1. Which type of liquid flowmeter is good?
2. Correct installation of three induction water flow meters.
The core of the correct installation of three induction water flow meters is to ensure independent measurement, avoid mutual interference, and ensure installation specifications.. 1. Before installation, prepare to confirm the installation position: choose a straight pipe section with stable water flow, no bubbles or impurities accumulation. The length of the upstream straight pipe section should be 10-15 times the pipe diameter, and about 5 times the downstream. Check the pipeline: Ensure that the noisy skin wall inside the pipeline is clean, without protrusions or depressions, and that the diameter of the pipeline matches the diameter of the flow meter. Installation process: The installation position planning: A certain distance should be maintained between the three flow meters to avoid mutual interference, and the lift difference is generally not less than 1 time the diameter of the pipeline. Cut the pipeline: Use professional tools to cut the pipeline in Xiangpeng, ensuring that the incision is smooth and free of burrs. Install sealing gasket: Install a suitable sealing gasket (such as rubber or fluororubber) at the cut to prevent water leakage. Connecting flow meters: using flange connection or threaded connection method. Flange connection: Align the flanges, thread the bolts and tighten them evenly to ensure good sealing. Threaded connection: Wrap the raw material tape around the thread, screw it into the pipeline interface, and tighten it moderately with a wrench. Wiring: Connect the signal cable correctly to the corresponding wiring terminal according to the instructions, paying attention to firm wiring and correct polarity. Fixed and supported: Use pipe clamps or brackets to fix the flowmeter to prevent displacement or damage caused by pipeline vibration or external forces. Debugging and inspection: Connect the power supply, check if the flowmeter display and reading are normal, observe if there is any water leakage at the connection, and promptly deal with any problems. 3. Precautions: The specific installation requirements of each flowmeter may vary depending on the brand, model, and applicable scenario. Before installation, it is necessary to read the product manual carefully. If necessary, consult the manufacturers technical support personnel to ensure correct installation.
3. What flowmeter is better for detecting groundwater
Electromagnetic flowmeter is the first choice for groundwater flow detection. According to specific working conditions, ultrasonic open channel flowmeter and clamp type ultrasonic flowmeter can be selected. Vortex flowmeter is only suitable for extremely clean groundwater scenarios
1. Electromagnetic flowmeter: The most preferred type 1 Adaptation advantages: It is not affected by the density, viscosity, and temperature of groundwater, and can stably detect groundwater containing sediment and suspended solids. It will not cause accuracy degradation or blockage problems due to medium impurities, and is the standard measuring equipment for most pressurized pipeline groundwater intake scenarios in China.
2. Selection subdivision:
(1) Integrated electromagnetic flowmeter: suitable for newly built pipeline intake ports for conventional excavation and installation, with stable measurement accuracy and easy daily maintenance;
;(2) Plug i
