Abstract

The utility model discloses an integral heat meter, which is mainly composed of a water inlet temperature sensor, a backwater temperature sensor, a central processor, a liquid crystal display, a flowmeter, a dry spring tube, a data memorizer and a data communication interface, wherein, the flowmeter, the dry spring tube, the central processor and the data memorizer are encapsulated between an upper shell and a bottom shell, and the central processor is used for forming the flowmeter, the water inlet temperature sensor and the backwater temperature sensor into a whole. The liquid crystal display is arranged on the upper shell, a multi-jet inner shell is arranged in the inner part of the flowmeter, and the water inlet temperature sensor and the backwater temperature sensor utilize three-line temperature sensors having temperature compensation lines. The utility model has the advantages of high precision, high stability, compact structure, beautiful appearance, low cost, etc.

Description

The monoblock type calorimeter

Technical field:

The utility model relates to a kind of measurement instrument, especially a kind of calorimeter.

Background technology:

The calorimeter that uses is the combined hot scale at present, its flowmeter, temperature sensor, central processing unit can be considered independent sector, require the precision of each several part higher, therefore be difficult to be combined into the higher calorimeter of accuracy class, and because flowmeter has adopted the single channel structure, its precision and less stable.Temperature sensor has all adopted two line system temp sensor (no temperature is repaid line), therefore is difficult to guarantee the measuring accuracy of calorimeter when small temperature differentials.

Summary of the invention:

In view of existing defective in the prior art, the utility model provides the compact conformation and attractive in appearance, the lower-cost monoblock type calorimeter of a kind of high precision, high stability.Its technical solution is as follows: the utility model is mainly by the inflow temperature sensor, the return water temperature sensor, central processing unit, LCD, flowmeter, tongue tube, data-carrier store, data communication interface is formed, flowmeter wherein, tongue tube, central processing unit, data-carrier store is encapsulated between upper casing and the drain pan, by central processing unit with flowmeter, the inflow temperature sensor, the return water temperature sensor is formed an indivisible integral body, LCD is arranged on the upper casing, there are multithread bundle structure inner casing, inflow temperature sensor in flowmeter inside, the return water temperature sensor adopts the three-wire system temperature sensor that the temperature compensation line is arranged.

The utlity model has precision height, good stability, compact conformation, attractive in appearance, advantage such as cost is lower.
