WFX-40 photoelectric water level gauge

1. functional uses
This series of instruments are designed and manufactured according to the national standard GB/T11828.1-2002. The instrument has good measurement accuracy and stability under the condition of large water level variation and strong surge. It is especially suitable for hydrological station, ShuiKu Railway Station, gate dam station, telemetry station and Hydropower station.
This series of equipment by the absolute value of encoding type water level sensor, display, sensor bracket, float, suspension, balance weight, RS485 communication interface and other components, is independent of the water level observation and measurement instrument, 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 storage power station, agricultural irrigation system, water supply and drainage system); water level configuration of RS485 communication interface device, can directly communicate with the computer network machine, composed of hydrological automatic monitoring system, hydrological satellite telemetry system; configuration storage recording unit can be widely used in hydrological station. This series of instruments is suitable for use in fine wells and general logging with an inner diameter of 7 centimeters, 10 centimeters, 20 centimeters to 30 centimeters.
