SIGNAL QUALITY of TF1100-EP portable transit time ultrasonic flow meter

Quality is indicated as the Q value in the instrument. A higher Q value would mean a higher Signal and Noise Ratio (short for SNR), and accordingly a higher degree of accuracy would be achieved. Under normal pipe condition, the Q value is in the range 60.0-90.0, the higher the better.
Causation for a lower Q value could be:
1. Interference of other instruments and devices such as a powerful transverter working nearby. Try to relocate the flow meter to a new place where the interference can be reduced.
2. Bad sonic coupling for the transducers with the pipe. Try to apply more coupler or clean the surface, etc.
3. Pipes are difficult to be measured. Relocation is recommended.
