Watch the Portasonic® PRO Demonstration Video on ‘How to Measure Flow Rate with Flow Sensors’.

The Portasonic® PRO measures the flow rate of your liquid non-invasively and has a built-in software to convert your flow rates to pressure. The measured flow is accurate to 0.5% of the true value and the calculated pressure is accurate to 5% of internal pipe pressures.

Using non-invasive technology, our transit time flow meters have significant advantages against an inline flow meter by reducing installation cost, risk and downtime for your flow rate measurements.

We pride ourselves with the quality, reliability and accuracy of our instruments – all made in the UK. Our Ultrasonic Flow Meter range has been tested and calibrated at an ISO 17025 laboratory, meeting accuracies of +/- 0.5% of the true flow rate.
