Limitations
- Tedious connections before carrying out the test.
- The mounting chamber will leave ugly holes on the wall as drilling is necessary for the insertion of anchor bolts.
- The problem of lateral migration is rather prominent when air pressure is applied. This will cause inaccurate readings
- The apparatus is not able to allow for dynamic variability of air pressure with time.
- Although the apparatus is designed to facilitate mobility for field use, the small test area of 0.18m2 makes testing at low rates such as 0.21l/min per m2 difficult. This is because when translated into test flow rate for 0.18m2 test area, is only 0.038l/min. No suitable nozzles could be found for this low rate.
