As a new flowmeter product, the Verabar flowmeter is a new constant velocity flow probe that performs high-precision flow measurement of gases, liquids and vapors of different diameters by the differential pressure generated by the sensor in the fluid. Its outstanding advantage is that it can output a very stable, non-pulsating differential pressure signal, accurately reflecting the true flow velocity of the fluid, and is favored by users in the industrial control fields such as petroleum, chemical, metallurgy, light industry and water treatment.
Powerbar flowmeter installation technology:
The power meter flowmeter is a kind of precision measuring instrument. The installation requirements are relatively high. If the installation error or error will directly affect the measurement result, the installation regulations must strictly abide by the regulations, and the installation environment must be considered comprehensively. Conditions and process conditions ensure the quality of the installation and ensure the normal operation of the instrument. Each Verabar flowmeter is processed separately according to the process conditions used in the process system. Its specification and model are determined. It must be installed to the design process point during installation and cannot be installed at will. It has high requirements on the process environment and the use environment. Before installation, check the power bar and the installation environment to ensure that the installation position is reasonable and the use conditions are superior, so as to ensure the reliability of the flowmeter and the accuracy of measurement.
Verabar flowmeter inspection before installation:
The purpose of checking Verabar before installation is:
First, to ensure the integrity of the instrument and complete information.
1. Mainly check the technical agreement and packing list to confirm the integrity of the equipment and accessories. 2. Check the specification model and station number on the nameplate to confirm that the specification model and the number are consistent with the design, because each powerba They are all produced according to specific process conditions and are irreplaceable and replaceable. Therefore, it is necessary to strictly confirm the specification model and station number;
3. Check the sensor surface for damage, and the damaged sensor will bring errors to the measurement;
4, check the attachment for damage, the damage on the attachment will affect the installation quality, also bring errors to the measurement;
5, check the instructions, calculation books and other information is complete, because the differential pressure of the differential pressure transmitter must be determined according to the calculation book, and also according to the calculation book to check the working conditions, process conditions, calculation book It is essential.
Second, the purpose of the installation environment inspection is to ensure that the installation location is reasonable and the conditions of use are superior. According to the design conditions, check whether the operation and installation environment are within the requirements of Verabar, such as pressure, temperature, vibration, etc., according to the specific requirements of Verabar.
Third, after checking the instrument and installation environment, it is necessary to determine the specific way of installation of the instrument, not only to consider the model of the instrument, the specific medium (measured medium) of each power meter, but also the process conditions of the pipeline.
The model number of the instrument determines the installation method. The model has "-H-" for horizontal pipes and "-V-" for vertical and inclined pipes.
The type of medium to be measured determines the direction in which the power bar is installed on the horizontal pipe. When measuring the steam flow, it must be installed within 160° below the pipe.
The installation conditions must also consider the process conditions of the installation location, such as the position of the pipe bends and fittings before and after, the influence of different pipe fittings is different, and the installation requirements are also different. The specific requirements are shown in Table 1.
