Leak detection technology / Leak detector

For a clean and protected environment.
Overpressure- and under pressure leak detection technology and leak detector for double walled tanks and pipes. Leak detection systems and Leak detector, which will give an alarm indication, before stored product can enter the environment causing environmental pollution. Leakage sensors for the monitoring of pump sumps, manhole chambers, containment’s. An approved and safe technology for the monitoring.
 

VIMS Vacuum Interstice Monitoring System

VIMS is the smart solution for leak detection and leak prevention for double walled pipes and tanks.

A leak in either of the walls will be detected before any product can enter the environment.

VIMS fulfils the highest level of environmental protection and meets the requirements for class I leak detection EN 13160-2.

The VIMS sensor is directly connected to the FAFNIR VISY-X technology, displaying detailed information:

  • Actual status of the system pressure and vacuum pump
  • Leak alarms for air, water and product
  • I dentification of the monitored tank, pipe orpipe section.

Intelligent monitoring allows appropriate reactions on leak alarms reducing profit losses

Any alarm requires reaction! False alarms need to be avoided. An alarm should be identified immediately revealing the reason and components involved. A pump shut down due to a leak alarm always causes profit losses and should be avoided as long as possible. Depending on the type of alarm the VIMS technology is able to decide if an immediate shutdown of the submersible turbine pump (STP) is needed or not.

VIMS provides the perfect solution:

  1. No false alarms
  2. The FAFNIR VISY-Command GUI displays alarms and differentiates by type and component:
  • Air leak: the secondary wall is no longer tight, but the vacuum in the interstice is still maintained. There is no immediate risk for environmental pollution, which allows a certain reaction time for trouble shooting.
  • Water leak: Ground water enters through the secondary. No immediate environmental risk.
    Allowance for sufficient reaction time for maintenance.
  • Product leak on a tank: STP will continue running to empty the tank. Tank refilling should be prevented.
  • Product leak on a pipe: Primary pipe is leaking. The STP will create overpressure in the interstice and product might pollute the environment. In case of product in the interstice, the STP will be shut down immediately.

The differentiation of air-, groundwater- or product leaks will reduce profit losses caused by unnecessary fuel pump shut offs.
