This manual covers the operation, specifications, and features of the GE Sensing TransPort PT878 portable ultrasonic liquid flowmeter.
The GE Sensing TransPort PT878 is a self-contained, portable transit-time ultrasonic flowmeter designed for measuring liquid flow in various applications. It utilizes patented Correlation Transit-Time digital signal processing to ensure accurate measurements in difficult conditions, including liquids with entrained solids or gas bubbles and perfectly clean liquids where Doppler-type meters fail.
The device features a large backlit LCD display capable of alphanumeric and graphic formats, allowing users to view real-time data and trends. It includes a rechargeable battery pack for extended field use and supports multiple languages. Optional accessories include an energy measurement module with RTD temperature sensors and a pipe wall thickness gauge.
