1. Is the flowmeter installed at the water pump outlet? Generally, it is recommended to install the flowmeter at the water pump outlet, but the installation position needs to be adjusted according to the pipeline layout and medium characteristics. 1. The core influencing factor for the selection of installation location is pipeline vibration environment (such as near the water pump). Anti vibration vortex street or electromagnetic flowmeter should be prioritized, while ensuring that the front straight pipe section is ≥ 5 times the pipe diameter. When measuring media containing bubbles, it is recommended to install it 2-3 meters above the outlet to avoid gas accumulation affecting the reading. 2. Installation requirements for special media treatment: When dealing with water flows containing sediment, a filter with ≥ 50 mesh should be installed at the inlet of the flowmeter, and a settling tank should be installed at the outlet of the water pump. In highly corrosive liquid scenarios, the installation location should avoid flange welding, and priority should be given to fully lined electromagnetic slow-moving dismantling flow meters. 3. Engineering maintenance precautions: Reserve maintenance space of ≥ 1.5 times the pipe diameter, and set up maintenance valve groups at flange connections. When installing in a ground well, it is required that the top of the equipment be at least 30cm lower than the well cover, and a moisture-proof junction box should be provided.

4. Scenario based installation plan example: In agricultural irrigation systems, it is recommended to install an additional pressure buffer tank at the outlet of the water pump; In the central air conditioning circulating water system, the installation po

sition of the flow meter should be kept at a distance of ≥ 8 times the diameter of the variable frequency water pump. In medical pure water systems, it is strictly required to install ultraviolet disinfection modules at the outlet after installation.

2. The ultrasonic flowmeter measures the water in the pipe, and the normal circulation reading is displayed. When the valve is opened to discharge water, the reading is __ hundred According to your problem description, if the normal circulation reading is displayed, it means that the slag backup section of the circulating water pump is in the open state, indicating that there is no problem with the instrument measurement and that the instrument is not installed upside down. The normal cycle reading is displayed normally. If it is a normal cycle button display, you can focus on the instantaneous flow value. If it is 0 and there is water in the pipeline, the sensor is installed upside down. As soon as the valve is opened to release water, the reading becomes negative. It is possible that the valve is too close to the sensor position of the instrument. Due to pressure, adverse flow conditions such as vortices and water hammer may occur after the valve is opened, causing distortion in the instrument measurement. If this is the case, the sensor needs to be shifted. If the valve is an electric variable frequency device with high power consumption, your power line and sensor signal line may be too close or share the same cable tray, causing interference with the rolling chain and distortion of the instrument measurement. Professional rectification is needed.
