The RainFlow RF4 sensor: an ultra-robust instrument
It is a very low-power, maintenance-free and totally sealed acoustic instrument with no mobile parts.
The instrument includes a dedicated analog conditioning module, a digital I/O module and an analog restitution module that can be connected conveniently to almost any external central unit (data logger, industrial module interface, instrumentation DAQ, USB port).
It features continuous or pulse analog voltage outputs and supports SDI-12 communication, serial RS-232, and Modbus RTU RS485 (using an optional adapter).
The sensing part of the instrument is an anti-abrasion, anti-adhesion and anti-rime coated hemisphere supported by a strong stainless steel arm.
It measures and distinguishes liquid and solid precipitation. It is especially optimized for rain measurement and hail detection.
The full configuration of the sensor can be customized at any time, in a non-volatile memory, with a Plug-and-Play computer connection thanks to the universal USB dongle accessory provided with the sensor and the free ISAW-Toolbox software suite.
