  • Page 12 Signal strength indicates the detected strength of the sonic signal in decibels (dB). Signal strength is indicated by numbers from typically -25.0 to +55.0. Normally, the stronger the signal strength detected the better and more reliable the flow measurement is, as well as the more stable the measurement value obtained. Adjust the transducer positioning to the best position, within limits and check to ensure that enough sonic coupling compound is applied during installation in order to obtain the maximum signal strength.
