Overview

Calculate Internal Pipe Pressure from External Flow

The Portasonic® CALCULATOR is the first instrument capable of determining the internal pressure within pipes, using non-invasive, external flow technology.  

This calculator is designed to operate alongside our Portasonic 2.FL0® Ultrasonic Flow Meter. The Portasonic is one of the world’s leading non-invasive flow meters and is an essential tool for a wide variety of maintenance and inspection needs.  

The Portasonic® CALCULATOR is designed as a supporting instrument. It uses an empirical equation derived from the laws of fluid dynamics to calculate the liquid pressure to within 5% accuracy. Our knowledge of the properties of 19+ different fluids and 23 different common pipe materials has enabled us to acquire a detailed understanding of the pressure required to drive different fluids at a variety of flow speeds. 

Why measure internal pipe pressure? 

The pressure in a pipe system must be closely monitored to ensure it does not exceed safe tolerances. Critically high pressures can lead to pipe failure, damage to property, and risk to personnel. The durability and safe functioning of pipes, pumps, and related equipment are also affected by pressure. Knowledge of the pressure in a pipe system is therefore important for ensuring that the flow is occurring as expected, in a safe and sustainable manner. 

Features 

  • Calculate quickly and easily using an intuitive touchscreen tablet

Frequently asked questions

Pressure gauges are invasive and costly to install in pre-existing systems. The Portasonic® CALCULATOR is ideal for obtaining hassle-free pressure measurements.
The pressure in a pipe varies from a maximum value at the input to a minimum value at the output. It is this pressure differential that drives the fluid through the pipe. The Portasonic® CALCULATOR calculates this maximum value based on the measured flow speed. Thus, the value obtained is the maximum pressure at any point in the pipe system, not including added complications such as valves.
The temperature of a fluid can affect its flow and pressure, which is why the Portasonic® CALCULATOR instructs the user to input the temperature. As long as the substance remains a fluid, the calculations remain valid over a temperature range of -50°C to 150°C. Accuracy, however, decreases with more extreme temperatures.
Yes, the instrument has inbuilt WiFi connectivity.
The battery can last for up to four days.
Excepting the following caveats, the calculated pressure is always accurate to within ±5%.This accuracy holds for clean pipes, free of internal corrosion and residue build-up. It is also valid for temperatures between 10°C and 30°C. Temperatures outside of these bounds will, for the most part, still yield results of a similar accuracy, but these are as yet unverified. Finally, some graded liquids are listed under a general name, for example, crude oil. These take median values for the liquid properties, which will not necessarily be accurate for all grades.
