Abstract
The application relates to liquid detection equipment and more specifically relates to a non-contact liquid level detection apparatus. The non-contact liquid level detection apparatus, composed of a compressed air pipe, an electromagnetic throttle valve, a pressure obtaining pipe, a capillary tube and a pressure sensor, is characterized in that an air outlet end of the compressed air pipe is connected with the electromagnetic throttle valve and the capillary tube, the other end of the electromagnetic throttle valve and the other end of the capillary tube are in connection with the pressure obtaining pipe, the bottom of the pressure obtaining pipe is disposed inside a liquid tank, and the top of the pressure obtaining pipe is equipped with the pressure sensor. The advantages of the application are that the non-contact liquid level detection apparatus is characterized by being easy to operate and convenient to use, stable in performance, high in detection precision and low in cost, widely applicable, etc.
Description
Technical field
This patent relates to liquid detecting equipment, is specially a kind of Non-contact type liquid level detecting device.
Background technology
The direct contact type liquid-level detecting methods such as existing throw-in type, because its sensor is placed under liquid, perishable, easily stifled, easily leak inefficacys, easy high temperature failure, be not suitable for applying under complex working conditions; The contactless liquid-level detecting method such as ultrasound wave is subject to the impact of the factors such as floaters on surface, foam and transducer dewfall, uses and is limited to.Be difficult to detect the liquid level under high concentration, high chroma, corrosivity, high temperature, severe toxicity, radioactivity, many complex working conditions such as inflammable, explosive.
Summary of the invention
This patent, for above technical matters, provides a kind of Non-contact type liquid level detecting device, and object is the level detection under applicable Various Complex working condition.
The concrete technical scheme of this patent is as follows:
A kind of Non-contact type liquid level detecting device, by compressed air hose, electromagnetic throttle valve, pressure pipe, kapillary, pressure transducer, formed, the outlet side of compressed air hose connects electromagnetic throttle valve, kapillary, electromagnetic throttle valve, the other end capillaceous connect pressure pipe, the bottom of pressure pipe is arranged in liquid tank, and pressure pipe top arranges pressure transducer.
The chemical property of take shows as inertia gas with respect to detected fluid medium is indirect contact medium.First gas pass through restriction device, and after throttling, gas is pressed under open-top receptacle liquid and is formed bubbling by pressure pipe with low flow velocity, and after throttling, gaseous tension is usingd pressure transducer detection as liquid level signal.Wherein pressure pipe, inert gas can be selected different materials and type according to the chemical property of detected fluid.
This equipment mainly utilizes the fluctuation of capillary-compensated isolation compressed gas pressure and compressed gas pressure, what guarantee measuring cell (or pressure transducer) detection is the bubbling pressure that can truly reflect liquid level, do not need directly to contact with liquid, the liquid level being applicable under high concentration, high chroma, corrosivity, high temperature, severe toxicity, radioactivity, many complex working conditions such as inflammable, explosive detects.The features such as that this Level meter has is simple to operate, easy to use, stable performance, widely applicable, accuracy of detection high price is low.
Accompanying drawing explanation
Fig. 1 is patent structure schematic diagram.
Wherein, 1---compressed air hose, 2---electromagnetic throttle valve, 3---pressure pipe, 4---kapillary, 5---pressure transducer, 6---liquid tank.
Embodiment
Below in conjunction with embodiment, this patent is described further.
A kind of Non-contact type liquid level detecting device, by compressed air hose, electromagnetic throttle valve, pressure pipe, kapillary, pressure transducer, formed, the outlet side of compressed air hose connects electromagnetic throttle valve, kapillary, electromagnetic throttle valve, the other end capillaceous connect pressure pipe, the bottom of pressure pipe is arranged in liquid tank, and pressure pipe top arranges pressure transducer.
