Leak Monitor

The ClampOn DSP Leak Monitor detects small and medium leaks or flow-throughs, even with low differential pressure over the measuring point on pipes and valves. The ClampOn DSP Leak Monitor has been developed with the aim of offering a product that can quantify a leak through a closed valve. The ClampOn DSP Leak Monitor is qualified as a subsea and topside monitor.

How it works

The basic theory is that a leak creates a very high-frequency noise that can be monitored by an ultrasonic sensor. In a «non-leak» situation the ultrasonic pattern will be stable, but when a leak occurs the signature will change drastically. ClampOn’s DSP technology distinguishes and eliminates background noise unrelated to leakages so that the hiss from the leaks can warn the operator. The system also includes a program or data-base that helps to monitor and indicate the volume of the leak.

Advantages

A leak in an oil or gas flow line is a highly dangerous situation – upstream as well as downstream, so it is extremely important for the operator to be warned about any leak immediately should it occur.

A leak in a flow line, valve, flange or any other component can compromise safety and may also lead to a shutdown at the production stage or down-stream at a refinery or terminal.

A product leak normally has a very low flow-rate, which is determined by the size of the defect, the properties of the fluid and the pressure differential. There are a number of advantages in using the DSP Leak Monitor to monitor valves:

  • Reduced loss to flare
  • Gas leak to the sea
  • Reduced loss to the atmosphere
  • Reduced process loss
  • Maintenance planning

The ClampOn DSP Leak Monitor helps operators identify and quantify sources of gas/liquid leakages, thus enabling them to take appropriate action. Customers have successfully used the ClampOn Leak Monitor to identify cross-flow in valves connected to the manifold.

Integration

Our instruments can easily be integrated into any existing or new control system. A computer with our software is often used in-between our instruments and the control system. The computer will be used for calculations and all recorded data will be stored for analyzing and calibration purposes.

We always recommend using the digital interface due to following benefits:

  • Two way communication enabling instrument software update and configuration
  • Full signal range resolution
  • All sensor data can be transmitted
  • No signal loss
