Raw gas ultrasonic flow meter
Thread Content
When using an ultrasonic flow meter to measure the flow rate in a DN80 natural gas feed pipeline, is an external-mounted type or a in-line type generally used?
If it is a DN80 natural gas feed pipeline, an ultrasonic flow meter can be used for the pipeline. The engineering flow coefficient can range from DN40 to DN80, with an accuracy guaranteed at level 1.0. Its feature is a large range, which can reach 1:400. The special features include the ability to measure very low flow rates, a function for detecting pipe leaks, and zero pressure loss.
External flow meters have lower accuracy compared to those installed in pipelines
