Abstract
The utility model discloses a kind of flow measurement device, comprise housing, housing both sides are respectively arranged with input end and output terminal, housing upper is provided with measures chamber, measure on chamber and be provided with upper cover, housing is formed with the fluid cavity be communicated with input, output terminal, is provided with impeller in fluid cavity, be separately installed with Hall element and pressure sensor in described measurement chamber, this pressure sensor is communicated with described fluid cavity.In this flow measurement device structure, measuring flow function basis is integrated with pressure sensor also, made it possess to measure the ability of fluid flow and pressure, usable range is wider, to meet the demand of practical application simultaneously.
Description
Technical field
The utility model relates to a kind of measuring apparatus, particularly a kind of flow measurement device.
Background technology
Flow measurement device includes housing, and housing both sides are respectively arranged with input end and output terminal, and housing upper is provided with measures chamber, measures on chamber and is provided with upper cover.Wherein, housing is formed with fluid cavity, is provided with impeller in fluid cavity, and impeller is provided with magnet rotor.Measure in chamber and Hall element is installed.When detected fluid flows through sensor, under fluid matasomatism, the stressed rotation of impeller, magnet rotor rotates thereupon, and its rotating speed is directly proportional to pipeline mean flow rate.The rotation period ground of impeller changes the magnetic resistance value of magnetic loop, the generating period change thereupon of magnetic flux in magnetic test coil, produce the induction electromotive force that frequency is identical with rotating frequency of the blade, after circuit amplifies after testing, carry out changing and processing just can obtaining measured flow value.Under existing application conditions, also need to measure its pressure at the flow measuring fluid simultaneously.But the function ratio of existing flow measurement device is more single, can only measure the flow of fluid, also needing to configure corresponding pressure transducer could meet application demand.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of flow measurement device, can measure its pressure simultaneously, meet application demand at measurement fluid flow.
In order to solve the problems of the technologies described above, a kind of flow measurement device of the present utility model, comprise housing, housing both sides are respectively arranged with input end and output terminal, and housing upper is provided with measures chamber, measures on chamber and is provided with upper cover, housing is formed with the fluid cavity be communicated with input, output terminal, be provided with impeller in fluid cavity, be separately installed with Hall element and pressure sensor in described measurement chamber, this pressure sensor is communicated with described fluid cavity.
As the improvement of technique scheme, in described measurement chamber, also thermistor element is installed.
As the improvement of technique scheme, in described measurement chamber, be provided with the communication module be electrically connected with Hall element, pressure sensor and thermistor element.
As the improvement of technique scheme, cover on described and solar panels are installed.
The beneficial effects of the utility model are: in this flow measurement device structure, measuring flow function basis is integrated with pressure sensor also, made it possess to measure the ability of fluid flow and pressure, usable range is wider, to meet the demand of practical application simultaneously.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is one of structural representation of the present utility model;
Fig. 2 is structural representation two of the present utility model.
Embodiment
