Description
Technical field
This utility model is related to a kind of liquid level emasuring device, specially a kind of differential pressure level transmitting of measurable stratified density
Device.
Background technology
At present, known differential pressure liquid level transmitter is the height two ends setting mounting flange outside tested tank body, by method
The blue teletransmission measurement apparatus for installing differential pressure liquid level transmitter, teletransmission measurement apparatus are by capillary tube by pressure conduction to differential pressure liquid level
Liquid level signal output is changed by operational amplification circuit after the sensing unit of transmitter and realizes measurement.As the method is to tested
Tank body integrally carries out level gauging, when the measured medium in tested tank body is made up of Multiple components, when density not can determine that, this
Plant differential pressure liquid level transmitter and accurate liquid level information just cannot be provided.
The content of the invention
In order to overcome existing differential pressure liquid level transmitter for the limitation of the level gauging that medium mixes, this practicality
A kind of differential pressure liquid level transmitter of measurable stratified density of new offer.
This utility model adopts the following technical scheme that realization：A kind of differential pressure level transmitting of measurable stratified density
Device, including the transmitter central arithmetic unit that tested tank body top is arranged on by ring flange, transmitter central arithmetic unit
Data collection terminal mouth is connected with the data cable in tested tank body, is from top to bottom sequentially connected with most on data cable
High level differential pressure pick-up, at least one layering liquid level differential pressure pick-up and minimum liquid level differential pressure pick-up.
The closed metal connection pillar in lower end is provided with outside described data cable, for ensureing cable safety and defending
It is raw.
During measurement, each differential pressure pick-up is directly inserted in measured medium, and the minimum liquid that measured medium should be expected
It is each on position and highest liquid level that minimum liquid level differential pressure sensor/sensor and highest liquid level differential pressure pick-up are set, according to being arranged on highest
Just the density of measured medium at the position can be calculated with each layering liquid level differential pressure pick-up in the middle of minimum liquid level, and then
The whole accurate density for filling measured medium is calculated, while measurement obtains the liquid level signal of measured medium.
Compared with prior art, the differential pressure liquid level transmitter of this measurement stratified density can be applicable to medium mixing
Level gauging occasion, obtains tested tank body accurate density, liquid level information in real time, realizes intelligent measure, information system management, this reality
With new structure is simple, reasonable in design, easy to operate, measurement performance is stable, with good application value.

Specific embodiment
The present invention is further described with example below in conjunction with the accompanying drawings, but protection domain of the present utility model not only limits to
In embodiment.
A kind of differential pressure liquid level transmitter of measurable stratified density, as shown in figure 1, being arranged on quilt including by ring flange 1
The transmitter central arithmetic unit 3 on 2 top of tank body is surveyed, the data collection terminal mouth of transmitter central arithmetic unit is connected with positioned at tested
Data cable 4 in tank body, is from top to bottom sequentially connected with highest liquid level differential pressure pick-up 5, at least on data cable
One layering liquid level differential pressure pick-up 6 and minimum liquid level differential pressure pick-up 7.The quantity of layering liquid level differential pressure pick-up and position
Put, according to being determined needed for measurement, each layering liquid level differential pressure pick-up uniformly can also pinpoint arrangement, be easy to meter
Calculate.The quantity that liquid level differential pressure pick-up is layered in the present embodiment is three.The closed gold in lower end is provided with outside data cable 4
Category connection pillar 8.
In Fig. 1, the differential pressure liquid level transmitter that this utility model is related to is mounted on tested tank body, by gold by ring flange
Category connection pillar is connected with 5 differential pressure pick-ups, and wherein minimum liquid level differential pressure pick-up should be close to tank as far as possible according to measurement demand
Body low side, highest liquid level differential pressure pick-up should be close to tank body top as far as possible, while according to needed for measurement, three are layered liquid level differential pressures
Sensor uniformly can also pinpoint arrangement, be easy to calculate.
By taking minimum liquid level differential pressure pick-up as an example, differential pressure Δ P=P2-P1, when measured medium liquid level occurs to become in tested tank body
During change, P1 and P2 are changed therewith, but differential pressure Δ P is invariable, meanwhile, as the differential pressure pick-up high-low pressure of building block
The distance between side is that h is constant, it is possible to be calculated measured medium density p 1=P/ for covering the differential pressure device（g*h）.Equally,
When the measured medium of different densities is injected in tested tank body, three layering liquid level differential pressure pick-ups and highest liquid level differential pressure are sensed
Device can measure the density of the measured medium at the sensing unit immediately, then connect the data cable in pillar by metal
Transmitter central arithmetic unit is transmitted a signal to, finally with 4～20mA signal outputs.It is also possible to be sensed by each differential pressure
The density value that device is obtained is calculated the average density of measured medium, for the tested tank body direct liquid level of direct measurement.
