Continuously Monitor your Fire Installations Against the Risk of Leaking

Continuously Monitor your Fire Installations Against the Risk of Leaking

To prevent fires, regulations require installation of a fixed fire protection system and annual maintenance by a licensed servicing company to check its condition. Following from the above it is now possible to go above and beyond the regulation requirement of annual maintenance which may not be sufficient to cover the remaining periods when the vessel is out at sea alone. The idea of continuous monitoring of fire suppression systems has been made possible and is done by non-invasive ultrasonic liquid level monitoring of the contents within the fire suppression cylinders. This ensures the quantity of agent required to extinguish a fire is always at its designed concentration to guarantee an efficacious fire protection in the event of a fire breaking out in the vessel.

Liquid level monitoring is done using compact, low-cost ultrasonic sensors that are linked to a central control module that broadcasts the liquid level information over WSN allowing dissemination of information to the appropriate parties. The ultrasonic sensors are attached to the walls of the cylinders and propagates ultrasound pulses which travel across the cylinder and returns to its starting position. As the ultrasound pulses travel across the cylinder, the contents within the cylinder will absorb the signal energy in proportions relative to their phases. This ensures that the difference in returned signal above and below the liquid level is always sufficiently large, allowing the liquid level to be identified each time. By fixing the sensor onto the cylinder permanently, any changes in the contents’ level will be identified immediately. Research conducted in the labs have proven accuracies up to 0.1 mm when tested with the commonly known fire suppressing agent cylinders. This proprietary system by Coltraco Ultrasonics is the Permalevel® Multiplex and is capable of using the latest advancement in IoT to collect and disseminate sensor information and forwards them onto the control panel situated on the vessel’s bridge to be integrated as part of the vessel’s overall monitoring system.

Features of Permalevel® Mutliplex

This continuous fire suppression monitoring system is considered to be an accurate and reliable measuring system with integration of ultrasonic leak detector. Here, we have provided you with the major features of Permalevel® Multiplex:

  • Status of each channel shown by LEDs: A set of red and green LED lights specify the status of every cylinder which facilitate a team for maintenance which are responsible to check for the cylinders in case any leakages are absorbed.
  • Multiple Alarm Levels: 2 -40mA Relay Alarms are actually connected to all the channels whereas it permits local alarms to organize for each cylinder individually.
  • Uninterruptable Power Supply (UPS): It acts as a backup system which helps in providing power by using AA 1.5V batteries in case the failure occurs of the main power.
  • Optional Text/Email Alerts: This helps in convenient and instantaneous form of data communication.
  • Strong Magnets: These are beneficial to stick the sensors in place along with extra space for adhesive and a strap which ensures the risk of accidentally removing of sensors.
  • Data logging Ability: The software keeps logs of system errors, system activity and alarm triggers for every month. Due to the storage of these logs as simple texts files, they can be easily and conveniently viewed from outside and inside of the software. This is really helpful and advantageous for insurance companies due to the permanent and correct record of the functioning system accurately.
  • Compatible with Multiple Cylinder Types: Tuning of every channel is individually possible. Moreover, it is done because every cylinder can be different from the last one in weight, size, and pressure and agent type.
  • Sensors: Dedicated sensors are available with each monitoring point which is connected to the particular cylinder for monitoring purposes.
  • Remote Real Time Monitoring Screen: It gives off the information about the current condition of the cylinders in regards to the last contact have been made.
