Vortex Flow Meter

Vortex flow meters are based on the Karman vortex street theory. They use piezoelectric crystals to detect the vortex frequency generated when fluid passes through a triangular prism inside a pipe, thereby measuring the fluid flow rate.

Vortex flow meter can measure liquids, general gases, saturated steam, superheated steam, etc., and are widely used in industries such as petroleum, chemical, light industry, and power heating.

Features

  • 1. Simple structure, no moving wear parts
  • 2. High measurement accuracy, high reliability, no on-site commissioning
  • 3. The flow signal can be transmitted over long distances and can be networked with a computer for centralised management
  • 4. Amplification board adopts unique design, common for gas and liquid.

Installation Of Vortex Flow Meters

  • The sensor should be installed in the horizontal, vertical, inclined (liquid flow direction from the bottom to up) on the same pipe as its diameter. Upstream and downstream of the sensor should be configured with a certain length of straight pipe section, the length of which should meet the requirements of 15-20D for the front straight pipe section and 5-10D for the rear straight pipe section.
  • The pipeline near the installation of the liquid sensor should be filled with the measured liquid.
  • The sensor should avoid being installed in a pipe with strong mechanical vibrations.
  • Straight section of the inner diameter as far as possible with the sensor diameter, if not the same, should be slightly larger than the sensor diameter of the pipe, the error should be < 3%, and not more than 5 mm.
  • When the measured medium contains more impurities, a filter should be installed outside the required length of the straight pipe section upstream of the sensor The sensor should be installed to avoid strong electromagnetic field interference, small space and inconvenient maintenance occasions.
