1. The correct installation method of three induction water flow meters
The core of the correct installation method 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.

2. Is the air conditioning flow meter installed for water supply or return? It is usually installed on the main return water pipeline of the host. Due to the fact that the scale pin of the water flow meter is only used to measure the circulating water flow rate, from a functional perspective, installing it on the main engine outlet pipe and the main return pipe has the same effect. Specifically for the project itself, the most suitable installation location needs to be determined based on the specific purpose of measuring the circulating water flow rate. 3. How to debug and use an intelligent water flowmeter after installation
The debugging and use of an intelligent water flowmeter after installation must strictly follow the standardized process of power on initialization, parameter verification, zero point calibration, flow calibration, and signal verification. The core is to ensure measurement accuracy and operational safety, and it is strictly prohibited to plug or unplug wiring terminals with power on throughout the operation.
