WYQ-80 type bubble level gauge Introduction: The WYQ-80 bubble level gauge is suitable for environments requiring continuous and precise measurement of water levels. As it does not require the construction of a water level well, the bubble level gauge is one of the most ideal water level monitoring instruments for monitoring water levels at hydrological stations, reservoirs, hydropower pressure regulating wells, dam piezometers, and upstream and downstream water levels. It features convenient installation and maintenance, flexible operation, stable and reliable operation, and high accuracy. The internal air pump of the bubble level gauge generates compressed air, which flows through a dedicated airflow line and enters the air chamber at set intervals. In the air chamber, bubbles emerge evenly and enter the water. The relationship between the water level (h) above the bubble chamber hole and the hydrostatic pressure (P) inside the measuring tube is established as follows: P = ρgh Assuming the density of the liquid remains constant, there exists a certain linear relationship between the measured liquid level and the air pressure within the measuring tube. By measuring the air pressure inside the measuring tube, the current water level can be calculated. This is the basic principle behind the measurement of liquid level using a bubble level gauge. Features: 1. Ultra-low power consumption, with a quiescent current of ≤15mA 2. Wide voltage range: 10VDC~14VDC, normal operating voltage: 12VDC 3. Wide range: 0~10m, 0~20m, 0~40m, 0~80m are optional 4. Multiple communication modes: Digital: 485 (MODBUS), Analog: 4~20mA 5. Multiple working modes: scheduled collection and quantitative collection (which can achieve ultra-low power consumption, intelligently determine and adjust the air pump's working intervals and time, ensuring real-time data while minimizing power consumption to the greatest extent possible) 6. Supports real-time data collection. Equipped with buttons: short press for real-time data collection, long press for sensor calibration 7. Embedded clock module 8. Working status indication 9.2M bytes of solid-state storage, capable of circularly recording 170,000 pieces of data (with time tags) 10.
