Introduction - Vortex Flow Meter
The vortex flow meter is an advanced flow measurement device designed to measure the flow rate of various fluids, including liquids, gases, and steam. The vortex transmitter works by detecting vortices that form when fluid flows past a bluff body—a stationary element placed within the flow path. These vortices create alternating low- and high-pressure zones downstream, resulting in pressure fluctuations. A sensor inside the flow meter detects these pressure fluctuations and converts them into a frequency signal that reflects the flow rate.
In a specialized application like the LPG flow meter, the vortex flow meter’s sensor and transmitter work in perfect tandem to accommodate the unique properties of Liquefied Petroleum Gas (LPG). The piezoelectric sensor accurately detects the pressure fluctuations created by vortices as LPG passes the bluff body, ensuring stable and reliable readings even under variable flow conditions. The vortex transmitter then processes the piezoelectric signals into a precise, linear output that can be easily integrated into a process control system.
This robust design offers advantages such as low maintenance, high durability, and suitability for extreme temperatures and pressures, making vortex flow meters highly valued in industries like power generation, oil and gas, chemical processing, and HVAC. By providing accurate, real-time flow measurements, the vortex flow meter supports energy-efficient operations, safety monitoring, and optimal control over critical industrial processes.
Features
The vortex flow meter features a straightforward and durable design, simplifying installation and maintenance. It removes the need for impulse piping and a three-valve manifold, minimizing the risks of leakage, blockages, and freezing.
In terms of measurement precision, it achieves high accuracy, typically within ±(1 to 1.5)% of reading, making it suitable for applications requiring reliable data.
The display provides simultaneous readings of both instantaneous flow rate and cumulative flow, eliminating the need for alternating displays.
Engineered with a rational structure, the meter supports a broad dynamic measurement range and maintains minimal pressure loss, optimizing performance across varying flow conditions.
