Annubar flowmeter installation process
2011-5-23 16:53:12

(均速管流量计)测量范围广泛,适用于大部分现场介质的测量。 Annubar flowmeter (average speed tube flowmeter) has a wide measurement range and is suitable for the measurement of most on-site media. Is a recognized energy-saving flow meter. 现场安装正常采用的是直接插入式(也就是焊接式)的连接方式。 Today, I will give you a detailed summary of the common installation method of Annubar flowmeters. For production enterprises, we all know that the direct installation (that is, welding) connection method of Annubar flowmeters is normally used for field installation.
1. The first premise of installation is to confirm whether the on-site straight pipe section meets the requirements. For specific requirements, refer to the relevant manual or consult the technical department of the company, and then determine the installation direction of the flow meter according to the direction of the on-site fluid.
2. After the direction is determined, make a hole in the pipe with the help of a hole opener (the conventional hole size is 25mm)
a, single-sided support; that is, a hole is opened in the pipeline according to the size of the Annubar sensor. This installation method is suitable for pipelines with a diameter of less than 600mm on the site, because in a small-aperture installation method, this installation method is sufficient The stability of the sensor itself ensures measurement accuracy.
b; double-sided support; after determining the installation direction, open two holes of the same size in the symmetrical position on the pipe, which is opposite to the single-sided support above, that is, for the measurement of large diameter, in order to ensure the stability of the sensor To install Annubar flowmeter, use double-sided fixing.
插入管道中,用点焊的方式将传感器固定在正确的位置上,但是要求探头部分在整个管道内径且与中心线在同一条中心线上 3. Insert Annubar flowmeter into the pipe, and fix the sensor in the correct position by spot welding, but the probe part is required to be in the entire pipe inner diameter and on the same centerline with the centerline.
4. Finally, the entire welding joint is completely welded, and the welding part is rust-proofed.
和钢板还是采取上述安装方式。 For the on-site cement pipeline, for the convenience of on-site installation, the company will also provide a steel plate with the Annubar flowmeter at the same time. The steel plate and the on-site pipeline are bolted to each other. If you have any specific questions, you can contact Jiangsu Dongxiang Instrument Technology Department at Tel: 0517-86900920
