We want to know what happens to our pipelines while we’re not there. The majority of plants in our system are unmanned so when events like shut downs due to mechanical failures or power interruptions occur causing pressure transients in the pipe, we don’t know what kinds of pressures they are subjected to. We assume that all of the safety devices like relief valves operate properly but we can’t be 100% sure so we would like a way to be able to continuously record pipeline pressure and download and review any transients that occur. These loggers could record for months at time and not see any transients so the key feature has to be the ability to record data, capture events based on some preset value and record over data if no event is detected to save storage space.
The Triton TRIDT-P is a pressure data logger specifically designed to capture transient events in pipelines, even those occurring in remote, unmanned locations. This makes it ideal for monitoring pipelines in situations where continuous supervision is impractical, such as oil and gas pipelines, water distribution networks, or chemical processing systems.
A key feature of the Triton TRIDT-P is its ability to operate in a low-power ‘sleep’ mode while continuously monitoring pressure. This conserves battery life, allowing for extended deployments in the field, often exceeding 5 years. When the logger detects a pressure change exceeding a preset threshold, it rapidly switches to a high-speed sampling mode, capturing data at a rate of up to 1000 readings per second. This ensures that the crucial details of transient events, such as pressure spikes or rapid fluctuations, are accurately recorded.
The logger utilizes an advanced data logging architecture that optimizes memory usage. It can store up to 1 million readings, organized into data files. To further enhance its data storage capacity, the Triton TRIDT-P employs an ‘over-sampling’ technique. This method involves recording data at a high rate but only saving the data points that deviate significantly from the previous reading. This approach is particularly effective in capturing transient events while minimizing memory consumption.
The Triton TRIDT-P is housed in a robust stainless steel enclosure, making it suitable for challenging industrial environments. Its waterproof and submersible design further enhances its durability and allows for deployment in a variety of locations, including those exposed to the elements or submerged in liquids.
For applications requiring continuous high-speed data acquisition, the Triton TRIDT-P can be connected to an external power supply. This allows the device to sample pressure continuously at 1KHz, ensuring that no critical data is missed. Data from the logger can be easily downloaded and analyzed using the provided software and a USB to IrDA communications cable. The software allows users to visualize pressure trends, identify anomalies, and generate reports for further analysis.
