FLOW & LEVEL CONTROL
Preventing leaks allows pipeline operators to avoid polluting the environment, paying big fines, losing money in lost product, and tarnishing their brand
methods and procedures are analysed to ensure compliance with API RP 1130. The operator’s Leak Detection Program is
systematically analysed, using the API RP 1175 Gap Analysis Tool, to ensure that all processes have been performed and documented, including the selection of leak detection methods, the performance targets and metrics, testing, control centre procedures for recognition and response, training, and management of change. (3) Physical State: The next stage is to
review the leak detection system currently in place, determining whether there is newer hardware available that can perform better, asking questions such as whether there have been operational changes that impact software requirements, and whether newer security threats have emerged that must be addressed. These questions are answered in two sets of data: system check, the current health and operational status of the leak detection system in place; and uptime analysis, a historical review of the previous 12 months calculates the percentage of time the system has been running fully functional,
degraded or nonfunctional. (4) Performance: The testing of installed leak
detection systems and the organisation’s response to leak events is obviously critically important to evaluating performance and to implementing and measuring improvements. Testing is used to determine the quality and sensitivity of the leak detection system: how large does the size and flow rate of the leak need to be to trigger an alarm and how well can the system pinpoint the leak’s location? Tests fall into two categories: simulated leak tests and physical leak tests. In simulated leak testing, artificial leakages of different sizes are generated and the
organisation’s response is observed. In a physical leak test, the installed leak detection system’s performance and the organisation’s response can also be measured by a physical leak test involving actual withdrawal of varying amounts of fluid from the pipeline. A complete pipeline leak detection audit
gives visibility to the health and effectiveness of the leak detection system and insight into the organisation’s readiness to fully respond to alarms. Leak prevention avoids polluting the environment, fines and tarnishing brands.

ECO PHYSICS nCLD "Facelift" boxed solutions nCLD AL3
Measurement of: NO · NO2 · NOX · NH3
Compact analyzer with integrated pump Simultaneous NO, NO2, NOX and NH3 measurement Intuitive graphical user interface Internal data logger and status recorder Remote operation/control, Power DOWN/UP USB, HDMI, LAN/WLAN, Bluetooth, RS-232, Analog I/O
The three-channel chemiluminescence based NOX/NH3 analyz- ers of the nCLD "Facelift" box-solution analyzers detect NO, NO2, NOX and NH3 at concentration ranges from 0 - 50ppb to 0 - 50ppm with a minimal detection limit from 0.4 ppb. The three-channel nCLD AL3 includes an internal pump and comes as a fixed and pre-configured analyzer. The slightly modified front panel has been equipped with an additional Power-button and a new internal PC. Additionally, are all nCLD-models capable of a remote power down/up including a failsafe feature. The nCLD AL3 is the ideal instrument for ambient air monitoring, either in- stalled in racks, fixed monitoring stations or mobile laboratories. The instrumentʼs inlet operates at ambient pressure. Calibration of the unit runs quick and automatic while all necessary data is continuously stored and readily available anywhere and at any time. According to ISO EN 14211.
