  • Fluid and Material Knowledge: Extensive knowledge of 19+ different fluids and 23 common pipe materials ensures accurate pressure calculations across various scenarios.




Advantages of Non-Invasive Ultrasonic Flow Measurement and Pressure Monitoring

Choose non-invasive ultrasonic transit time technology over inline flow meters for its versatility and cost-effectiveness.

  • The clamp-on, portable nature eliminates installation costs and downtime, as it doesn’t require drilling into pipes.
  • With no contact with the fluid, there’s no risk of pressure loss or damage to the flowmeter, ensuring a longer lifespan and lower maintenance costs compared to inline meters.
  • Monitoring internal pipe gauge pressure is crucial to prevent pipe failure, property damage, and risks to personnel.

Frequently asked questions

Pressure gauges are invasive and costly to install in pre-existing systems which are not already pre-installed with one. The Portasonic® PRO can assist by measuring the flow rate of your liquid and obtaining hassle-free pressure measurements at the same time.
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® PRO 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® PRO 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.
The flow rate measurement of the Portasonic® PRO is accurate to within 1%, under ideal conditions that is verified independently by an external ISO 17025 laboratory. 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.
