The correct selection of customized alcohol turbine flow meter china can ensure the better use of alcohol turbine flowmeter. What kind of alcohol turbine flow meter should be selected according to the physical and chemical properties of the measured fluid medium? Make the diameter, flow range, lining material, electrode material and output current of customized alcohol turbine flowmeter china? Can adapt to the properties of the measured fluid and the requirements of flow measurement.
1. Precision function inspection of customized alcohol turbine flow meter china
Accuracy grade and function: select the accuracy grade of the instrument according to the measurement requirements and application occasions, so as to achieve economic efficiency. For example, for the occasions of trade settlement, product handover and energy measurement, the accuracy level should be higher, such as level 1.0, level 0.5 or higher; For the occasion of process control, different accuracy levels shall be selected according to the control requirements; In some cases where only the process flow is detected without accurate control and measurement, you can choose a slightly lower accuracy level, such as level 1.5, level 2.5, or even level 4.0. At this time, you can choose the low-cost plug-in ethanol flowmeter.
2. Medium measured by customized alcohol turbine flow meter china
When measuring the medium flow rate, instrument range and diameter, and measuring the medium in general, the full-scale flow of the ethanol flowmeter can be selected in the range of 0.5-12m / s. The specification (caliber) of the selected instrument is not necessarily the same as that of the process pipeline. It should be determined according to whether the measured flow range is within the flow rate range. That is, when the flow rate of the pipeline is low and cannot meet the requirements of the flow instrument, or the measurement accuracy under this flow rate cannot be guaranteed, it is necessary to reduce the diameter of the instrument, so as to improve the flow rate in the pipe and obtain satisfactory measurement results.
Installation of customized alcohol turbine flow meter china
In order to ensure the correct installation position and installation method of the turbine, it is necessary to select the correct alcohol measurement method
Requirements for straight pipe section of customized alcohol turbine flow meter china: the customized alcohol turbine flow meter must be installed horizontally on the pipeline (the inclination of the pipeline is within 5). During installation, the flowmeter axis shall be concentric with the pipeline axis and the flow direction shall be accurate. The upstream pipe length of customized alcohol turbine flow meter shall have an equal diameter straight pipe section of no less than 2D. If the installation site is allowed, it is recommended that the upstream straight pipe section is 20d and the downstream is 5D.
Requirements for piping of customized alcohol turbine flowmeter china: the inner diameter of upstream and downstream piping at the installation point of alcohol turbine flow meter is the same as that of flowmeter.
Requirements for bypass pipe of customized alcohol turbine flow meter china: in order to ensure that the maintenance of customized alcohol turbine flow meter will not affect the normal use of medium, cut-off valves (stop valves) shall be installed on the front and rear pipes of the flowmeter, and bypass pipes shall be set at the same time. The flow control valve shall be installed at the downstream of the flowmeter. When the customized alcohol turbine flow meter china is used, the stop valve installed at the upstream must be fully opened to avoid unstable flow of fluid in the upstream part.
