Background technology
In Chemical Engineering unit production, the measurement for pond liquid level, the ultrasonic level gage or radar level often used
Meter is installed on the top in pond.For ultrasonic level gage, when measuring the liquid level in pond, ultrasonic pulse is by sensor
（Transducer）Send, sound wave is received or ultrasonic receiver after liquid surface reflects by same sensor, passes through piezo-electric crystal
Or magnetostrictive device is converted into electric signal, and sensor is calculated to test solution by the time between the transmitting and reception of sound wave
The distance in body surface face.For radar level gauge, it is the measuring instrumentss based on time stroke principle, and radar wave is transported with the light velocity
OK, run time can be converted into thing position signal by electronic unit.Probe sends high-frequency impulse and propagated along hawser, works as arteries and veins
Punching reflects when running into surface of material to be received by the receiver in instrument, and distance signal is converted into thing position signal.
But in use, above-mentioned two kinds of instrument all there are the blind area of measurement and the item that should be noted.For
For ultrasonic level gage, can not around there is a strong voltage, heavy current, strong electromagnetic avoids high voltage as far as possible, high current and strong
Electromagnetic interference, its surrounding environment can not have strong motion；For radar level gauge, it is low that measurement range from wave beam touches tank
That point starts to calculate, and under special circumstances, if tank bottom is matrix or taper, can not be measured when thing position is less than this.
The content of the invention
For deficiency of the prior art, a kind of chemical industry pond liquid level measurement device of the utility model offer, simple in construction,
It is easy to use, solve the problems such as measurement blind area be present in existing equipment, not by any external environmental interference, suitable for any liquid level
Measure occasion.
According to design provided by the utility model, a kind of chemical industry pond liquid level measurement device, measured medium is included
The measuring mechanism of pond liquid level, measured medium is filled with chemical industry pond, and described measuring mechanism includes heavy cylinder, differential pressure transporting
Device, for described heavy cylinder in measured medium, heavy cylinder connects setting, differential pressure transporting by capillary with differential pressure transmitter malleation chamber
Device negative pressure cavity connects with ambient atmosphere.
Above-mentioned, described heavy cylinder includes cylinder, and the measuring chamber being arranged in cylinder.
Above-mentioned, described capillary one end and heavy cylinder airtight connection, the other end and the closed company of differential pressure transmitter malleation chamber
Connect.
Above-mentioned, described differential pressure transmitter connects with signal with computer equipment.
Above-mentioned, described differential pressure transmitter uses 1151 type differential pressure transmitters.
The beneficial effects of the utility model：
The utility model is simple in construction, novel in design, reasonable, and the capillary that cylinder top is drawn that sinks is closed to differential pressure transmitter
Malleation, negative pressure are put into heavy cylinder and capillary one end in medium, pond measured medium liquid level and the liquid of heavy cylinder bottom to air
Static pressure caused by the difference in height of position, differential pressure transmitter is passed to by the pressure guiding pipe inner air of capillary, accurate so as to realize
The liquid level change of measured medium is measured, existing measuring apparatus is solved and the situations such as measurement blind area be present, in use, not by outer
The influence of boundary's high voltage, heavy current, high-intensity magnetic field, measurement tank floor shape etc., and easy to operate, it is stable work in work, reliable.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is use state diagram of the present utility model.
Embodiment：
Label in figure, label 1 represent pond, and label 2 represents measured medium, and label 3 represents heavy cylinder, and label 4 represents capillary
Pipe, label 5 represent differential pressure transmitter, and label 6 represents logical ambient atmosphere mouth, and label 7 represents computer equipment.
To make the purpose of this utility model, technical scheme and advantage clearer, clear, below in conjunction with the accompanying drawings and technical side
Case is described in further detail to the utility model.
To overcome deficiency of the prior art, the present embodiment provides a kind of chemical industry pond liquid level measurement device, referring to Fig. 1 institutes
Show, include the measuring mechanism of measured medium pond liquid level, measured medium is filled with chemical industry pond, described measuring mechanism includes
Heavy cylinder, differential pressure transmitter, in measured medium, heavy cylinder is connected described heavy cylinder by capillary with differential pressure transmitter malleation chamber
Set, differential pressure transmitter negative pressure cavity connects with ambient atmosphere.Capillary that heavy cylinder top is drawn is closed to differential pressure transmitter malleation,
