The HailFlow HF4 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 a three layers polished stainless disc supported by an unbreakable stainless-steel arm. Impacts of hailstones (or any other lithometeors in the same range of kinetic energy) induce a measurable change in internal acoustic pressure.
The sensor is able to distinguish between 15 classes of hailstone diameter, ranging from 0.5 to 8 cm, with a capability of counting up to 25 solid impacts per second.
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.
