snowcontrol solar-based measuring system
for monitoring snow-loads on flat roofs

Mount, launch and ready to go! - smart and cost-efficient

The snowcontrol system is a smart solution for monitoring roof-loads 24/7 caused by snow and ice on flat roofs. In case of hazardous overloads auto-alerts are triggered. Our data portal allows for accessing your current data via any web-enabled device. Our snowcontrol system is mounted immediately onto the roof and operates fully energy-autonomous. There is no need for any intervention with existing roof structures, cables or wires.

THE SNOWCONTROL-SYSTEM IS FOR RENT OR TO BUY

Benefit
Solar-based power supply

  • precise measurement of snowloads in kg/m²
  • simple and quick assembly and disassembly
  • no intervention with existing roof structures
  • fully energy-autonomous, immediately operational, no cables or wiring necessary
  • Optional solar- or power-net supply
  • Integrated emergency power supply up to 240 h
  • auto-notification in cases of emergency via GSM/GPRS module
  • configurable alert levels
  • 24/7 system error control
  • no internet or server connection necessary
  • very low tare weight
  • no more preparatory roof inspections necessary
  • potential connection to building supplies possible
  • power supply and probing electronics built-in waterproof
  • probing by one high-precision load cell up to loads of 1.000 kg
  • use of special plastic materials prevents potential freezing of the load cell plattform

Due to the probing platform's circular shape, the precise load value can be determined by using one load cell only. Any other shape would have to use more load cells and thus increase the risks of potential device failure and false probing data. The system's low height guarantees for accurate mapping of roof waste heat since measurement errors increase with the distance between the probing platform and the roof's surface. Furthermore, snowdrifts as well as the precise layering of varying snow-textures like ice, wet- or powder-snow are captured very well by the scale's open construction. Closed constructions tend to imply the risk of probing errors due to shaded areas.

Since our snowcontrol snow-load measuring-device is a self-monitoring system, users are immediately notified in case of any potential component failure, like the load-cell, which is monitored permanently. Using more than one load-cell would imply monitoring every single one cell. If this is not the case, erroneous load-data may be transmitted. This means, by implication, using more than one cell only does not yield any advantage. For that reason we opted for only one single high-precision load-cell.

Our system design is based on solar operation and power consumption is reduced to a bare minimum. The solar panel is used only to compensate for losses occuring during nighttime. The integrated standby accumulator guarantees for a buffering time of 240h in complete and persistent darkness.

GSM and GPRS modem

Subject
Lightning protection

Technical Data

If desired or needed, our snow-scale may also be connected to 230V, as for one of our customers in Finland it was indispensable. There, a solar-based supply is not sufficient enough during the long and dark winter months. But since our system is equipped with a back-up battery, it remains fully functional even in case of a complete power supply failure.

The snowcontrol-system uses a GSM as well as a GPRS modem, so that there is no server or internet connection is necessary to send SMS messages. Isolated areas in particular are affected by poor or even missing internet connections, so any solution using GPRS only for data transmission or sending SMS messages would be problematic in these cases.

 

Our system does not use any conductive connections to any building facilities. Usually our customers flat roofs already have lightning protections like catchment grills and/or lightning rods, so that it is sufficient to mount our system near these rods or - if existent - within the grills. Snow-scales that have to be connected to 230V supplies need to be integrated into the roof's lightning protection system according to its specific demands, causing higher effort (to be carried out by professional electricians). Therefore our system can be mounted to existing lightning protection facilities by means of a lightning protection clamp.

  • GSM/GPRS unit: SMS and e-mail alert notifications on exceeding configured limits
  • Dimensions: diameter 50cm, height 50cm
  • Measured unit: kg/m²
  • Tare weight: ca. 15 kg
  • Accuracy: +/- 2 kg
  • Max. range: 1.000 kg/m²
  • Material: UV-resistant PVC
  • Connections: no connections necessary (if needed potential-free contacts for connecting to GLT)
  • Mounting: no mounting necessary
  • Power supply: 20W solar panel (if needed 230V grid connection possible)
  • integrated 12Ah standby current storage battery, up to 240h buffering time
