Currently, the WH311 deep well probe uses a laser static pressure principle (laser calibration zero point full scale), greatly simplifying the measurement process and reducing the cost of on-site data acquisition. The WH311 is easy to install; simply fix the level probe 3-5 meters above the deep well pump when lowering the pump into the well. Suitable for deep well water level measurement and monitoring, solving the problem of difficult deep well water level measurement.
The Hongshan 6979 Commercial Center has four fire water pools, distributed around the underground parking lot, with a water depth of 6 meters and a distance of approximately 3000-4000 meters from the fire control room. The user now requires, according to the requirements of the fire construction specifications “GB 50974-2014 4.3.9 clause” (see Figure 1): Fire water pools should be equipped with on-site water level display devices, and devices should be installed in the fire control center or duty room to display the water level of the fire water pools; at the same time, there should be maximum and minimum alarm water levels.
The Shenzhen Metro complex has two fire water tanks, each 5 meters high. The requirement is to display the water level in real-time in the fire control room, simulating the water level display and adding high and low level alarms. Project Highlights: 1. Two underground fire water tanks, each 5 meters high; 2. The fire water tank level signal needs to be transmitted 300 meters to the fire control room for display. The communication signal adopts an anti-interference design for long-distance transmission; 3. Not only real-time level display is required, but also intuitive percentage light column representation of the fire water tank water level, and high and low level alarms are required.
