Agricultural ultrasonic liquid level meter

Abstract

The invention relates to the technical field of liquid level meters, and discloses an agricultural ultrasonic liquid level meter which comprises a mounting plate and a liquid level meter body fixedlyarranged at the upper end of the mounting plate, a fixed plate and a movable plate are sequentially arranged at the lower end of the mounting plate from top to bottom, the upper end of the fixed plateis fixedly connected with the bottom of the mounting plate, and a through groove is formed in the right end of the movable plate. A rotating plate is rotatably connected into the through groove through a rotating shaft, a circumferential wall matched with the rotating shaft is formed in the lower end of the rotating plate, the upper end of the rotating plate extends out of the through groove andis fixedly connected with the lower end of the fixed plate, a blind hole is formed in the bottom of the through groove, and a first strip-shaped hole is formed in the lower side hole wall of the blindhole; and a locking mechanism is arranged in the blind hole. The installation position can be conveniently adjusted according to different containers, equipment universality is good, operation is easy, and the glass surface of the probe can be prevented from being dewed.

Description

technical field [0001] The invention relates to the technical field of liquid level gauges, in particular to an agricultural ultrasonic liquid level gauge. Background technique [0002] In the measurement, the ultrasonic pulse is sent by the sensor (transducer), and the sound wave is reflected by the liquid surface and is received by the same sensor or ultrasonic receiver, which is converted into an electrical signal through a piezoelectric crystal or a magnetostrictive device, and is transmitted and received by the sound wave time to calculate the distance from the sensor to the surface of the liquid to be measured. Due to the use of non-contact measurement, the measured medium is almost unlimited, and can be widely used to measure the height of various liquids and solid materials. [0003] When the existing agricultural ultrasonic liquid level gauge is used, it is sometimes installed on the top of the container according to needs, and sometimes it is installed on the side...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems in the prior art that it is not convenient to adjust the installation position according to different containers, the equipment has poor versatility, and the operation is cumbersome, and a kind of agricultural ultrasonic liquid level gauge is proposed.
