Description
Technical field
This utility model is related to a kind of air bubble type liquid level gauge, and in particular to a kind of to have multiple-working mode (backup, high speed
Smooth, self checking etc.) air bubble type liquid level gauge, belong to fluid level measuring device technical field.
Background technology
Air bubble type liquid level gauge, using normality air, Jing air filters, after air pump, check valve, air chamber, a point two-way is passed respectively
To in the measurement trachea under pressure transducer and fixative, based in the gas container of a sealing, each point pressure is equal, such as
Fruit gas-liquid boundary is just in the mouth of pipe, and gas does not flow, or does not flow substantially (effervescent), then the mouth of pipe of ventilating under liquid
The hydrostatic pressing of the air pressure at place and the point is equal, and when equal with the air pressure in breather, directly can sense on pressure transducer
To under liquid, the hydrostatic pressing value of blow vent, deducts atmospheric pressure value with this pressure value, you can obtain the fine pressure value of liquid level, so as to
Measure level value.
Existing air bubble type liquid level gauge is had the following disadvantages when in use：Pressure when air pump exports the gas with the presence of pressure
Slight amplitude change, cause measurement result not accurate, air pump works long hours and is easily damaged, make liquidometer cannot normal work,
Measurement data is lacked.
Utility model content
For the deficiencies in the prior art, this utility model provide it is a kind of have multiple-working mode (backup, at a high speed it is smooth,
Self checking etc.) air bubble type liquid level gauge, on the one hand ensure level gauging work effectively, it is stable, on the other hand improve measurement accurate
Degree.
This utility model is implemented by the following technical programs：A kind of bubble type liquid level with multiple-working mode
Meter, including multiple air pump paths in parallel and MCU module, wherein each air pump path is connected with trachea, each air pump path
It is middle that there is air pump and electromagnetic valve respectively；The MCU module periphery is connected with storage device, display device, alarm device, Working mould
Formula switching switch and differential pressure pickup, the differential pressure pickup for being connected with trachea, the MCU module again respectively with each gas
Air pump, electromagnetic valve connection in pump path；Air pump state monitor is connected with each air pump, is connected on each electromagnetic valve
There is electromagnetic valve state monitor, the air pump state monitor and electromagnetic valve state monitor are connected with MCU module respectively.
Relative to prior art, the technique effect that this utility model has：This utility model improves existing bubble type liquid
The deficiency of position meter, effectively improves the service life of such liquidometer, shortens time of measuring, improve accuracy of measurement, extend nobody
Operating time on duty, and different mode of operations can be switched according to measurement requirements of one's work, such as backup, at a high speed it is smooth, from
Verification.
Description of the drawings
Fig. 1 is a kind of structured flowchart of the air bubble type liquid level gauge with multiple-working mode of this utility model.
Specific embodiment
A kind of air bubble type liquid level gauge with multiple-working mode as shown in Figure 1, including multiple air pump paths in parallel
And MCU module, wherein each air pump path is connected with trachea, respectively with air pump and electromagnetic valve in each air pump path；Institute
State MCU module periphery and be connected with storage device, display device, alarm device, mode of operation switching switch and differential pressure pickup, institute
Differential pressure pickup is stated for being connected with trachea, the mode of operation switching switch is for switching backup, smooth, self checking three at a high speed
Mode of operation is planted, the MCU module is connected with the air pump in each air pump path, electromagnetic valve again respectively；Connect on each air pump
Be connected to air pump state monitor, be connected with electromagnetic valve state monitor on each electromagnetic valve, the air pump state monitor and
Electromagnetic valve state monitor is connected with MCU module respectively.
In back-up job pattern, only one air pump participation work, remaining air pump are rested, when air pump state monitor is sent out
When the air pump that now works is abnormal, enables automatically another air pump and work, complete measurement, and send abnormality alarming, effectively improve bubble
Formula liquidometer length of service and reliability.
In the smooth mode of operation of high speed, MCU controls 2 or multiple air pumps are worked and phase complements simultaneously, can survey
When measuring deeper liquid level, it is rapidly reached air pressure balance and enters measuring state, and air-flow shake is smoothed out, and improves certainty of measurement.
In self checking mode of operation, MCU substeps control 2 or multiple air pumps work, and independent measurement is carried out in the short time,
And compare measurement result, the outputting measurement value after arithmetic mean if measurement result is in error permissible value, if measuring result error
It is larger, remeasure, effectively improve certainty of measurement.
