Description

  The present invention relates to a measuring device used for measuring the flow rate and pressure of various gases.

  Conventionally, a device used for measuring this kind of various gases is usually formed by a flow meter 1, a steel pipe 2, an inlet side joint 3, an outlet side joint 4, and a stop valve 5, and gas in the middle of equipment piping. Insert a measuring device and measure. Moreover, it is the structure which comprises a different diameter joint in a steel pipe and an inlet_port | entrance, and the example of a structure of the conventional gas measuring device is shown in FIG.

For example, Patent Document 1 is known as prior art document information relating to the invention of this application.

  However, the conventional gas measuring device has the following problems. That is, in the conventional gas measuring device, since a large number of different diameter joints are used, the size of the measuring device itself is large and the carrying is inconvenient, and only the gas flow rate is measured, and the pressure cannot be measured simultaneously. It was. In addition, the measurement data cannot be saved on the spot.

  The present invention is intended to solve the above-mentioned problems. By storing a flow meter, a pressure gauge, a joint body of various diameters and a data measuring device in a case containing a solid cushioning material, the present invention is easy to carry and portable. It is an object of the present invention to provide a portable gas measuring device that improves the performance, enables the gas flow rate and pressure to be measured simultaneously, and saves the data simultaneously.

  In order to achieve the above object, the present invention has the following configuration.

  The invention described in claim 1 of the present invention particularly includes a flow meter having a gas communication port for measuring a gas flow rate, a pressure gauge having a gas communication port for measuring a gas pressure, and the flow meter or A data measuring device for measuring flow rate or pressure data by electrical connection with the pressure gauge, a power source connected to the data measuring device, and a connecting portion at least one of which is connected to the gas communication port of the flow meter or the pressure gauge. The other is connected to the piping tube, and a plurality of joints with different diameters that can be connected continuously, and the shape of the flowmeter, the pressure gauge, the data measuring device, and the joints with different diameters It is easy to carry to the measurement site by having a case with a solid cushioning material for storing the flowmeter, the pressure gauge, the data measuring device, and the joint body of different diameter in the recess corresponding to For piping of various sizes In addition, since the measuring device is an assembly type and can be set up externally, the insertion time into the pipe can be shortened, and the gas flow rate and pressure can be measured simultaneously. It can be measured and confirmed in real time, and has the effect of being able to save data.

  The portable gas measuring device of the present invention is easy to carry by accommodating a flow meter, pressure gauge, data measuring device, etc. in a case containing a solid cushioning material, and can accommodate various sizes of pipes. Since the apparatus is an assembly type and can be set up externally, the insertion time into the piping can be shortened, the gas flow rate and pressure can be measured simultaneously in real time, and data can be saved and stored.

  In the following, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a main part configuration diagram of a portable gas measuring device according to an embodiment of the present invention, and FIG. 2 is an explanatory diagram of measurement in the device.

  In FIG. 1, a portable gas measuring device includes a large-capacity flow meter (150 to 3000 L / min) 10, a medium-capacity flow meter (50 to 500 L / min) 11, and a small-capacity flow meter (10 to 100 L / min) 12. A case 19 having a solid buffer material 18 having a recess corresponding to each component of the data measuring device 13, the piping tube 14, the joint connector 15 having a different diameter, the pressure gauge 16, and the DC power source 17. Each component is separately disassembled and stored. As a result, the measuring device itself can be stored compactly and can be manually transported, easily carried to the measurement site, can be adapted to any piping size, and the insertion time of the measuring device into the piping can be shortened. Moreover, in the measurement field in a portable place, the gas flow rate to 10-3000 L / min can be measured, and also pressure can be measured.

  Measurement using the portable gas measuring device will be described with reference to FIG. As shown in FIGS. 2 and 3, the data measured by the data measuring device 13 can be saved by the personal computer 20. At this time, the air consumption status of the gas can be quantified in real time in time series, problems such as gas leakage can be instantly revealed, and the effect after the countermeasure can be confirmed at an early stage.

  Furthermore, at the time of measurement, any one of flow rate, pressure, and data storage (save) can be selectively executed. If there are unnecessary measurement items, measurement can be omitted.

  In addition, the gas of the present invention can be used as long as it is a fluid such as nitrogen as well as air such as air.

  In the upper stage of the case 19, the main components of the measuring device are multi-staged on the lower stage or the case lid, and the personal computer 20 is housed using the same solid cushioning material 18 as described above. By comprising, the portability of the said apparatus can be improved further and workability | operativity can be improved.
