1. Classification of Vortex Flow Meters

Vortex flow meters are mainly divided into two types: capacitive vortex flow meters and piezoelectric vortex flow meters. The specific introduction is as follows: Detection principle of capacitive vortex flow meters: The probe of the capacitive vortex flow sensor is composed of a pair of differential capacitors. When the fluid flows through the vortex generator, vortices are generated, and these vortex forces alternately act on both sides of the probe, causing a difference in the differential capacitance of the probe. This difference change is processed by an amplifier and converted into a flow electric pulse signal, thereby achieving measurement of fluid flow rate. Performance characteristics: Good anti vibration performance: The unique internal structure endows the probe with excellent anti vibration ability, which can effectively reduce the interference of external vibration on the measurement results and ensure the accuracy of the measurement. Measurable minimum flow rate: capable of measuring small flow rates, suitable for industrial scenarios that require high accuracy in flow measurement and have small flow rates. Excellent high temperature resistance: The substrate of the probe capacitor plate is made of imported ceramics and formed at a high temperature of over a thousand degrees, which enables it to work stably in high temperature environments and expands its application range. High reliability: The process and structural design of the core components are reasonable, which improves the reliability of the entire flowmeter and reduces the probability of failure. Outstanding intelligent features: The intelligent sensor has gas and liquid universality and can autom

atically track the passband without the need to adjust the entire bandwidth and sensitivity through potentiometers or toggle switches. At the same time, there is no zero drift phenomenon, and the range can be freely set, truly achieving on-site debugging free operation, greatly facilitating user use. In addition, the circuit has a suppression effect on different vibration frequencies, further enhancing its anti vibration performance. It also has a linearization function, which can make the measurement results of the lift reading more accurate. Detection principle of piezoelectric vortex flowmeter: Stress vortex flowmeter belongs to a type of velocity flowmeter, which is based on the Karman vortex theory. When the fluid passes through the triangular column inside the pipeline, vortices are generated, and piezoelectric crystals can detect the frequency changes caused by these vortices. By measuring this frequency, the flow rate of the fluid can be calculated. Performance characteristics: Simple and sturdy structure: The overall structural design is concise, the connections between components are firm, and there are no cumbersome moving and worn parts. This not only reduces manufacturing costs, but also improves the stability and reliability of the flowmeter. Long service life: Due to the absence of moving wear parts, the occurrence of malfunctions and damages caused by component wear is reduced, thereby extending the high service life of the flowmeter and reducing maintenance costs. High measurement accuracy: able to accurately measure the flow rate of fluids, meeting the requirements for flow measurement accuracy in industrial production. Wide range: It can measure a large flow range and is suitable for industrial scenari
