Insertion Ultrasonic BTU Thermal Flowmeter Hot-Tapped Installation Liquid measure



The Insertion Ultrasonic Flow Meter provides abundant capabilities for accurate liquid flow measurement from outside of a pipe. Insertion Ultrasonic Flowmeter utilizes state-of-the-art technologies on ultrasonic transmission /receiving, digital signal processing and transit-time measurement. The proprietary signal quality tracking and self-adapting technologies allow system to optimally adapt to different pipe materials automatically. 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. The insertion (wetted) type has the advantage of long-term stability and better accuracy.
