    Through the latest 20 years ultrasonic measurement has proved the most long-term stable measuring principle for heat measurement. Both experience from ultrasonic meters in operation and repeated reliability tests carried out in Kamstrup’s accredited long-term test equipment as well as by AGFW in Germany have documented the long- term stability of ultrasonic meters.
