GE PT878 Portable Ultrasonic Gas Flow Meter

GE TransPort PT878 Portable Ultrasonic Liquid Flow Meter

Supports multiple languages

The TransPort PT878 flowmeter system integrates many functions in a lightweight portable case.

Its built-in data logger can store over 100000 data points and up to 32 on-site parameters. You can choose to add an ultrasonic thickness sensor. Temperature sensors can be used to measure energy flow. Rechargeable batteries can support 6 to 8 hours of continuous remote work. This table has a built-in infrared interface to transfer data, parameters, and other files to your PC. The sealed casing reaches IP67 protection level, which can protect PT878 from accidental falling into water.

Performance and Advantages

PT878 is currently one of the most powerful portable liquid flow meters. It can measure the flow rate in plastic, metal, or concrete pipes without damaging the pipe wall, so it will not cause pressure loss, leakage, or pollution. The cross-correlation time difference signal protected by algorithms is different from other flow meters, allowing PT878 to measure the flow rate from ultrapure water to untreated sewage and mud.

The PT878 flowmeter can only support English or English and one other language. The supported languages are Dutch, Castilian, French, German, Italian, Japanese, Portuguese, Russian, Spanish, and Swedish.
