What are the main differences between vortex flowmeters and differential pressure flowmeters when measuring gas flow? Thanks for the advice from that expert! ! !
Vortex flow meters are primarily used for measuring the flow rate of fluids in industrial pipelines, including various media such as gases, liquids, and vapors. It is characterized by low pressure loss, a wide measurement range, and high accuracy; when measuring volumetric flow rate under operating conditions, it is hardly affected by parameters such as fluid density, pressure, temperature, and viscosity. There are no moving mechanical parts, thus it offers high reliability and requires minimal maintenance. The instrument parameters can remain stable over the long term. This instrument uses piezoelectric stress sensors, offering high reliability, and can operate within a working temperature range of -20°C to +250°C. It provides both analog standard signals and digital pulse signals for output. The differential pressure flow meter calculates the differential pressure generated as fluid passes through the orifice, and uses this value to determine the flow rate. The signal lines transmit electrical signals, which are generally generated on-site using pressure transmitters or differential pressure transmitters. These electrical signals are then transmitted through the signal lines to the flow integrator, thereby allowing the flow rate of the fluid to be calculated.
The measurement accuracy also varies; the accuracy of vortex flow meters is higher than that of differential pressure sensors
I’m sending you the specific working principle of related flowmeters, equipment selection guidelines, and installation precautions! ! !
The difference between a vortex flow meter and a differential pressure flow meter lies in their principles of operation; a vortex flow meter measures by determining the size of the vortices generated as fluid passes through the measuring device.
