Q1: Does the external clamp-type ultrasonic flowmeter need to be installed by cutting off the pipeline?
A: The external clamp-type does not require cutting off the pipeline or opening a weld. The sensor is directly clamped on the outer wall of the pipeline and can be installed without stopping the machine; Insertion type and pipe segment type require treatment of the pipeline.
Q2: Which media cannot be measured by ultrasonic flowmeter?
A: Mainly used for liquids that are clean or contain a small amount of bubbles; media containing a large number of bubbles, solid particles, and high-concentration mud will seriously weaken the ultrasonic signal, resulting in inaccurate measurement or even an inability to read.
Q3: Will pipeline material affect the measurement of ultrasonic flow meters?
A: Conventional materials such as steel pipes, stainless steel, PVC, and PE can be measured; Thick lining, severe corrosion of pipelines, and hollowing of pipeline interlayers can attenuate signals, and pipeline parameters need to be confirmed in advance.
Q4: Do ultrasonic flow meters have requirements for installing straight pipe sections?
A: There are requirements, generally requiring 10 times the pipe diameter upstream and 5 times the pipe diameter downstream; Flow field disturbances may occur near elbows, valves, and pump bodies. It is recommended to avoid installing at these locations as much as possible to ensure measurement accuracy.
