Yongzhou Airport Fire Water Pool Level Solution

System Requirements Analysis
According to the trial version 4.2.2, Article 4, and 4.2.3, Article 9 of the "Regulations for the Quality Inspection and Evaluation of Fire Protection Facility Installation in China (DB37/242-2008)", the water level of the fire water pool and the fire water tank should be displayed in the fire control room. Based on fire regulations, ensuring the full water level of the fire water pool and the high-level fire water tank, and their remote monitoring in the fire control room, is extremely important. If the fire control room does not have a liquid level display instrument for the fire water pool and the high-level fire water tank, there is a high risk of failing the acceptance inspection of the building fire protection facility installation according to the fire regulations. Therefore, it is necessary to monitor the real-time liquid level of the fire water pool and tank in the fire control room, which requires the use of the WH311 fire water tank liquid level display.

System Overview
The WH311 liquid level sensor probe is directly immersed in the bottom of the user's fire water pool/tank. The WH6 fire-specific liquid level display is installed in the fire control room, connected by a 2*1.5 square shielded cable. It displays the real-time fire water level and has a high/low level alarm system to ensure the fire water level remains high.

Application Challenges:
1. Electromagnetic interference exists in the monitoring scene.
2. The product is required to operate stably and accurately.

Solution Advantages:
  1. Provides a variety of product solutions to meet different operating conditions.
  2. Customizable products to meet complex operating conditions.
  3. Excellent product quality, high precision, high stability, and high protection level.

Project Description

Customer Needs

Yongzhou Airport has two fire water pools. It requires unified display in the fire center, with a light column showing the percentage, and high/low level alarm signals directly connected to the fire host.

Solution

Wanhe technology engineers provided product selection according to the specific needs of the airport. After factory debugging according to user requirements, the products were shipped to the Yongzhou Airport construction team and then to the airport.
The WH311 lightning protection level sensor is directly placed at the bottom of the fire water pool. The WH6-T light column type level display is installed in the dedicated fire control cabinet, displaying the fire water pool level in real-time. The light column simulates the percentage of the water pool in real-time, providing a more intuitive understanding of water level changes. The installation and wiring were successfully completed via video conferencing with the airport's construction team technicians.
