How can an ultrasonic flowmeter be used when the flow rate is insufficient? Knowing these three points is enough!
Three solutions for using ultrasonic flow meters when the flow rate is not full: In flow measurement, the full tube state is one of the basic conditions to ensure measurement accuracy, and ultrasonic flow meters are no exception.. However, in practical applications, in many working conditions, the pipeline liquid is not in a full state, but flow measurement must be carried out. In response to this situation, there are three effective solutions:
First, changing the diameter of the pipeline. Solution: If the pipeline where the measurement was originally intended is thicker and the liquid inside the pipeline is often in a non full state, it can be considered to replace the pipeline with a smaller diameter pipeline. By reducing the diameter of the pipeline, the pressure of the liquid inside the pipeline can be increased, making it easier to reach the full pipe state. Then, install an external clamp type ultrasonic flowmeter on the transformed pipeline for flow measurement. Attention: When changing the diameter of the pipeline, it is necessary to ensure that the material, wall thickness, and other parameters of the new pipeline match the original pipeline to avoid adverse effects on fluid flow. At the same time, it is necessary to recalibrate the flow meter to ensure the accuracy of the measurement results.
2. Upstream booster pump solution: If conditions permit, a pipeline type booster pump can be installed upstream of the ultrasonic flowmeter.
. A booster pump can increase the flow rate and pressure of the liquid in the pipeline, enabling it to reach full capacity in a short peri
3. Solution for changing pipeline flow direction: External clamping microfiber combined with acoustic flowmeter can be used not only on horizontal pipelines, but also on vertical pipelines.
. If the site conditions permit, it is possible to consider modifying the flow direction of the pipeline by making it into a "X" shape or similar shape, and installing the flow meter on the vertical pipeline where the liquid flows upward. In this way, due to the effect of gravity, the liquid inside the pipeline will remain in a fully filled state, with only a change in flow velocity. Attention: When changing the flow direction of the pipeline, it is necessary to ensure that the bending radius of the pipeline is large enough to avoid excessive resistance and eddies to the fluid flow. At the same time, it is necessary to consider the support and fixation of the pipeline to ensure its stability and safety. In addition, when installing a flowmeter on a vertical pipeline, attention should be paid to preventing direct impact and corrosion of the flowmeter by liquids.
