As a flow measuring instrument, vortex flow meter has been used more and more in recent years,which greatly facilitates the supporting application of customers' computers and other digital systems and greatly reduces the application difficulty. Therefore, vortex flow meter has become the first choice of many enterprises.

In order to ensure the long-term uninterrupted operation of the vortex flow meter, the protection and maintenance of the vortex flow meter is quite important. The following is to introduce the protection methods in the daily use of the vortex flow meter:

Maintenance of vortex flow meter:

1. Timing cleaning, probe is an important structure of flow meter,if the probe detection hole is blocked, it may be wrapped by other objects,which will affect the normal measurement and lead to inaccurate results.

2. Moisture-proof treatment. Most probes are not moisture-proof,if the operating environment is humid, or there is no drying after cleaning, the function of the flow meter will be affected to a certain extent, resulting in poor operation.

3. Check regularly, the use of flow meter to reduce external disturbance as far as possible;Strictly check the grounding and shielding status of flow meter to ensure the accuracy of flow meter measurement.

Verification and calibration of vortex flow meter:

In order to ensure the accuracy and stability of measurement, it is necessary to calibrate or calibrate the flow meter in a period of time.Calibration needs to be sent to the measurement verification unit of the government. Calibration can be outsourced or operated by itself. A higher level of flow standard equipment can be used to calibrate the vortex flow meter.

Routine protection of vortex flow meters:

1. Routine protection of flow meter operation, protection of flow meter lining, and reduction of oil contact, to prevent impact on the insulation lining of flow meter.And prevent hard damage to surface finish.

2. There are very important components inside the flow meter to prevent oscillations，if violent oscillation occurs, internal deformation or cracking will occur.And prevent the inflow of corrosive liquids.
