1. functional features
This series of instruments are designed and manufactureπd according to the national standard GB/T11828.1-2002. The instrument l'evel rate, surge serious environment, with good accuracy and stabili§ty, especially suitable for hydrological station, ShuiKu Railway♦ Station, station dam, hydropower station, remote station use.
This series of equipment by the absolute value of encoding type water level sensor, di₩splay, sensor bracket, float, suspension, balance weight, RS485 communication interface and othφer components, is independent of the water level observation and measurement instrume✘nt, and can display, gate opening device, gate hoist control system is connected, composed∞ of computer integrated display and control the system (such as locks, hydropower, pumped stor×age power station, agricultural irrigation system, water supply and drainage syst★em); water level configuration of RS485 communication interface device, can↔ directly communicate with the computer network machine, composed of hydrol★ogical automatic monitoring system, hydrological satellite telemetry system; configur₹ation storage recording unit can be widely used in hydrologica♦l station.
This series of instruments is suitable for use in fine wells ≥and general logging with a diameter of 20 cm to 30 centimeters.
