    Why would I use the Portasonic® CALCULATOR instead of a pressure gauge?

    Pressure gauges are invasive and costly to install in pre-existing systems. The Portasonic® CALCULATOR is ideal for obtaining hassle-free pressure measurements. 

    Does the Portasonic® CALCULATOR measure the pressure throughout the whole length of the pipe?

    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. 

    Does the temperature matter?

    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. 

    Does the Portasonic® CALCULATOR connect to WiFi?

    Yes, the instrument has inbuilt WiFi connectivity. 

    What is the battery life?

    The battery can last for up to four days. 

    What is the accuracy of the Portasonic® CALCULATOR?

    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. 


    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.

    • Portasonic® CALCULATOR is a non-invasive alternative to pressure gauges, which may require costly installation in difficult to reach places.
    • It is, therefore, the only way of quantifying the pressure in any system where the flow speed is known, but there is no apparatus installed for pressure measurement.
    • It can be used with all of your pipes to store records, thereby creating a centralised database of all past tests – perfect for ensuring reliable, traceable reporting.
