Description
Technical field
The utility model belongs to a kind of high-precision intelligent contactless level sensor transmitter device, relates in particular to a kind of bubble level measurement device.
Background technology
The floodometer of resistance Continuous Tracking formula commonly used is the electrode that two fixed ranges are installed on sounding rod, with the water resistance of two an interpolars brachium pontis as balanced bridge.But water resistance is subjected to the influence of water temperature and water quality big, thereby makes its measuring accuracy be subjected to the water temperature and quality variable effect bigger.China's utility model patent communique disclosed detection type multiple spot water level synchronous measuring apparatus on January 29th, 2003, Granted publication CN2533452Y, send control signal by computing machine to stepper motor, the chaining pin that drives sensor moves up and down, according to the height of step number and step pitch calculating water level.But install, safeguard inconvenience, influenced by geologic condition, usable range is limited.The intelligent bubble water level gauge of domestic production enterprise does not all also have matured product at present, and the air bubble type water level meter of external import not only costs an arm and a leg, and delivery cycle is longer, is difficult to satisfy the home market needs.
Summary of the invention
The purpose of this utility model provides a kind of installation, easy to maintenance, and operation, networking flexibility are stable, reliable, the air bubble type water level meter that precision is high.
The purpose of this utility model is achieved in that a kind of air bubble type water level meter, it comprises measures tracheae, pressurizer, measurement source of the gas, survey sensor and intelligent controller, measuring tracheae one end contacts with water, the other end is connected with pressurizer, measurement divides two-way to communicate with the pressure transducer of pressurizer and the measurement tracheae that feeds under water respectively with source of the gas, survey sensor is connected with pressurizer, realizes that the intelligent controller that on-site parameters correction and setting, communication modes are selected is connected with survey sensor.Pressurizer is a pressure vessel, the pressure transducer that setting and measurement link to each other with source of the gas in it.
It is main sensing element that the utility model utilizes high-precision Honeywell pressure transducer, is applicable to the collection and the transmission of waterlevel data, and can realize that on-site parameters correction and setting, communication select.This water level gauge need not to build the water level well, and is easy for installation, is widely used in various landform and weather conditions.It has installation, easy to maintenance, operation, networking flexibility, and stable, reliable, characteristics such as precision height are widely used in the water level monitoring in the telemetry system.

Embodiment
Below in conjunction with drawings and Examples present embodiment is further described.
A kind of air bubble type water level meter, it comprises measures tracheae 1, pressurizer 2, measurement with source of the gas 3, survey sensor 4 and intelligent controller 5, measures tracheae 1 one ends and contacts with water, and the other end is connected with pressurizer 2.Pressurizer 2 is a pressure vessel, the pressure transducer that setting and measurement link to each other with source of the gas 3 in it.Measure with 3 fens two-way of source of the gas and communicate with the pressure transducer of pressurizer 2 and the measurement tracheae 1 that feeds under water respectively, survey sensor 4 is connected with pressurizer 2, realizes that the intelligent controller 5 that on-site parameters correction and setting, communication modes are selected is connected with survey sensor 4.
Principle of work: will measure with source of the gas 3 is that nitrogen in the gas-holder is by behind the reduction valve, divide two-way in pressure transducer and feeding tracheae under water, to carry respectively, water in the tracheae is slowly discharged, meanwhile pressure transducer is because the effect that is under pressure produces certain output, when the gas in the breather line reaches mobile equilibrium, be positioned at waterline below 6 under water the pressure that bears of gas tube orifice be delivered on the pressure transducer through tracheae.When the pressure that pressure and pressure transducer bore of gas tube orifice under water equates, deduct atmospheric pressure value with this force value, can obtain the fine pressure value of height of water level, thereby record out the water level value of variation.
Pressure transducer and pressure signal processing unit: the collection of pressure criteria signal and processing.
Data acquisition and processing (DAP) unit: be used for collection, calculating and deal with data, parameter correction, data storage, switching value control, waterlevel data collection and transmission, communication transmission and touch menu management and parameter storage etc.
Power supply unit: the power supply unit of whole instrument is to be powered to the instrument to collect unit by the high-precision power that the 12V direct supply that the outside provides converts 5V to.Owing to consider the continuity of power supply during this instruments design, also be provided with the power supply unit of DC power supply unit and clock circuit.
Input and output and display unit: adopt 3.7 cun touch-screen to show in real time and control, the calling and revising of real-time demonstration water level and all functions menu.
Cabinet and connector: cabinet is the aluminium alloy sealed cabinet, has firm, sealing, durable, antidetonation, resistance to compression, electrostatic prevention, advantage such as damp proof.Pipe adapter is used for the instrument internal gas circuit and connects, and its sealing property is good.Connector has, and DB4 core, aviation DB3 core plug are used for power supply input and and upper machine communication.
Upper machine communication and interface software: upper machine communication mainly is to gather the handled signal of main frame and by corresponding communications protocol signal is passed to host computer, interface software is that the data of data processing unit are divided on the interface that different modules directly is presented at computing machine, and can store data, printing etc.
It is main sensing element that the utility model adopts high-precision Honeywell pressure transducer, is applicable to the collection and the transmission of waterlevel data.And can realize on-site parameters correction and characteristics such as setting, communication selection.This water level gauge need not to build the water level well, and is easy for installation, is widely used in using as level sensor under various landform and the weather conditions.
