Absolute level meter

Abstract

The invention discloses an absolute level meter which comprises a controller, an encoder, an anti-sliding wheel, a leveling bracket, a heavy punch, a heating floater and a measuring rope, wherein the controller is arranged in a waterproof aluminum shell; the controller is connected with the encoder; the encoder is arranged on the leveling bracket; the anti-sliding wheel is fixed on a rotating shaft of the encoder; the measuring rope is hung in an anti-sliding slot in the anti-sliding wheel; the heavy punch and the heating floater are respectively connected with the two ends of the measuring rope.

Description

technical field [0001] The invention relates to the field of water level measurement, in particular to an absolute water level gauge. Background technique [0002] A water level gauge is an instrument that automatically measures and records the water levels of rivers, lakes, irrigation canals and other water bodies. According to the sensor principle, it can be divided into absolute type, tracking type, pressure type and reflective type, etc. Among them, the float water level gauge is widely used in the environment of large water level variation and severe surge due to its good measurement accuracy and working stability. Hydrological station, reservoir station, dam station, telemetry station, hydropower station. At present, most float water level gauges on the market use incremental encoders. Since incremental encoders do not have the power-off memory function, once the power is off, the staff needs to go to the site to re-calibrate the water level, which invisibly increases...

AI Technical Summary

Problems solved by technology

At present, most float water level gauges on the market use incremental encoders. Since incremental encoders do not have the power-off memory function, once the power is off, the staff needs to go to the site to re-calibrate the water level, which invisibly increases the workload of the site personnel.

In addition, the single data communication channel is also a common problem. Most water level gauges use a single channel to send data. Once the communication line fails, the remote control will make a wrong judgment because the water level data is not updated in time, resulting in huge economic losses. Even Cause production safety accidents and affect production and life safety in downstream areas

The use of traditional communication protocols for data interfaces is also a problem that cannot be ignored. The communication interfaces used by existing water level gauges are generally RS232, RS485, analog, audio and other traditional data interfaces. These interfaces belong to early products, with short transmission distance and high communication speed. Slow, the line needs to be laid repeatedly, and the network cannot be quickly established

To sum up, the current water level gauge products on the market can no longer meet the automatic measurement requirements in the new situation
