and user settings are ored and retained in back-up battery protected memory. Data log les
are in ored Secure Digital (SD) non-volatile memory.
Security
Access to the OCF 6.1 calibration menu and settings are password protected when enabled.
