The vortex flowmeter configuration is composed of a sensor and a converter. The sensor includes a vortex generator(Baffle fluid), detection element, meter body, etc. The converter includes a preamplifier, filter Shaping circuit, D/A conversion circuit, output interface circuit, terminal, bracket, and protective cover, etc. The vortex generator is the main component of the detector.
It is related to the flow characteristics of the meter (meter coefficient, Linearity, range, etc.) are related to resistance characteristics (pressure loss), and the requirements for it are as follows.
- It can control the vortex to separate synchronously in the direction of the axis of the vortex generator;
- In a wide range of Reynolds number, there is a stable vortex separation point to maintain a constant Straw Hal number;
- A strong vortex street can be generated, and the signal-to-noise ratio of the signal is high;
- Simple shape and structure, convenient for processing and standardization of geometric parameters, and various detection elements installation and combination;
- The material should meet the requirements of fluid properties, corrosion resistance, abrasion resistance, and temperature change resistance;
- The natural frequency is outside the frequency band of the vortex signal.
