1. FTU installation height standard
The FTU installation height needs to be adjusted according to the equipment type and scenario, and the conventional reference standard is concentrated in the range of 0.4-1.8 meters.
1. Equipment type and installation height are closely related. "FTU" as an equipment abbreviation needs to specify the specific type. Based on similar equipment experience, the installation height should meet the three principles of operational convenience, maintenance accessibility, and safety compliance. The following are common equipment categories for comparison:
2. Reference for installation height of similar equipment 1 Firefighting equipment: • Fire pump coupler (wall mounted/above ground): The center of the water inlet is 0.7 meters above the ground • Underground water pump coupler: The center of the water inlet is 0.4 meters above the ground • Fire flow meter: The conventional installation height is 1.5-1.8 meters, and adjustments to the pipeline diameter and site conditions need to be considered. 2 Hydraulic control equipment: • Foot valve: standard height of 10-20 centimeters, additional 5 centimeters required when including fittings
III. Typical adaptation scenarios. ⊙ Industrial scenarios: equipment is mostly installed at around 1.5 meters, taking into account instrument visibility and collision prevention requirements. ⊙ Underground pipeline network: underground equipment height is usually controlled at 0.4-0.7 meters to avoid siltation and affect functions. ⊙ Public facilities: equipment involving personnel operation is recommended to be 1.2-1.5 meters wide, which meets ergonomic requirements. When implementing, it is recommended to combine the technical paramet

2. Installation position of ultrasonic flowmeter in fire pump room
Ultrasonic flowmeter in fire pump room should be installed at the inlet and outlet pipelines.
. Specifically, the selection of installation location needs to follow the following rules:1. Installation of inlet pipeline: The ultrasonic flowmeter should be installed at the outlet of the water pump. This position ensures that the flow meter measures the water flow output by the pump, accurately reflecting the working status of the pump. 2. Installation of the outlet pipeline: In the outlet pipeline, the ultrasonic flow meter should be installed at the outlet. In this way, the flow meter can measure the water flow leaving the fire pump room, which helps monitor the flow situation of the entire system. During the installation process, it is also important to pay attention to the following points to ensure measurement accuracy: 1. Avoid turbulent flow areas: flow meters should be kept away from areas that are prone to turbulence, such as valves, bends, and pumps. The unstable water flow in these areas can affect the measurement accuracy of the flow meter. Therefore, it is recommended that the length of the upstream straight pipe section be no less than 10 times the pipe diameter, and the length of the downstream straight pipe section be no less than 5 times the pipe diameter (if the pipeline is cumbersome, it needs to be appropriately extended).
