D8800 Series vortex precession flow meter
D8800 Series vortex precession flow meter, vortex precession flow meter,D8800 flow meter
Introduction
This type of meter also operates by detecting vortices. However, in this device, the fluid is forced into a swirl condition by swirl-producing vanes, or swirl blades. The center of the vortex becomes displaced from the meter centerline and follows a helical path (precession) as it moves downstream through an enlargement. This precession causes fluctuations in fluid pressure and velocity. A sensor placed downstream from the swirl blades detects and measures the frequency of the precession. This frequency is linearly proportional to flow rate.
Vortex precession flowmeter for measuring volumetric flow, temperature, pressure, density, and mass flow using a single meter
Measures most gases, liquids and steam without the need to recalibrate
Cost effective, accurate and reliable meter for volumetric and mass flow measurement
Remote monitoring and integration to DCS using HARTand Modbus communication protocols
Significant cost savings through reduced
installation costs, wiring runs and services support.
Ideal for high temperature and high velocity steam
Power Generation steam applications
Industrial HVAC, district energy management
Commercial building, campus and facility energy management
Oil & gas allocation of natural gas
Petrochemical mass balancing, reaction processes heating
Pana Flows multi variable design consists of a vortex shedding
velocity sensor, an RTD temperature sensor and a solid-state
pressure transducer that measures the mass flow rate of steam, gases and liquids. The Pana Flow vortex flow meter measures velocity, temperature and pressure in the same location, which provides more accurate process measurement. Integrating pressure and temperature simplifies system complexity and helps minimize initial capital costs, as well as reduce the installation costs. A wide range of options and meter configurations are available to meet your specific application requirements
