Monitor Emissions can find leaks of ANY gas (Nitrogen, Air, Oxygen, Hydrogen, etc.) utilizing our two forms of Portable Ultrasound, Airborne Ultrasound and Acoustic Cameras. It’s commonly thought that the FLIR Gas Cameras can detect Nitrogen Leaks but they can only detect hydrocarbon leaks, so for Plant Start-Ups and other Nitrogen / Air / ANY Gas Tests we utilize our incredibly sensitive Ultrasound equipment.

Our Ultrasound Gear can detect a leak up to 300ft (91m) away audibly through a headset as a rushing sound and the decibels register on the display/meter. This assists the technician to determine the leak source and its severity. Upon finding the leak source our Acoustic Camera that allows the user to “See the Ultrasound” can pinpoint leaks as small as 0.016I /min, while showing you a real time picture allowing you to visualize the exact location of the leak and calculate how much energy you are wasting.

This leak detection equipment operates by “hearing” the turbulent flow of any gas through an orifice. The typical human ear can hear in the range between between 20Hz to 20,000Hz (20kHz) . Our Ultrasound devices detect the 20,000kHz to 100,000kHz range and heterodyne this signal to our audible range. If ambient noise becomes a concern, our technicians can frequency tune the Ultrasound device to narrow the instrument's reception field and shield it from conflicting ultrasound interference. Clients are regularly surprised at the speed and efficiency of our leak detection surveys as they typically span as long as it takes to walk around a facility and tag / record the found issues.
