Our FOSM Monitoring Complex 

FOSM Complex

All of the above VOSK units form part of our FOSM Monitoring Complex. Which units are to be used is dependent on the task the FOSM Monitoring Complex is tasked with. The FOSM Complex is comprised of the following elements:

All-Weather Field Cabinet (AWFC)

This units contains the VOSK unit and all of the necessary accessories for their operation. It can tolerate temperatures of up to 80°C

VOSK Server Unit 

This unit is designed for the transfer of information and remote monitoring. 

The transfer can be by wire or wireless. For wireless transfer, we can provide information encryption devices for safe transfer. The VOSK Server is not connected to the open net, making it immune to wireless hacking attacks

ARM Operator Monitoring Station

The monitoring station is used to review the real time data from the VOSK units. It is typically located in the control room. The interconnectivity of our technology allows to monitor numerous VOSK units from one location. The display of information is fully customizable to the client's preference, all data stored for a minimum of two years 

Our FOSM Monitoring Complex features the following: 

  • Integration - OPC and Custom Protocol  to assure connectivity to existing monitoring systems or SCADA Platforms 

  • Redundancy - Reserve VOSK units & FOC Light Loop Options 

  • Electric Passivity - Does not interfere with existing equipment

  • Informational protection 

  • Durability and ease of maintenance 

  • Full adaptability and customization 

  • Reliability and Accuracy
