高精度不锈钢涡街流量计

Working Principle

High accuracy stainless steel vortex flowmeter consists of two parts: flow sensor and signal processor. The core part of the flow sensor is a mechanical part called “vortex vane”, which can be made of stainless steel and other materials. When the fluid with a sufficiently large flow rate perpendicular to the direction of fluid flow through the vortex vane, the vortex will be behind the vortex vane along two parallel straight lines to produce a neatly arranged, opposite direction of the vortex column. The number of these vortex columns (i.e., vortex frequency) is directly proportional to the fluid flow rate. The flow sensor calculates the fluid flow by acquiring the vortex signals on the vortex vane, while the signal processor analyzes these signals and outputs the results in the form of digital signals, thus realizing real-time monitoring and control of the flow.

• 4. Conveying: In pipeline conveying, it is used for controlling, distributing and scheduling the fluid medium to ensure the safe operation and economic accounting of pipeline conveying.

High accuracy stainless steel vortex flowmeter selection

When selecting and using a high accuracy stainless steel vortex flowmeter, you need to pay attention to the following points:

• 1. Working conditions: according to the nature of the measurement medium, 温度, pressure and other working conditions to choose the appropriate vortex flowmeter models and specifications.
• 2. Installation: Install the vortex flowmeter correctly according to the instructions to ensure its measurement accuracy and stability.
• 3. Maintenance: Regular maintenance of the vortex flowmeter, check its operating status and measurement accuracy to ensure its long-term stable operation.
• 4. Seismic performance: Because the vortex flowmeter’s seismic performance is poor, so in the use of the process need to pay attention to avoid external vibration on its impact.
