DN15-DN1000 OEM Digital Display Stainless Steel Vortex Flow Meter Sensor High Accuracy Liquid Gas Effective Flow Measurement
1.Product Overview
The KVF200 vortex flow meter is a fluid oscillation-type flow instrument based on the Kármán Vortex Street principle. It calculates flow velocity and rate by measuring the alternating vortex shedding frequency generated downstream of a non-streamlined bluff body (vortex shedder). It features no moving parts, a wide turndown ratio, and broad media compatibility.
