Documents & notices

Please download here the original ISAW-Toolbox software suite, for any model of your sensor.

The ISAW-Toolbox software suite is an all-in-one toolbox utility that allows fully configuring and operating your sensor.

You can download the ISAW-Toolbox software suite in two ways:

  • use the standard setup installer (.exe, .dpkg),
  • or download the non-intrusive standalone archive (.zip, .bz2).

Select the package that match your Operating system (Windows, Linux or Mac) and system architecture (32 or 64 bits), download the package.

To use the installer (.exe, .dpkg): Click on the downloaded file and follow the installation process.
From the archive (.zip, .bz2): Unzip the downloaded file and click on the utility you need.”

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.
