Industrial Applications of PC10D Differential Pressure Sensor in Venturi and Vortex Flow Meters

From: Issued date 2025.08.29 Back


Accurate flow measurement is fundamental for industries that depend on controlled processes, energy efficiency, and compliance with regulations. Venturi flow meters and vortex flow meters are two of the most widely used devices for fluid flow monitoring. At the heart of these systems lies the differential pressure sensor, which converts pressure changes into electrical signals.

The PC10D piezoresistive silicon differential pressure sensor, with its robust stainless-steel construction, wide temperature compensation, and high static pressure resistance, is an excellent choice for both Venturi and vortex applications.

Working Principles of Venturi and Vortex Flow Meters

Flow Meter TypeWorking PrincipleRole of PC10D Differential Pressure Sensor
Venturi MeterMeasures flow by detecting pressure drop between the wide inlet and narrow throat, based on Bernoulli’s principle.PC10D measures differential pressure across the Venturi tube to calculate flow rate.
Vortex MeterA bluff body in the flow path creates vortices at a frequency proportional to flow rate. Pressure fluctuations are sensed.PC10D detects differential pressure variations caused by vortex shedding, enabling accurate flow monitoring.
