Vortex flow meter with Flange connection

A BX-6000-G Vortex flow meter is designed to measure liquids' flow rate by utilizing the vortex shedding principle. Here's an overview of the construction and key components of a vortex flow meter for liquid flow measurement:
 

Bluff Body or Shedding Element: The primary component is a bluff body inserted into the flow path. This obstruction causes the flowing liquid to create alternating vortices downstream. This element's shape and design significantly influence vortices' generation and stability.
 

Vortex Sensor: Sensors, often piezoelectric, strain gauge, or capacitive sensors, are strategically placed to detect the vortices formed behind the bluff body. These sensors convert the mechanical energy of the vortices into electrical signals.
 

Signal Processing Unit: The electrical signals from the vortex sensors are processed and conditioned by electronic circuits within the meter. The signals' frequency or amplitude corresponds to the liquid's flow rate. Signal processing ensures an accurate interpretation of the vortex signal.
 

Converter and Display: The processed signals are converted into flow rate measurements. This data is displayed on an output device, such as a digital display, an analog meter, or an interface that transmits the data to a control system or data logger.
 

Power Supply: The flow meter requires a power supply to operate the electronic components, sensors, and signal processing circuitry. This power supply could be battery-operated or sourced from the system where the flow meter is installed.
 

Housing and Enclosure: All the internal components are enclosed in robust and often waterproof housing to protect them from the measured liquid and environmental factors. The housing is designed to withstand the conditions of the intended operating environment.
 

Calibration Mechanism: Vortex flow meters require calibration to ensure accuracy. Some meters may include mechanisms or provisions for calibration adjustments to maintain precision over time or for different flow conditions.
 

Vortex flow meters are known for their reliability, accuracy, and ability to measure flow rates in various liquid applications. They are particularly useful in applications where the liquid contains minimal suspended solids or bubbles that could disrupt vortex formation, affecting measurement accuracy. Additionally, these meters are suitable for high and low flow rates, making them versatile in various industries such as chemical processing, water treatment, and oil and gas.
