How to ensure the accuracy of the turbine flowmeter
measurement of turbine flowmeter is widely used in petroleum, chemical industry, electric power, metallurgy, urban gas supply, etc all kinds of gas flow measurement sensors and to the proper use of turbine flowmeter should follow the following five.
More flow meter manufacturers choose model price quote you are welcome to inquire, here is how to ensure the accuracy of the turbine meter scale measurement details.
How to ensure the accuracy of the turbine flowmeter measurement of turbine flowmeter is widely used in petroleum, chemical industry, electric power, metallurgy, urban gas supply, etc all kinds of gas flow measurement sensors, proper use of turbine flowmeter should follow the following five requirements, so as to ensure the accuracy of measurement.
A, attaches great importance to the instrument selection under the condition of the already selected flow sensor type, 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 zui, zui small and common transient flow, the design of the measured medium pressure and work pressure.
Second, the calibration method prior to 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.
Three, do well the process though this kind of flow sensor installation process of installation and use of the special requirements of environment is not too much, but any kind of flow measurement instrument has such a 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.
Four although late, strengthening the management of the flow sensor has a variety of automatic disposal function and the characteristics of 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.
Five, pay attention to the internal maintenance if due to temperament dirt or other reasons need 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 specifications of the turbine flowmeter, the vortex occurred, diversion and other core components are not interchangeable, otherwise, must be to calibrate the instrument measuring coefficient are equipped with temperature and pressure sensor and system calibration.
Flow sensor selection, calibration, installation, management and internal maintenance requirements if grasp well the five, sensor after use will reduce a lot of problems, it is particularly important for the continuous production manufacturer.
Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
