Manufacturers of pressure bubble water level gauges have a large shipment volume of reservoir water level information technology

Description :

　　1、 Product Overview

　　Bubble type water level gauge is a high-precision intelligent device for water level measurement, which belongs to an indirect measurement device based on pressure sensors and air ducts. This product is in line with China's national water quality conditions and is mainly used for measuring water levels in small and medium-sized reservoirs, rivers and lakes, and drainage pipelines. It is also suitable for monitoring water levels and liquid levels in chemical, coal mining, sewage treatment, and water treatment plants. It is suitable for areas where well logging is inconvenient or expensive, and is easy to install and operate. It can detect various parameters such as water level and voltage, and can well meet users' needs for high precision and high stability of the product.

　　4、 Installation Guide:

　　1. Preliminary understanding of installation

　　The installation of the bubble water level gauge is actually the installation of the trachea. Whether the trachea is installed correctly will directly affect the measurement data of the instrument. Please strictly follow the operating steps for installation.

　　2. Three common installation simulation diagrams

　　3. Installation requirements for chassis:

　　① Bubble type water level gauge is a precision measuring instrument that needs to be installed in a safe location such as a cabinet with external protection or indoors (station building).

　　② The chassis of the bubble water level gauge must be wall mounted. Pay attention to installing the external air duct of the chassis with the head facing downwards.

　　4. Selection of installation points for civil engineering:

　　① The installation point of the water level gauge should be careful not to be installed below the water level to avoid the danger of being submerged by the water level gauge equipment after rising;

　　② Due to the need for wireless communication, it is important to pay attention to any special issues that may affect communication, such as high-voltage power lines or mountains, around the installation site;

　　③ For the selection of installation points for underwater gas chambers, it is not advisable to choose return water bays, areas with particularly fast water flow, or areas with a high amount of underwater garbage, in order to avoid the problem of blockage of underwater gas chambers;

　　④ The underwater air tank/chamber must be installed at a 45 ° inclination in the direction of the water flow or vertically downwards, and the installation position should be about 0.5m below the historical water level;

　　5. Installation requirements for trachea:

　　① When installing the bubble water level gauge air tube probe, the installation position and existence method are particularly important, which is related to the accuracy of water level measurement. The installation position of the probe must be such that it cannot vibrate with water flow and surges, and must be completely fixed.

　　② The air duct requires a protective pipe made of Φ 50mm galvanized stainless steel pipe for protection, which should be buried underground as much as possible to avoid human damage. The air line must follow a downward slope, and the curvature of all bends in the protective pipe should not be too sharp. The air duct should have a smooth passage, and high-density concrete blocks with a certain amount and stability should be inserted into key parts of the riverbank to fix the air duct, prevent flood threats or collapse, or fix the air duct on existing stable buildings.

　　③ The outlet of the trachea must generally be installed 0.5 meters below the water level. If there is a water purification device with a capacity of 2000 cubic centimeters, it can improve the reading accuracy of the pressure sensor.

　　④ The installation of the trachea on the riverbank can be divided into two types: one is slope installation, and the other is vertical installation.

　　⑤ Process diagram for connecting trachea and bubble water level gauge.

　　Note: Connect in the order shown in the picture, pay attention to inserting the trachea into the lower end of the quick connector thread and tightening the connector with a 6-inch adjustable wrench

　　6. Precautions for laying and installing trachea on site

　　Note 1: The trachea should be protected during transportation to prevent it from being cut by external forces or artificially damaged.

　　Note 2: For stations far from the riverbank (as shown in Figures 2 and 3), if the trachea is too long, it should be laid with steel pipes or buried with cement along the way. However, during the laying and burial process, do not harm the trachea to prevent scratches or cuts that may cause it to leak (check holes should be installed along the way to facilitate future maintenance of the trachea).

　　Note 3: In complex geographical locations, the protective tube can be directly fixed along the way (as shown in the figure below)
