pulsPG

Monitors moisture and locates the fault

The pulsPG is a localising monitoring module that uses TDR (Time Domain Reflectometry, pulse echometer) technology. It is used to monitor district heating and district cooling pipes and other pipelines, e.g. oil. The unit consists of a main unit and 1–8 external measurement modules, and the main unit can hold a maximum of two TDR measurement cards.

In addition to insulation resistance and galvanic voltage, the pulsPG measures the status of the pipe: the deviation of the TDR curve from the reference and, in case of damage, the distance to the fault. When a fault occurs, a TDR curve is saved for analysis.

The pulsPG alarms when the TDR curve deviates from the reference or the previous curve by more than the set limit, for example 0.5%. It also calculates a status code that tells the type of fault, and synchronises curves and readings to both the monitoring system and Stateview’s S-Plan. The Equalizer function shows small changes along the pipe over time. It helps locate moisture that reaches the leakage wire only locally, for example after heavy rain or in a pit.

• Measuring modules are connected directly to the pipe without external cables.
• With external measurement cards the main unit also collects data from separate buildings and chambers.
• You pay only for the equipment you need, and the system is easy to adapt when the pipe network changes.
• Monitoring and alarms via the monitoring system.
• Proven and widely used TDR technology based on the Stateview measurement card. Fully compatible with Stateview System II.
• As an option, the module runs the same analyses as the SM20 handheld instrument and saves data in the same databases, so an expert can support the analysis remotely.
