Compact and portable transit time ultrasonic flow meter

The GE Panametrics TransPort PT878 ultrasonic flow meter is a highly versatile, self-contained, portable transit-time system with options and accessories to meet all your liquid flow measurement needs. Its compact size; lightweight, rechargeable internal battery pack; and universal power supply charger make it the ideal go-anywhere flow meter.

Accurate with Two-Phase and Perfectly Clean Liquids

The TransPort PT878’s patented Correlation Transit-Time™ digital signal processing (DSP) technique greatly increases its signal-to-noise ratio for accurate, drift-free flow measurement in liquids that contain a second phase of entrained solids or gas bubbles. The Panametrics PT878 operates in these and other difficult applications where conventional transit time flow meters fail.

The TransPort PT878 flow meter also accurately measures flow rate in perfectly clean liquids containing no “scatterers,” where Doppler flow meters cannot work. The PT878 is suited for all standard transit time applications, plus many that would prevent other transit time flow meters from working.

Quick and Easy to Use

It’s possible to make your first flow measurement within minutes of opening the box — the TransPort PT878 is that easy to use. Simply input the site parameters, clamp the transducers onto the pipe, adjust the spacing, and you’re under way. No ancillary equipment is needed, and there’s no need to break into the pipeline. An experienced user can make scores of different measurements in a single day. The TransPort PT878 flow meter is ideal for all kinds of flow survey work.

Flow Transducers and Clamping Fixtures

Using clamp-on transducers, the TransPort PT878 flow meter measures flow rate through metal, plastic, or even concrete-lined pipes, without penetrating the pipe wall. From ultra-pure water to corrosive and toxic liquids, the TransPort PT878 flow meter ensures non-contaminating, leak-free measurement with drift-free accuracy. The PT878 has no moving parts to wear or orifices to clog. It can’t be fouled, and it requires no routine maintenance.

A wide variety of transducers are available with different operating frequencies, materials of construction, operating temperatures, and sizes to meet the requirements of rugged industrial environments.

To hold clamp-on transducers in contact with the pipe, a variety of clamping fixtures are available to accommodate different pipe and transducer sizes. These fixtures use a variety of attachment methods including chain, metal strap, Velcro® strap, and magnetic clamps.
