IFQ Logger

The IFQ LOGGER is a portable converter and logger for Flow-Tronic flow sensors. It has a digital serial RS485 communication port with specific communication protocols for RAVEN EYE or BELUGA flow sensors and a 4-20 mA input for external levels.
The IFQ LOGGER combines high performance with low power consumption. The device requires a 12VDC rated power supply provided by either an optional battery or solar panels.
The IFQ LOGGER retains the same simple configuration enhanced by the IFQ MONITOR, and remains in line with the flexible and modular structure introduced by the RAVEN-EYE. All flow sensors are interchangeable on site.
A potential free contact output is available for users who need an output for samplers or any other instrument.
