How to use flowmeter correctly

In the case of instrument selection, which has been selected for the type of instrument (i.e., intelligent target flowmeter), the selection of instrument specification and its supporting elements is very important. In a word, choose well to use. Therefore, two basic principles should be grasped in the selection process. Namely: one must ensure the use of accuracy, two must 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 instantaneous flow (mainly for the size of the selected instrument specifications), the design of the measured medium pressure (mainly used for the selected nominal pressure level meter), the working pressure (pressure level) is mainly used for the selected instrument pressure sensors.

On the one hand, it is difficult to have the field verification of such instruments. In addition, if the intent of the purchase is ready to apply the this kind of instrument 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 can easily determine the table all qualified performance, it is too early. Therefore, in order to ensure the working process of the instrument in the future in its measuring result is reliable and accurate, it is necessary before the formal installation to be taken to have the detection capability and qualification of the department for a full flow within the scope of the system verification.

(3) improve the process though, this kind of instrument to process installation and use of 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 (such as compressor, separator, pressure regulating valve, reducer, and pipe, elbow, etc.), keep straight pipe before and after the instrument inside sleek straight, ensure to clean single-phase fluid measured medium, etc.

It is necessary to strengthen the management of this kind of flowmeter, which has many features of automatic disposal and micro-power consumption. For example, in order to ensure the accuracy, reliability of meter long (to avoid unexpected shutdown and loss of data), should be periodically calibration system (every 1 "> ~ 2 years), transcribing header data (daily or weekly), replacement medium parameter (monthly or quarterly) and not regularly check the battery status, check the instrument coefficient and seal, etc.

Pay attention to internal maintenance if the flowmeter is required to check or clean the measuring chamber and its components of the instrument due to temperament or other reasons.
