Optimisation of measurement conditions! Liquid turbine flowmeter installation

Project Overview

　　Liquid turbine flowmeter is a commonly used flow measurement instrument, which is widely used in chemical, food, pharmaceutical, water treatment and other fields. In order to ensure its measurement accuracy and long-term stability, the correct installation and use of methods is essential. In this paper, we will introduce a variety of liquid turbine flowmeter installation methods to help users optimise the measurement conditions in practical applications, improve the measurement accuracy and stability of the flowmeter.

　　First, straight pipe installation

　　Straight pipe installation is the most basic installation of liquid turbine flowmeter, is also one of the most widely used. The installation requires the installation of a straight pipe in the fluid pipeline, so that the turbine flowmeter can measure the average flow rate of the fluid. The length of the straight pipe needs to meet certain requirements, it is generally recommended that the fluid inlet to install 10 times the diameter of the straight length of the pipe, the outlet to install 5 times the diameter of the straight length of the pipe, which can make the fluid flow line fully developed, to avoid fluid rotation and fluctuations on the impact of the measurement results.

　　Second, the ring pipe type installation

　　Annular piping type installation is suitable for liquid flow measurement in annular piping system, such as water circulation system. The installation requires the installation of a ring-shaped turbine flowmeter in the ring-shaped pipeline, and through the pipeline interface with the ring-shaped pipeline connection. In order to avoid the turbine flowmeter's effect on the resistance of the fluid, it is recommended to install the turbine flowmeter on the side wall of the annular pipeline so that it can measure the average flow rate.

　　Third, insertion type installation

　　Insertion type installation is suitable for the existing fluid pipeline occasions, can be punched through the fluid pipeline and inserted into the turbine flowmeter to achieve the flow measurement. This installation is relatively low on the pipeline requirements, but need to choose the appropriate turbine flowmeter according to the nature of the fluid and flow rate, and to ensure that its installation position is correct, to avoid affecting the fluid flow state.

　　Fourth, clamped pipe installation

　　Clamp installation is a more flexible installation, can be achieved by clamping the turbine flowmeter on the pipeline flow measurement. The installation does not require the pipeline perforation or transformation, and does not require the dismantling of the pipeline, so the impact on the pipeline is smaller, but you need to ensure that the clamping force is evenly distributed to avoid damage to the turbine flowmeter.

　　In practical application, users need to choose the appropriate installation method according to the actual situation, and strictly in accordance with the installation requirements of the turbine flowmeter for installation and use, in order to ensure the measurement accuracy and long-term stability. At the same time, it is also necessary to regularly check and maintain the turbine flowmeter, clean the pipeline and turbine in a timely manner, to avoid clogging of the pipeline and turbine wear and tear resulting in inaccurate measurement.
