In Coltraco, we pride ourselves on our UK-made instruments’ quality, reliability, and accuracy, including ultrasonic flow meters. Each ultrasonic flow meter we’ve produced has been tested and calibrated at an ISO 17025 laboratory, meeting an accuracy of +/- 0.5% of the true flow rate. Using non-invasive technology, our transit time flow meters have significant advantages over inline flow meters by reducing installation cost, risk, and downtime for your flow rate measurements
The Permaflow® is a fixed, clamp-on, ultrasonic transit time flow and heat meter that is non-invasive for measuring the flow rates of liquids containing less than 10% of gas/solid contents. It is mains powered, designed for 24/7 monitoring and is accurate to +/- 0.5% of measured value under ideal conditions.
