Smarter Pig Tracking, Blockage Detection, and Hydrotesting—All in One Platform

PipeServ from PipeSense streamlines critical pipeline operations with fast, accurate solutions for pig tracking, blockage detection, and hydrotest monitoring—reducing downtime, increasing safety, and eliminating uncertainty.

  • PipeTrack delivers real-time pig tracking without field trackers, even in static conditions. Its ultra-high-frequency pressure sampling confirms pig location within 4–6 hours—no extra hardware required.

  • PipeScan quickly identifies and locates blockages like hydrate plugs, wax, or debris using the same system, making it easy to pivot from tracking to troubleshooting.

  • PipeTest redefines hydrotesting with real-time pressure and temperature data, including a live dashboard and leak detection tied directly to temperature-corrected thresholds—no more guesswork or retesting.

With a user-friendly dashboard, minimal setup, and compatibility across all pipeline diameters, PipeServ simplifies operations while helping you stay compliant and proactive.

When safety and performance matter, PipeServ delivers.

Eliminate the Guesswork: Next-Generation Leak Detection with PipeGuard

PipeGuard by PipeSense delivers real-time, AI-powered leak detection with 99.998% accuracy—eliminating false positives and locating leaks within 20–50 feet. Unlike traditional systems that delay response or generate costly false alarms, PipeGuard uses ultra-high-frequency pressure sampling (1,000 readings per second) and edge-based machine learning to instantly identify and verify anomalies.

Designed for seamless integration with existing SCADA and DCS infrastructure, PipeGuard operates autonomously 24/7, with no recalibration needed—even across liquids, gases, multi-phase flows, or remote sites. It meets PHMSA Valve Rule standards and is API RP 1130 compliant, ensuring regulatory peace of mind.

From solar battery power and Starlink readiness to secure text, email, and web alerts, PipeGuard is leak detection reimagined for modern operators.

After 50 Years of Nonsense, Hydrotesting is Finally Demystified

PipeSense Continues to Raise Bar for Accuracy, Accountability With Market’s Only Real-Time Hydrotesting Dashboard

HOUSTONJune 24, 2025 /PRNewswire/ — PipeSense, the leak detection company whose ultra-high-frequency pressure sampling and advanced AI brought common sense to hydrotesting, has just launched the market’s only real-time, comprehensive hydrotest dashboard. PipeTest HydroView helps pipeline operators clearly differentiate between leaks and temperature changes during a hydrotest, bringing robust data visibility to a service notorious for its challenges, and providing them the ability to approve a test real-time.

Until the launch of PipeSense’s PipeTest, hydrotesting methods had been largely unchanged for more than 50 years.

Now available to PipeSense customers, the HydroView Dashboard is the latest update to PipeSense’s PipeTest service for monitoring pressure and temperature during all stages of a hydrostatic pressure test. With the dashboard launch, PipeSense becomes the only company offering real-time leak detection and location during hydrotests, said Stuart Mitchell, PipeSense CTO.

“PipeTest HydroView will allow our clients to better understand the progress of a hydrotest in real-time from anywhere in the world, while improving efficiency, accuracy and overall confidence in the test result,” said Mitchell. “Our clients will now have certainty with their hydrotest.”

The dashboard provides hydrotest supervisors, inspectors and engineers with a number of critical real-time data points, including rolling pressure windows and trends at 15 minutes and one hour, ground temperature, temperature-corrected pressure floor and the location of newly-formed detected leaks. In doing so, PipeTest HydroView helps customers eliminate time-intensive blown tests, reduce test approval timelines and know for certain that the test results are accurate.

Key features include:

  • Real-time pressure trends and data insights
  • Real-time temperature corrected pressure floor for the test
  • True correlation between temperature change and test pressure to correctly identify very small leaks
  • Real-time leak location for newly formed detected leaks

With a streamlined interface and rich data visualizations, PipeTest HydroView is designed to help busy midstream professionals get the accurate, data-driven results they need — minus the uncertainty of past hydrotesting methods, Mitchell said.

Until the launch of PipeSense’s PipeTest service, hydrotesting methods for the midstream industry had been largely unchanged for more than 50 years.
