1. Explanation of LZB-80 Glass Rotary Flow Meter
Explanation of LZB-80 Glass Rotary Flow Meter LZB-80 Glass Rotary Flow Meter is a flow measurement instrument with high sensitivity, wide measurement range, low pressure loss, and easy use and maintenance. The following is a detailed explanation of the flowmeter:
1. Selection of flow range: The selection of flow range determines the diameter size of the flowmeter. When choosing, it is necessary to consider the flow rate and pressure of the medium, as well as the required measurement accuracy of He Xinfeng. A flow meter that is too large may not be suitable as its accuracy may be affected. Therefore, the appropriate diameter of the tank head should be selected according to the actual traffic demand. Object of measurement: The object of measurement includes the type of medium, pressure magnitude, chemical properties, etc. For corrosive media, corrosion-resistant flow meters should be selected to ensure measurement accuracy and instrument lifespan. Price factor: The price of a flowmeter is related to its accuracy. The higher the precision of the flowmeter, the higher the price. Therefore, when making a choice, a balance should be made between actual needs and economic conditions.
2. Technical parameter indication: The volumetric flow rate value indicated by the flowmeter.
. Model specifications: LZB/J series, LZB/J-F series. Diameter: DN4-100. Measurement range: Water (20 ℃): 1L/h~100m3/h. Gas (101325Pa, 20 ℃): 16L/h~3000m3/h. Range ratio: 10:1. Accuracy levels1.5, 2.5, 4, 6. Nominal pressure: DN4-10

3. Installation requirements: Pipeline cleaning: Newly installed pipelines should be flushed clean and tidy first to avoid impurities from affecting the flowmeter.
. Technical parameter inspection: Before use and installation, the technical parameters such as measurement range, accuracy level, rated working pressure, temperature, etc. should be checked to ensure that they meet the requirements for use. This is a crucial step in ensuring the proper functioning of the flow meter. Remove the top lining: Before installation, the top lining that serves as transportation protection in the flowmeter should be removed, and the cone tube should be checked for damage and whether the float can move freely up and down. Installation can only be carried out after confirming that everything is normal. Vertical installation: The flowmeter should be installed vertically on a vibration free pipeline, and the angle between the centerline of the rotor flowmeter and the plumb line should not exceed 5 degrees. For large-diameter flow meters, due to their weight, reinforcement and support measures may be necessary to avoid pipeline bending. Avoid external force injury: During installation, it is necessary to avoid excessive external force injury to the rotor flowmeter. The valve should be opened slowly to prevent damage to the flowmeter due to sudden pressure changes. (Note: The above image is an example of the LZB-80 glass rotor flowmeter, and the specific appearance may vary depending on the model and manufacturer.). ）In summary, LZB-80 glass rotor flowmeter is a high-performance and easy-to-use flow measurement instrument. Strict adherence to regulations is required in terms of selection, technical parameters, and installation
