Rain & Hail Monitoring
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 and wind laminar air friction induce change in internal acoustic pressure. The two excitations are discriminated as independent signals as a result of a specific acoustic, mechanical, and electronic design.
The configuration of the sensor can be fully customized, in a non-volatile memory, with a Plug-and-Play computer connection thanks to a universal USB LINK accessory.
