The portables line from Panametrics, a Baker Hughes business, offers both ultrasonic liquid and gas clamp-on flow meters: The TransPort PT878GC for gas; and the TransPort PT900 for liquid. These ultrasonic flow meters utilize ultrasound to measure the velocity of a given fluid or gas - also known as "flow" - and are used in a wide variety of fluid and gas applications, from wastewater and various fuels to natural gas and compressed air.
These meters attach to pipe fixtures to measure the flow within the pipe. Quick installation and meter readings enable our users to continue their process without having to shut down. The meter’s portability allows the device to move to numerous measurement locations, making it easy to spot-check the flow, verify the flow meter, or temporarily install the device.

TransPort® PT878GC
The TransPort PT878 portable gas flow meter is a complete ultrasonic flow metering system for measuring most gases including: Natural gas, compressed air, fuel gases, erosive and corrosive gases, toxic gases, high-purity gases and air separation gases.
This flow meter can be installed in just minutes without needing to shut down, thus avoiding costly downtime. This ultrasonic technology works with gases at high or low pressure in pipes made of metal and most other materials.
The PT900 is portable, simple to use, accurate, and fast. It’s easy for you to move it from location to location and task to task, so you can get more out of every minute of your day. And since it clamps onto the pipe exterior, there’s no need to cut into the pipe or stop the process while taking measurements.
