Vortex flowmeters are used in numerous branches of industry to measure the volume flow of liquids, gases and steam. Applications in the chemicals and petrochemicals industries, for example, in power generation and heat-supply systems involve widely differing fluids: saturated steam, superheated steam, compressed air, nitrogen, liquefied gases, flue gases, carbon dioxide, fully demineralized water, solvents, heat-transfer oils, boiler feedwater, condensate, etcBenefits :
Universally suitable for measuring liquids, gases and steam
Largely unaffected by changes in pressure, density, temperature and viscosity
High long-term stability: no zero-point drift and lifetime K-factor
Large turndown of typically 10:1 to 30:1 for gas/steam, or up to 40:1 for liquids
Wide temperature range: –200 to +400 °C (+450 °C on demand)
f56 metal cone variable area flowmetersare used for measure instantaneous and accumulated flow rate of liquid, gas and steam in closed pipelines. It is suitable for metering flow value on site or electronic remote.the measuring principle is based on the hydrodynamic effects,this makes float moving from bottom to top in vertical pipe. As the displacement of float is in related to flow rate, which can be read from the indicator by means of the magnetic drive system in non-contact form . Also, flowmeters output electrical signal (4-20)ma / hart communication protocol with high / low limit warning switches/integrating flow pcb broad can be configured.
