Easyflow

Current Meter for Professionals

EasyFlow is a highly ergonomic, waterproof instrument with a conductivity probe and 10 m cable. It comes in a nylon shoulder bag with 3 calibration doses, EasyViewer software, a memory aid and a USB communication cable. So it’s easy to carry around.

The EasyViewer software enables data to be transferred to a PC, the gauging curve to be viewed and, if necessary, the flow rate calculation to be corrected. It is very useful, even necessary, to check the quality of the gauging by viewing the curve.

Main software functions:

  • Loading measurement data from EasyFlow
  • Display of the gauging curve and possibility of graphically correcting the flow calculation
  • Addition of information on gauging, such as water level height

Skywatch® BL-1000

Bluetooth® weather station with wind speed and direction, temperature, humidity, barometric pressure, tracking and data logger with alarm function

The Skywatch BL-1000 is a rugged portable weather station designed for rapid deployment. It has been developed by and for professionals who need to measure and document local weather conditions, such as firefighters, incident responders, police, outdoor exhibitions, stage operators, construction companies and agriculture.

The Skywatch BL-1000 is a complete weather station that provides accurate measurements of wind speed and direction, temperature, humidity and barometric pressure, and transmits them to a dedicated smartphone application and secure data warehouse.

The BL-1000 is capable of storing data locally on an iOS™ or Android™ smartphone or tablet, and transferring measurements to Weathercloud with map visualisation. Data can subsequently be extracted from the map to a CSV file (comma separated variable file) for later processing evaluation.

Weather Station

Skywatch® Wind Alert

This instrument has been designed to warn of wind speeds that are dangerous for the safety of people and property.

Main features of Skywatch Wind Alert :

  • multidirectional propeller which measures the wind horizontally and vertically (including turbulence behind an obstacle).
  • If the programmed limits are exceeded, this is indicated by orange (pre-alarm) and red (alarm) LEDs and a loud audible signal.
  • On-site installation in seconds on tubes or structures up to 40 mm thick.
  • Clamp with ball joint for fixing.
  • Pre-alarm and alarm levels and times can be programmed by connecting to a PC with dedicated software.
  • Alarms are recorded and dated
  • Long battery life: 2 years continuous use, low battery indicator, automatic switch-off when stored in its box.
  • Robust, weatherproof casing.
  • Designed and manufactured in Switzerland.
Applications

How it works
  • Continuously measures wind speed and triggers alarms.
  • Visual and audible alarms indicating pre-alarm and alarm levels.
  • Record of alarms triggered.
  • Extraction of CSV (comma separated variable) data for the alarm log, by connecting the device to a PC.

Skywatch® WWS

This instrument has been developed to protect people and property that are or may be subject to high winds.

It consists of 2 components:

  • A wind strength display unit with 4 programmable alarm thresholds (2 min and 2 max).
  • A multidirectional propeller (wind sensor) which measures the wind horizontally and vertically (turbulence behind the obstacle). The propeller transmits its signal magnetically to a transducer (wind sensor) located at the end of the connection cable linked to the screen. This transmission system simplifies installation.

Skywatch® WWS is particularly recommended for :

  • Construction sites: scaffolding, cranes, etc.
  • Public buildings: schools, sports grounds, etc.
  • Sports and leisure: campsites, mobile homes, marinas, airfields, ski lifts, sports competitions, etc.

Four values can trigger the alarm. These values can be determined on the rising or falling edge and the alarm duration can be set for each alarm.

There are four relay outputs in kits 2 and 3 (described below). The idle state of each relay can be selected between no (open) and nc (closed). The user can assign a relay output to each alarm.

Functions
  • Measurement of average wind speed
  • 2 minimum / 2 maximum audio/visual alarms

Porosimeter

MK2+

The MK1 porosimeter, developed in 1988 for the paragliding industry, quickly became a world reference in porosity measurement, with several thousand units sold. Reliable and fast, it is now used in many sectors to assess the permeability of fabrics – an essential factor in guaranteeing safety and performance.

Since 2017, the MK2 model, with a remote probe and an accessory designed for high-porosity fabrics, has further extended the measurement possibilities of this porosimeter.

Main applications :

  • Porosity measurement for manufacturers of paragliders, hot-air balloons and spinnakers.
  • Preventive inspection of fabric condition to assess degradation and prevent accidents
  • Verification of used equipment and in-depth analysis of fabrics
Data displayed
  • The measurement pressure is 100 mm of water, i.e. 10 mbar or 10 hPa. The result is given in seconds (time taken for 0.25 litres of air to pass through 38.5 cm2 of fabric at 10 mbar pressure).
