Abstract
The utility model relates to an oxygen flowmeter. The utility model comprises a probe and a host composed of an interface circuit, a shaping circuit, an electronic regulating system, a display and an uninterrupted power supply. The photosensitive tube and the light emitting diode of the probe are respectively installed at two isolation chambers in order to isolate the circuit and a gas path completely. When the oxygen is flowing, the rotor of the probe drives the occulter which is provided with loopholes to rotate, induction signal outputted by the photosensitive tube inputs into the host, and the display displays the cumulative dosage of oxygenous after the shaping circuit shapes and the electronic regulating system justifies by fractional frequency. Because the uninterrupted power supply supplies power, even if the power is cut, the oxygen flowmeter can also continue working. The oxygen flowmeter can also be used as other gaseous flowmeters.
Description
The utility model relates to a kind of measuring apparatus, relates in particular to a kind of oxygen flow meter.
The hospital that carries out concentrated oxygen supply be by the oxygen machine room to each subregion oxygen supply because oxygen terminal that each subregion is installed or the actual oxygen terminal quantity difference of using, each oxygen terminal oxygen consuming amount is fixing in addition, so the actual oxygen consuming amount of each subregion is inequality.At present the glass rotameter that uses is the proportionate relationship according to flow and float lifting height, changes by scale indication instantaneous delivery, need managerial personnel observed and recorded at any time, just can know the accumulation oxygen consuming amount after as calculated, so use very inconvenient.
The purpose of this utility model is to provide a kind of device that can show subregion accumulation oxygen consuming amount at any time.
The utility model is made up of probe and main frame, photosensitive tube in the probe is to the rotation of the induced signal record rotor of light emitting diode, induced signal is input to the shaping circuit of main frame by interface circuit, demonstrates the accumulation oxygen consuming amount with digital form after the adjustment of electronics Adjustment System frequency division.Of the present utility model being characterised in that: photosensitive tube in the probe and light emitting diode place two insulated chambers respectively, circuit and gas circuit are isolated fully, the two ends of rotor of probe is supported on the bearing by apical axis, between two insulated chambers occulter is arranged, the occulter middle part is provided with light hole, and insulated chamber is made with light transmissive material.
Because oxygen is very active, the combustion-supporting gas of a kind of chemical property, so insulated chamber of the present utility model is isolated circuit and gas circuit fully, thereby is particluarly suitable for using in the oxygen pipeline.When flow of oxygen, rotor in the probe drives the occulter that is provided with light hole and rotates, export induced signal behind the light that photosensitive tube reception light emitting diode sends, be input to the shaping circuit of main frame by interface circuit, the rect.p. of shaping circuit output is input to rate multiplier and carries out the frequency division adjustment, supply display directly to demonstrate the cumulative volume of oxygen through adjusted signal, do not need people just to know the accumulation oxygen consuming amount through calculating behind the observed and recorded at any time.Main frame is powered with uninterrupted power source, even oxygen flow meter also can work on when having a power failure.The utility model is not only applicable to show flow of oxygen, is applicable to show other gas usage yet.
