Abstract
The utility model discloses a differential pressure type liquid densimeter comprising a pipe body the upper end and the lower end of which are both closed. A pressure sensor is arranged on the pipe body with a constant spacing, a liquid inlet and a liquid outlet are arranged on the pipe body, a drain outlet is arranged below the liquid inlet, and a gas vent is arranged at the top of the pipe. By utilizing the differential pressure type liquid densimeter, the problem that standardization is inconvenient to use is solved. In addition, the differential pressure type liquid densimeter is high in precision, simple to manufacture, low in cost and the like, is suitable for measurement of density of various liquid and has good practicability.
Description
Technical field
The utility model belongs to air-conditioning technical field, is specifically related to the gradiomanometer that a kind of heat source tower system anti-freezing solution measurement of concetration is controlled use.
Background technology
Gradiomanometer is the instrument of measuring fluid density, and it is mainly by housing, synchronous valve, pressure reduction display device, upper lower chamber be connected the parts such as tracheae, liquid capsule and form.This densitometer complex structure, cost of manufacture is high, demarcate inconvenience, and precision is not high, can not meet the user demand that heat source tower system anti-freezing solution measurement of concetration is controlled.
Utility model content
Goal of the invention: for the deficiencies in the prior art, the purpose of this utility model is to provide a kind of gradiomanometer, makes it have the features such as precision is high, manufacture is simple, cost is low, is applicable to the mensuration of various fluid densities.
Technical scheme: for achieving the above object, the technical solution adopted in the utility model is as follows:
A gradiomanometer, comprises the body that upper and lower side all seals; Between the constant spacing of described body, be provided with pressure transducer; On described body, be provided with inlet and liquid outlet; Below inlet, be provided with sewage draining exit; Top at described body is provided with vent port.
Described constant spacing is the fixed range between upper fairlead and lower fairlead.
Described lower fairlead is located on the tube wall between inlet and sewage draining exit.
On described inlet, be provided with temp probe blind pipe.
Described liquid outlet is located on the tube wall between fairlead and body top.
On described body, be provided with zinc coat.
Beneficial effect: compared with prior art, gradiomanometer of the present utility model, has not only solved to use and has demarcated inconvenient problem, and have precision high, manufacture simple, low cost and other advantages, be applicable to the mensuration of various fluid densities, there is good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of gradiomanometer.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the utility model.
As shown in Figure 1, gradiomanometer comprises the body 1 that upper and lower side all seals; Between the constant spacing of body 1, be provided with pressure transducer 4, this constant spacing is the fixed range between upper fairlead 8 and lower fairlead 9.On body 1, be provided with inlet 3 and liquid outlet 2, below inlet 3, be provided with sewage draining exit 5; At the top of body 1, be provided with vent port 7.Wherein, lower fairlead 9 is located on the tube wall between inlet 3 and sewage draining exit 5, and liquid outlet 2 is located on the tube wall between fairlead 8 and body top.On inlet 3, be provided with temp probe blind pipe 6.On body 1, be provided with zinc coat.
This gradiomanometer, measures the pressure difference between spacing by pressure transducer 4, according to formula p=ρ gh, can calculate fluid density.Simply, conveniently, low cost of manufacture, be applicable to the mensuration of various fluid densities.In addition, set temperature probe, and body is carried out to zinc-plated processing, all can revise fluid density, to improve measuring accuracy.
Gradiomanometer of the present utility model, has not only solved to use and has demarcated inconvenient problem, and have precision high, manufacture simple, low cost and other advantages, be applicable to the mensuration of various fluid densities, there is good practicality.
