Portasonic® CALCULATOR

New February 2021 

Handheld instrument, the world’s first capability to convert the fluid flow speed in a pipe measured by the Portasonic® and convert it to a reading of pressure.

This is the only instrument capable of determining the pressure required to drive fluids at a specified flow speed



Software on robust 7” provides the world’s first capability in calculating the pressure required to pump a liquid along a pipe that is travelling at the flow speed measured by the Portasonic®

This is the perfect product to save and report your flow and pressure results. Combine calculated pressure with readings from the Portasonic® 2.FL0 to verify measured flow speeds and rates against a fixed pressure gauge in the system.

  • The only instrument capable of determining the pressure of a liquid from the measured flow speed
  • Provides a non-invasive alternative to pressure gauges
