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.
We would suggest the Triton event triggered high sampling rate pressure logger which has a data logging architecture that allows the device to sit silent consuming very little battery whilst monitoring the pressure and logging at slow interval periods, but because of the over sampling it can identify when a transient is occurring and switches to 1000 readings per second. You can also assign a threshold value so if the pressure peaks above this it switches to a faster mode.
