At present condition of enterprise often use gas flowmeter are precession vortex flowmeter, turbine flowmeter, vortex flowmeter, orifice flow meter, power meter, V cone flowmeter, metal tube flow meter, delta, flow meter, etc. The precession vortex flow sensor is widely used in petroleum, chemical industry, electric power, metallurgy, urban gas supply, etc all kinds of gas flow measurement sensors, the proper use of precession vortex flow sensor should follow the following five requirements, so as to ensure the accuracy of measurement.

1, the right selection

Vortex precession flowmeter is widely applied in industries such as natural gas, coal gas, stable performance, accurate measurement, convenient installation, should choose precession vortex flowmeter in the established case, followed by the selection of flow sensor specifications and its supporting element is crucial. In a word, choose the right to use well. Therefore, in the process of selection should grasp two basic principles; Namely: to ensure the use of precision, to ensure production safety. To do this, we must to carry out the selection of the three parameters, namely the immediate and long-term maximum, minimum and the commonly used transient flow, the design of the measured medium pressure and work pressure.

2, calibration before use

On the one hand, given the current on-site verification for this kind of flow sensor in this or that kind of difficulties. In addition, if the intent of the purchase is ready to apply the this kind of flow sensor to the more important measurement occasions, such as heavy traffic trade dispute of measurement or prominent measurement point, and use the site also does not have the flow online calibration conditions, so in this case, with only when buying a paper factory qualified certification provided by the manufacturer easily determine all flow sensor performance is qualified, it is too early. Therefore, in order to ensure the flow sensor in the future work in the process of the measurement result is reliable and accurate, it is necessary before the formal installation flow sensor to have the detection capability and qualification of the department for a full flow within the scope of the system verification.

3, do a good job in installation process

Although this kind of flow sensor installation and use on the special requirements of environment is not too much, but any kind of flow measurement instrument has such a kind of common, that is as far as possible to avoid vibration and high temperature environment as flow interference components, keep straight pipe before and after the flow sensor inner surface smooth and flat, ensure to clean single-phase fluid measured medium, etc.

4, strengthen the management of late

Although precession vortex flowmeter has the characteristics of a variety of automatic disposal and micro power consumption, but still need to strengthen the management after put into operation. For example, in order to ensure the accuracy of the flow sensor to work for a long time, reliability, and it should be regular system calibration, transcribing header data, replace the medium parameters and not regularly check the battery status, check the flow coefficient of the sensor and the seal.

5, pay attention to the internal maintenance

If due to temperament dirt or other reasons to flow sensor measurement of cavity and its components in regular inspection or cleaning, so one thing you must pay special attention to: for the same specification of precession vortex flow sensor, the vortex occurred, the diversion and other core components are not interchangeable, otherwise, must be to calibrate the instrument measurement coefficient and the matching of the temperature and pressure sensor calibration system.
