3.10 System Checks
Leak test
Before the system is filled and/or commissioned, do a leak test with
compressed air (or other inert compressed gas) or water. The minimum test
pressure must be equal to the normal operating pressure. The maximum
pressure is the MWP.
• Apply pressure at a convenient point on the system.
• Apply an applicable leak test solution to the impulse piping, valves,
transmitter connections and joints.
• Look for a continuous stream of bubbles.
• Bleed the system.
• Do all the necessary repairs, and test the system again.
• Return the system to the original configuration.
Transmitter test
Connect the necessary instruments to monitor the pressure signal. If
necessary, connect a milliammeter to measure the output from the transmitter.
• Apply power to the transmitter.
• Apply the applicable pressure.
• Monitor the pressure signal.
Refer to the 'Operation' section for the procedures to set up and operate the
transmitter.
