The ClampOn DSP Leak Monitor detects leaks or flow-throughs, even with low differential pressure over the measuring point on most 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.
The basic theory is that a leak creates a very high-frequency noise, it can be monitored using 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 recognises 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.
A leak in an oil or gas flow line is a highly dangerous situation so it is extremely important for the operator to be warned about any leak immediately as it occurs.
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 usually 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 which are listed below:
