- AOBWL bubble water level gauge
◆Measurement principleThe bubble water level gauge is an instrument used for measuring water levels. It mainly consists of components such as an air source, air tube, and pressure sensor. During operation, the air source inflates the air tube, causing bubbles to form at the tube's submerged end. When the water level changes, the pressure exerted on the bubbles also varies accordingly. The pressure sensor calculates the water level height by detecting these pressure changes. The bubble water level gauge offers advantages such as a simple broussonetia papyrifera structure, easy installation, and relatively high accuracy, enabling real-time and accurate monitoring of water level variations.
◆Main Features
▶Measurement parameters: (Elevation) Water level;▶Color LCD display with backlight, full Chinese operation menu;▶12 common elevation display modes;▶Non-contact measurement with high accuracy, goodstability, and easy maintenance;▶Built-in air pump, no need for external gas cylindersor other air sources;▶Built-in air purification device at the air inlet;▶Automatic atmospheric balance and self-zero calibration;▶Aluminum alloy casing;▶Output signals: Standard current, RS485, optional wireless 4G communication;▶Automatic data collection and analysis, with self-diagnosis and early warning for faults;▶No dedicated logging configuration required;▶IP67 protection rating;▶Awarded: Multiple patents and software copyrights;◆Application Scenarios
The product can accurately perform water level monitoring tasks in natural water bodies suchas small, medium, and large rivers, reservoirs, as well as upstream and downstream of dams, oceans, or locations like petroleum, chemical plants, sewage treatment plants, and urban drainage pumping stations. It is particularly suitable for flowing water bodies and scenarios where water pollution is severe, corrosion is strong, or constructingmonitoring wells is inconvenient or costly, suchas industrial wastewater monitoring and groundwater level monitoring.11—— -
