VPHR: Patented Technology Redefining Portable Hydrotest Recording

Traditional hydrotest recording has long been a cumbersome aspect of pipeline and pressure vessel integrity testing. Bulky chart recorders require external power, extensive calibration, and significant expertise to operate. At AI Connects Engineering, we developed the Very Portable Hydrotest Recorder (VPHR) to eliminate these barriers entirely.

VPHR Components

The VPHR system requires only three simple components:

• Pressure Transmitter: Configurable for any specific range of pressure
• Interface Driver: Links transmitter to PC via USB, WiFi, Bluetooth, or RF
• Windows Laptop: With pre-installed VPHR software

VPHR Special Features

• No external power supply needed — runs entirely from laptop battery, making it truly portable
• Live pressure capture — real-time data via serial connection to pressure transducer
• Parallel temperature recording — ambient temperature recorded with separate pen and range on chart
• No VPHR calibration needed — only the transmitter requires periodic calibration
• User-friendly controls — intuitive parameter settings for various pressure ranges
• Flexible duration monitoring — radar chart capable of monitoring any duration (1hr, 4hr, 36hr and beyond)
• Auto-ranging display — automatically adjusts to record any pressure range comprehensively
• Complete documentation — test duration, start time, stop time, and date clearly presented
• Connection status indicator — online indicator blinks to confirm communication linkage
• Instantaneous capture — sudden pressure drops (in milliseconds) are recorded
• Direct PDF output — completed records print to PDF immediately

Traditional Hydrotest Recorder Problems

The VPHR was designed to solve the fundamental problems with traditional hydrotest recorders:

• Bulky and not convenient to carry around
• Needs external AC power supply to drive operation
• Needs significant knowledge to set up for hydrotest
• Expensive and difficult to maintain
• Intensive calibration needed before each hydrotest
