Abstract

The utility model discloses an ultrasonic wave liquid level measurement device. A set of ultrasonic wave distance measurement module is arranged at the top end of a fluid container, wherein the set of ultrasonic wave distance measurement module is connected with a single chip microcomputer in a signal mode, wherein the single chip microcomputer is arranged outside the fluid container and is connected with a display module. The ultrasonic wave liquid level measurement device has the advantages that height of fluid in the container can be measured indirectly by means of ultrasonic waves, so that the aim of accurate measurement and the aim that no damages to a measurement instrument exist are achieved. The ultrasonic wave liquid level measurement device is small in size, simple in installation and capable of displaying a liquid level through a liquid crystal display circuit.

Description

A kind of ultrasonic wave liquid level measuring apparatus
Technical field
The utility model belongs to the detection technique field, relates to a kind of ultrasonic wave liquid level measuring apparatus.
Background technology
In the flow container that large oil tank, natural gas tank, salt industry use the measurement of liquid level normally used be directly to measure or mechanical type is measured, these measuring methods or at the chamber wall uplifting window, add mechanical surveying instrument, because what store in these flow containers all is special liquid, major part all is corrosive, so use above measuring method can cause the corrosion-damaged of tank body or surveying instrument itself, and outside leakage, the health of harm survey crew.
Summary of the invention
The purpose of this utility model provides a kind of ultrasonic wave liquid level measuring apparatus, has solved because direct the measurement causes surveying instrument can be subjected to corrosion-damaged problem.
The technical scheme that the utility model adopts is, a kind of ultrasonic wave liquid level measuring apparatus arranges a cover ultrasonic distance measuring module on the top of flow container, and ultrasonic distance measuring module is connected with the single-chip microcomputer signal that is arranged on the flow container outside, and single-chip microcomputer is connected with display module.
The beneficial effects of the utility model are, can detect and show the height of liquid level, by liquid crystal display circuit liquid level are shown simultaneously; Volume is little, installs simply, and indirectly measurement, so to not infringement of measurement mechanism itself.
Description of drawings
Fig. 1 is the structural representation of the utility model ultrasonic wave liquid level measuring apparatus embodiment.
Among the figure, 1. ultrasonic distance measuring module, 2. single-chip microcomputer, 3. display module.
Embodiment
With reference to Fig. 1, the structure of the utility model ultrasonic wave liquid level measuring apparatus is, on the top of flow container one cover ultrasonic distance measuring module 1 is set, ultrasonic distance measuring module 1 is connected with single-chip microcomputer 2 signals that are arranged on flow container outside (such as the PCO plant control office), and single-chip microcomputer 2 is connected with display module 3.
Comprise the ultrasonic transmission/reception integrated device in the ultrasonic distance measuring module 1.
Display module 3 comprises LCD or print out equipment.
The principle of work of the utility model device is, utilize Single-chip Controlling ultrasonic distance measuring module emission ultrasound wave, detection begins time of consuming when receiving ultrasound wave from the emission ultrasound wave, the speed of utilizing sound in air, to propagate, calculate ultrasonic sensor to the distance between the liquid level, at last with jar in can deposit liquid height to deduct liquid level be exactly the true altitude of pot liquid to the height of sensor.
Ultrasonic wave liquid level measuring apparatus of the present utility model uses ultrasonic sensor, utilizes the simple physics reason that the pot liquid height is measured indirectly, thereby reaches the not purpose of damage measurement instrument.
