Description
Technical field
The present invention relates to a kind of tongue tube sensor tank gage, particularly relate to a kind of tongue tube sensor tank gage.
Background technology
Nowadays the detection of the liquid position in the large-scale device for storing liquid such as storage tank, water tank, boiler water pot, groove, pond, storehouse is indispensable.The liquid real time position extracts, and brings great safety coefficient to people in safety in production and life.The device of survey liquid level commonly used, the device frequency of employing ultrasonic sensor is narrower and driving voltage is higher, and design is complicated; Utilize the device of liquid conductivity, when liquid does not have conductive characteristic or liquid to avoid contacting electricity, just lost effect; Utilize the also device of power sensor, easily produce drift in measuring process, non-linear large and signal a little less than; Adopt the device of capacitance type sensor, stray capacitance and distributed capacitance are larger etc. on the impact of sensitivity and measuring accuracy.And the application of appeal sensor, great majority are all in specific occasion.
Summary of the invention
The object of the present invention is to provide a kind of tongue tube sensor tank gage, after this device detects the liquid level position, send the data to by the instrument of single-chip microcomputer as main control unit, by display screen, information is shown, can adapt to the position measurement of plurality of liquid, and with warning function.
The objective of the invention is to be achieved through the following technical solutions:
A kind of tongue tube sensor tank gage, this tank gage comprises device for storing liquid, linker, tongue tube sensor, instrument case; See through wall to two communicating pipe of peripheral hardware on a sidewall of device for storing liquid, be two communicating pipes up and down and arrange, two communicating pipes was connected with linker; Inner chamber at linker is equipped with the tongue tube sensor, and the tongue tube sensor has upper floating ball and lower ball float; The tongue tube sensor is connected with instrument case by data line; The panel of instrument case is provided with the LCD Chinese characters display screen, mode key, "+" number key, "-" number key and loudspeaker.
Described a kind of tongue tube sensor tank gage, described tongue tube sensor have two ball floats in up and down, and lower ball float is surveyed the minimum point of liquid level, and upper floating ball is surveyed the peak of liquid level.
Advantage of the present invention and effect are:
The present invention utilizes the tongue tube sensor as measurement mechanism, again by the transformation to the tank body tank, when having avoided adopting the inconvenience that other sensors bring, can also measure the higher liquid of temperature, can adapt to the position measurement of plurality of liquid, and just be used for specific liquid unlike other sensors.This device detects the liquid level position and sends the data to by the instrument of single-chip microcomputer as main control unit, by display screen, information shown, and with a kind of metering device of warning function.
