Episode 5: Pitot Tube Leak Check
In this episode I explain the simple process of leak checking a pitot tube and manometer system, as specified in USEPA Method 2.
What you should learn:
- 1. Leak checking the pitot tubes is required before every test, but is optional after the test (T or F).
- 2. The leak check evaluates all connections from the pitot tips to the ____________.
- 3. The leak check must be done at a minimum pressure of _____ inches w.g.
- 4. The Method 2 criterion allows the manometer pressure to drop by _____ inches over a span of ______ minutes.
- 5. Failure of a leak check before a run means that you should:
- a. find the leak and fix it.
- b. disconnect the manometer.
- c. re-check at half the pressure and make a notation on the data sheet.
- d. alert the EPA.
- 6. A failed leak check before a run should always be recorded on the data sheet.
- 7. Once a system has passed a leak check, no additional leak checks are required unless the equipment is dismantled and reassembled (T or F).
