A magnetostrictive water gauge for open channel water level measurement

Abstract

The invention relates to the field of water level measurement, in particular to a magnetostrictive water gauge used for open channel water level measurement. The magnetostrictive water gauge for measuring the water level of an open channel includes: an electronic warehouse, and a first measuring rod is fixedly installed at the bottom of the electronic warehouse. When the magnetostrictive water gauge for open channel water level measurement provided by the present invention is used, the controller controls the sliding device to realize the expansion and contraction of the second measuring rod and the first measuring rod, so as to be suitable for the needs of open channels of different depths, and at the same time The winding or pay-off operation of the waveguide wire is realized by the wire take-up mechanism, and then the device is installed in an installable position to realize the fixation of the device, which is used to improve the detection and installation requirements of the device with different depths of water channels, and improve the performance of the device. Adaptability: The waterproof performance between the first measuring rod and the second measuring rod is realized by sealing between the first measuring rod and the second measuring rod by the water lubricating bearing installed on the second measuring rod.

Description

technical field [0001] The invention relates to the field of water level measurement, in particular to a magnetostrictive water gauge used for open channel water level measurement. Background technique [0002] When measuring the water level of an open channel, a magnetostrictive water gauge needs to be used. The magnetostrictive water gauge can be used for water level measurement in the fields of agricultural irrigation channels, small river water levels, section water levels, urban flood control, and open channel flow. [0003] The existing magnetostrictive water gauge consists of four parts: a sensor probe, a signal processing unit, a liquid level float, and a limit snap ring. The top of the sensor probe is installed with an electronic compartment for controlling and monitoring the device. The sensor In the existing device, the probe is basically a whole measuring rod, which contains various components for detecting the water level, which can detect the water level of a c...

[0003] The existing magnetostrictive water gauge consists of four parts: sensor probe, signal processing unit, liquid level float, limit snap ring, wherein the top of the sensor probe is equipped with an electronic warehouse for controlling and monitoring the device, and the sensor In the existing devices, the probe is basically a whole measuring rod, which contains various components for detecting the water level, and can detect the water level at a certain depth, but for some small open channels or deep open channels It is said that it is impossible to measure the overall depth of the open channel, either the water gauge is too long, or the water gauge is too short, so the water gauge can only be installed at a fixed position on another side, which cannot meet different scenarios needs
