Wan Guo Data: Multiple air conditioning water cooling system level control solutions

System Requirements Analysis
The water-cooled circulating water pool requires a liquid level monitoring device to monitor the liquid level data in real time and ensure normal operation. Air conditioning water cooling is related to the normal operation of the server, which requires high precision and high stability of the product. A lightning protection module is an important requirement for harsh weather conditions to ensure the long-term stable operation of the product.

System Overview
The WH311 liquid level sensor probe is directly placed at the bottom of the user's water-cooled water pool tank. The WH6 dedicated liquid level display is installed in the control room, connected by a 2*1.5 square shielded cable, and displays the actual water level of the pool in real time. It also has a high and low liquid level alarm system to ensure that the water level always operates at a high level.

Application Challenges:
1、High equipment maintenance costs;
2、Requires stable performance and low-power products.

Solution Advantages:
1、Timely solve problems such as insufficient pipeline pressure, insufficient circulating water temperature, and insufficient hot water supply to ensure heating safety;
2、A variety of product choices, which can be selected according to the working conditions and actual needs.

I. Specific Requirements

User: GDS
GDS (NASDAQ: GDS; HKEX: 9698) is a leading operator and service provider of high-performance data centers in China.

GDS stores servers for many large Internet companies, such as Alibaba, SF Express, and Tencent. The servers require water cooling, and the user now has seven large water-cooled circulating water pools that require liquid level monitoring.
Requirement 1: Real-time display of the real-time liquid level of seven water-cooled water pools;
Requirement 2: Each pool must have a high and low liquid level alarm device;
Requirement 3: The liquid level signal needs to be transmitted to the control room to provide the liquid level signal to the DCS control system;

Special Requirements:
Because air-conditioning water cooling is related to the normal operation of the server, this requires high precision and high stability of the product. A lightning protection module is an important requirement for harsh weather conditions to ensure the long-term stable operation of the product.

II. Requirements Analysis

  1、 Measurement Object
7 water-cooled pools, pool depth 0.5 meters, real-time water level monitoring and remote transmission signal function required.
  2、Real-time display in the pump room, high and low liquid level alarm
Real-time display of water level in the pump room, with high and low liquid level alarm.
  3、Data remote transmission, compatible with Honeywell DCS system
The WH6-A1 display has a 4-20MA output module, which is transmitted to the control room for the DCS control system.

III. Equipment Composition

The water level liquid level display system mainly includes:
1、Water level data acquisition and transmission equipment: WH311 lightning protection type liquid level probe;

2、Data display equipment:
WH6-A1 liquid level, with 4-20MA output module for Honeywell's DCS control system.
