The intelligent vortex flowmeter is a speed flow meter based on the Karman vortex theory, which utilizes the natural vibration principle of fluid and is supported by piezoelectric crystals or differential capacitors as detection components. This product uses unique differential technology, combined with measures such as isolation, shielding, and filtering, to overcome the problems of similar products such as poor shock resistance, high noise, and disordered small signal data. It also adopts a unique new detection probe packaging technology and protective measures to ensure improve product reliability.
The product has three measurement modes: basic type, differential pressure type, and integrated temperature and pressure compensation type. The basic type measures a single working condition flow signal, the differential pressure compensation type directly measures mass flow, and the integrated temperature and pressure compensation type can measure temperature, pressure, and flow at the same time. The signal is compensated and outputs standard volume flow or mass flow. The product has two structural forms: pipeline type and plug-in type, which can be displayed on site or transmitted over long distances. Each type has high temperature, high pressure, anti-corrosion, explosion-proof and other specifications, and also has integral and split structures to adapt to different measurements. Media and installation environment.
This series has a series of advantages such as wide range ratio, high precision, convenient installation and maintenance, and wide media adaptability. It can be widely used in process measurement and energy-saving management of various low-viscosity liquids, other, steam and other single-phase fluids in petroleum, chemical, metallurgy, machinery, food, papermaking, medicine, urban pipeline heating, gas and other industries.
Principle of intelligent vortex flowmeter
Vortex flowmeter special equipment TS supervisory inspection certificate uses the Karman vortex principle for flow measurement. When a column is vertically inserted into the measuring tube, the fluid will naturally alternately generate regular vortices (as shown in the figure below) when passing through both sides of the column. This vortex array is called a Karman vortex street. When d/D=0.281, the released vortex is very stable.
