The unique clamp-on fixture design makes the installation very simple and no special skills or tools are required. Due to hot-tapped mounting of insertion transducers, there is no ultrasonic compound and coupling problem; Even though the transducers are inserted into pipe wall, they do not intrude into the flow, thus, do not generate disturbance or pressure drop to the flow. Comparing with clamp on flow meter, the insertion (wetted) type has the advantage of long-term stability and better accuracy. |
