Turbine flow meter bearings – small but important

A turbine flow meter is a commercial and widely popular type of flow meter that is dependent on the rotation of the turbine due to the inflow of a fluid into a transportation chamber. Hence, since it employs turbines for the measurement of the flow, it is only natural that the rotational parts of the turbine would be based around the turbine flow meter bearings. The choice of the proper bearings often determines the efficiency of the flow meter on a whole. The choice of the bearings are primarily based on the lubricity and the operating temperature of the fluid being considered for measurement.

The corrosion of the bearings are a huge factor to consider in case of the flow meter. This is because more often than not, the turbine flow meter is used in order to control the flow of hazardous materials like chemicals or crude oil. These fluids often have conditions which border on the extreme. In such cases, in order to ensure the smooth operation of the device, it is only natural to use bearings which will last. Relevant turbine flow meter bearings are not easy to choose. Several factors need to be taken into consideration before making thee choice to ensure the errors stay in the acceptable range.

Besides, the choice of bearings also determine the rolling friction which will be encountered. It is not a good point for the resistance to be more or less than the predicted value. Otherwise, it results in the readings to change unpredictably. Besides, the conservation of energy is also a pre requisite while making the choice. Since the turbine flow meter is a constant flow meter, that is, a flow meter which keeps on working indefinitely, the turbine flow meter bearings are the most important part of the whole assembly. Quite a few flow meters are now manufactured with ceramic bearings instead of metallic ones to ensure better values since they are more corrosion resistant.

At the end, a measurement is dependent on the fact that the values do not deviate too much from their pre-determined range. Otherwise, the corrections done in order to keep the flow meter accurate may result in its malfunction instead. Flow meters are renowned for their accuracy. However, unless the conditions under which they work be specified, this accuracy becomes totally meaningless. In this context, an accurate summary of the kind of use that it will be put to is just as much important as is the usage of the proper parts.
