Product Description
Air Chamber of Bubble Water Level Sensor
(HC.WQX-ACC)
Bubble water level sensor is high precision, high reliability, high intelligence,free cylinders, free logging, maintenance-free, anti-vibration, long life.
It is especially suitable for those places such as the open channels, lakes, large, middle, small rivers, reservoirs,or water pollution and corrosive industrial wastewater which it is not easy to build well logging or to build logging expensive .
The model HC.WQX40-1R is suitable for application with special request on volume, power,cost,embedded applications are also available.
Product Feature
1. Non-contact measurement, high stability, high accuracy (0.05%), high resolution;
2. Low power consumption,ultra-small size, easy to embedded applications, good stability, easy maintenance;
3. Easy to install, no need to build logging;
4. Seamlessly connect to the database and other equipment, standard RS485 (Modbus) / RS232 (Modbus) / 4-20mA;
5. Wide voltage design, with reverse polarity protection, overvoltage and overcurrent protection lightning surge absorption capacity;
The Measuring theory
Through the air filter of the bubble water level indicator ,air is filtered and purified. Then air pump press the air into air tank through the one-way valve. The air in the tank is separated into two routes to the pressure sensors of pressure control unit and air pipe to underwater. When the air pump stops blowing, the one-way valve is closed to form a sealed cavity connecting pressure sensor and underwater air pipe. According to the pressure transmitting principle,when the air in the air pipe reach a dynamic equilibrium, the pressure of the underwater air pipe duct will transmit to the pressure sensor of pressure control unit. So the pressure of the underwater air pipe duct is is equal to the pressure of the control pressure sensor unit. Subtracting the atmospheric pressure value with the pressure value,the water head pressure data can be obtained, thereby we can get the measured value by bubble water level indicator.
Application
♦ Rivers, lakes, tidal, reservoirs, groundwater and other natural bubble water level indicator detection. ♦ Urban flooding or waterlogging flood monitoring, such as low-lying land, drain monitoring. ♦ Secondary water treatment operations, such as urban water supply, sewage monitoring.
