Abstract: Gasunie has performed tests on two types of installation effects on multipath ultrasonic gas meters with a diameter of 500 mm. The effect of mildly wet flows was studied by injecting liquids in the gas flow and monitoring changes in signal and noise levels and in the meter error. It was concluded that small amounts of liquids do not affect the meter error, and that the meter itself can detect if signal to noise ratios are distorted so much that proper functioning is no longer possible.
