Description

Absolute pressure formula liquid level gauge
Technical field
The utility model is related to a kind of liquid level gauge, and in particular to a kind of absolute pressure formula liquid level gauge.
Background technology
The measurement of liquid level is frequently involved in industries such as agricultural, water conservancy, petrochemical industry, water supply and sewage, environmental protection.It is quiet due to fluid column Pressure is directly proportional to liquid level, therefore can measure the height of liquid level by measuring the differential pressure of liquid column bottom and fluid column surface.Current city The pressure-type liquidometer used on field, generally uses gauge pressure type pressure sensor, this sensor to have two pressure inputs, Pressure sensor is placed in the bottom of fluid column, the pressure of one pressure input direct feeling liquid column bottom, another pressure Input leads to fluid column surface sense by atmospheric pressure by soft wireway, and such liquid level gauge is referred to as gauge pressure transducer formula liquid level Meter.The shortcoming of gauge pressure formula liquid level gauge is:The problems such as wireway is susceptible to block, ruptures, distorts, poor reliability, fault rate is high, Maintenance cost is high.
Utility model content
To solve the above problems, the utility model provides a kind of absolute pressure sensor formula liquid level gauge, without wireway, reduces Failure factor, it is ensured that the reliability and accuracy of measurement.
To achieve the above object, the technical scheme that the utility model is taken is:
Absolute pressure formula liquid level gauge, including first sensor, second sensor sensor, measurement and controller and GPRS transmitting moulds Block (or wireless transmitter module), first sensor, second sensor sensor are connected with the input of measurement and controller, GPRS Transmitter module is connected with the output end of controller, and the first sensor is used to gather the pressure of liquid and the pressure of air, institute Second sensor is stated for measuring atmospheric pressure.
Preferably, the GPRS transmitter modules are by being wirelessly connected with mobile terminal.
The utility model has the advantages that:
Without connecting pipe, the uncertain factor of measurement is reduced, it is ensured that the reliability and accuracy of measurement;Using GPRS Transmitter module (or wireless transmitter module) can check liquid level (water level) real-time measuring data by mobile phone or wireless device at any time, When liquid level drops to designated water level, alarm signal can be sent, be easy to management.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is one structural representation of specific embodiment of the utility model.
Specific embodiment
In order that the purpose of this utility model and advantage become more apparent, the utility model is entered with reference to embodiments Row is further described.It should be appreciated that specific embodiment described herein is only used to explain the utility model, and without In restriction the utility model.
As shown in figure 1, this practicality carries out embodiment there is provided a kind of absolute pressure formula liquid level gauge, including first sensor 1, second Sensor 2, measurement and controller 3 and GPRS transmitter modules 4 (or wireless transmitter module), first sensor, second pass Sensor sensor is connected with measurement and the input of controller, and GPRS transmitter modules are connected with the output end of controller, and described the One sensor is used to gather the pressure of liquid and the pressure of air, and the second sensor is used to measure atmospheric pressure.
The GPRS transmitter modules are by being wirelessly connected with mobile terminal.
The principle of this specific implementation is:Because the pressure of liquid is directly proportional to liquid level, therefore the pressure of measurement liquid can To measure the height of liquid level.First sensor is used to gather the pressure of liquid and the pressure of air.Liquid at a certain temperature Liquid-level pressure be constant, and atmospheric pressure is to become at any time, and the change of atmospheric pressure causes the change of fluid density again, because It is indeterminacy liquid level that this only relies on first sensor, and second sensor 2 is specially to measure atmospheric pressure, is surveyed in measurement process Amount and controller real-time resolving go out each parameter to atmospheric pressure and to density, the influence of temperature, so that it may the height of accurate measurement liquid level. And the data for measuring can be launched by GPRS transmitter modules (or wireless transmitter module), by mobile phone or wireless device just Liquid level (water level) real-time measuring data can be checked.
This specific implementation can be used for the measurement of the water levels such as the irrigation of irrigation and water conservancy deep-well, pond, reservoir, and Fig. 2 is for measuring The example of the water level of deep-well 3, first sensor 1 is arranged in the bottom of deep-well 3, is connected with measurement and controller by wire 5, will examine The output for measuring is measured and controller, second sensor 2 and GPRS transmitter modules or wireless transmission mould to measurement and controller Block is arranged in deep-well mouthful, and second sensor 2 is used to measure atmospheric pressure.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and Retouching also should be regarded as protection domain of the present utility model.
