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, SDI-12 communication (meteorological standard communication protocol); serial RS-232, RS-485 (with adaptor).
The sensing part of the instrument is an anti-abrasion, anti-adhesion and anti-rime coated hemisphere supported by a strong stainless steel arm.
Impact of raindrops or hailstones induce change in internal acoustic pressure.
You can customize the full configuration of the sensor, in a non-volatile memory, with a Plug-and-Play computer connection thanks to a universal USB dongle accessory provided with the sensor.
