Abstract
The invention relates to a battery-powered gas mass flowmeter, comprising a gas mass flowmeter and a battery-powered converter connected with the gas mass flowmeter through cables. The battery-powered converter is mainly composed of a control chip, and a battery pack, a display circuit module, a signal input module and a wireless communication module which are connected with the control chip respectively; and the signal input module is connected with the gas mass flowmeter. The invention has the advantages that: the battery-powered gas mass flowmeter is free from cable restriction to greatly broaden application occasions and improve the convenience, has a standard configuration of a conventional lithium battery pack, can continuously work for more than 3 years, and has a longer continuous working period if equipped with a high capacity lithium ion battery pack.
Description
Technical field
The present invention relates to a kind of mass-flow gas meter, particularly disclose a kind of powered battery type combustion gas quality flowmeter.
Background technology
Traditional combustion gas quality flowmeter needs the external power supply of 24VDC or 220VAC, has so just limited the use occasion of this flowmeter, for example, under water or near do not have power supply supply (separately backguy cost too high), make troubles to use.
Summary of the invention
The objective of the invention is to overcome the defective that exists in the prior art, a kind of dispense with outer connecting power, easy to use, the powered battery type combustion gas quality flowmeter that reduces the cable laying cost are provided.
The present invention is achieved in that a kind of powered battery type combustion gas quality flowmeter, comprise the combustion gas quality flowmeter, it is characterized in that: also comprise the powered battery converter that links to each other with the combustion gas quality flowmeter, described powered battery converter major control chip, the electric battery that links to each other with control chip respectively, display circuit module, signal input module, wireless communication module constitute.Signal input module becomes digital signal to be input to the control chip control chip analog signal conversion of combustion gas quality flowmeter 4 ~ 20mA to handle by the display screen output data according to digital signal, and wireless communication module can allow control chip connect data in other equipment calls control chips.
Described electromagnetism group is the lithium battery group.
Described electric battery is responsible for power supply, and control chip is exactly a single-chip microcomputer, and control chip is handled the digital signal that signal input module provides, and the data after handling are shown by display screen, and wireless communication module then is responsible for data communication.
The invention has the beneficial effects as follows: electric battery of the present invention be arranged so that when using that be not subjected to the restriction of cable, use occasion improves greatly, improve convenience, conventional lithium battery group of standard configuration of the present invention, sustainable work is more than 3 years.If adapted high power capacity lithium battery group, continuous working period can be longer.
