Abstract
The utility model discloses a metering device for water or gas, comprising an ordinary mechanical metering device and an electronic integrating meter. The mechanical metering device is connected in series in a pipeline, a signal wheel is arranged on the pointer of the smallest metering scale or the transmission shaft of a dial, a switching element is arranged at the side of the wheel, such as a dry reed pipe, or a magnet sensing diode, a photocoupling switch, etc., and the switching element is connected with the integrating meter through a cable. The utility model has the advantages that the data can be read in situ, and simultaneously, the function of outdoor long-distance transmission data display is added. The centralized and installed integrating meter for displaying data in long distance brings convenience to public utility departments, and provides conditions for the centralized management of computers. In addition, the number is directly used for displaying data, so the reading error is reduced.
Description
The utility model relates to the measuring instrument of fluids such as water or gas, the measuring instrument of particularly civilian tap water or coal gas.
For measuring the consumption of civilian tap water or coal gas, be hinged with water meter and gas meter is absolutely necessary to the user, at present widely used generally is mechanical water meter or gas meter, it must be serially connected on user's the water supply pipe or gas piping, and the reading on the table can only show on the spot and can't teletransmission.The worker that checks meter must enter in the user family and just can check meter, and is subjected to the restriction of building pipe trend, accomplish that the water meter of a building, a building or a residence area or gas meter install in a place very difficulty concentratedly, and this makes troubles for work of public utilities department.In addition, some pointers that generally use show the mechanical type gauging table of reading because the quantity of pointer is many, and the indication deviation is big, very easily makes mistakes during reading of data.
The purpose of this utility model provide a kind of can teletransmission the gauging table of fluids such as the tap water of data or coal gas, it can make the continuous data centralized displaying of water meter or gas meter of a building, a building or a residence area.In addition, data are also directly shown by numeral, reduce reading error.
The utility model mainly is made up of a common mechanical gauging table and an electronics integrator, the machinery gauging table is serially connected on tap water or the gas piping, and on the transmission shaft of the pointer of the minimum metering scale of mechanical gauging table or index dial, adorn signal wheel, the signal wheel is other to be provided with a corresponding signaling switch element, and the signaling switch element is connected with the electronics integrator by cable.All electronics integrators of a building, Building one or a residence area are installed concentratedly, and by one group independently dry cell power supply is provided.Above-mentioned signaling switch element can be a tongue tube or magnetodiode, and the signal wheel is a circle wheel, and its edge is equipped with a magnet steel.When the water or the coal gas that whenever flow through a corresponding measurement unit, transmission shaft drive circle wheel revolves and turns around, the magnet steel at circle wheel edge near and away from tongue tube or magnetodiode once, tongue tube or magnetodiode break-make once and to the electronics integrator are sent a switching signal, and the electronics integrator is just counted once.
Certainly, magnetodiode can also be substituted by other semiconductor magneto sensor, and as magnetic sensitive transistor, Hall element etc., just these semiconductor magneto sensors also need be set up the working power of self.
Equally, above-mentioned signaling switch element can also be a photoelectric coupling switch, and the signal wheel is a circle wheel, and its edge has a breach, the break-make of the edge shape control photoelectric coupling switch light path of signal wheel, and the circle wheel whenever turns around, and the photoelectric coupling switch break-make is once.
Accompanying drawing has been showed embodiment of the present utility model, wherein:
Accompanying drawing 1 is the connection diagram of each parts;
Accompanying drawing 2 is scheme of installations of signal wheel and signaling switch element.
Among Fig. 1, the 1st, mechanical type gauging table, the 2nd, electronics integrator.
Among Fig. 2, the 3rd, the transmission shaft of the pointer of minimum metering scale or index dial in the mechanical gauging table, the 4th, signal wheel, the 5th, the magnet steel at signal wheel edge, the 6th, tongue tube.
Compared with prior art, advantage of the present utility model is promptly to have kept the simple and reliable characteristics of original mechanical gauging table, and the user still can grasp water or the gas consumption of oneself on the spot from showing reading of data, has increased outdoor teletransmission data presentation function simultaneously.The integrator of the long-range video data of installing concentratedly has brought convenience for the work of public utilities department, and provides condition for the computing machine centralized management of civilian tap water or gas measurement from now on.In addition, the electronics integrator is directly used digital displaying data, has reduced reading error.
