Abstract

A kind of new method that expansion flow measurement range is balanced using hot type of the present invention is related to a kind of flowmeter, is made up of balance flow meter, thermal gas sensor and intelligent flow-integrating instrument etc..It is characterized in that the detection method by installing the thermal gas sensor that can detect minute gas flow additional on balance flow meter table body, expands the measurement range of original balance flow meter.A kind of described hot type balance flow meter is measured under the control of intelligent flow-integrating instrument when the flow of medium is smaller by thermal gas sensor, is measured when flow is larger by balance flow meter and the result of measurement is carried out into data processing and flow indication.

Description

It is a kind of that the new method for expanding flow measurement range is balanced using hot type
The present invention relates to a kind of detection of gas flow rate method, and balance flow meter and hot type are used more particularly, to one kind The new method of gas sensor compound detection gas flow.
First, prior art situation and existing defects
When the 1st, using balanced flow measuring gas flow, less than 30% does not do gauge check in gamut scope, Less than 30% range of flow can not ensure the degree of accuracy.
If the 2nd, to detect low discharge, balance aperture must very little, now produce the larger pressure loss, flowmeter is in itself Consume substantial amounts of energy.
2nd, technical scheme
The present invention is directed to drawbacks described above, it is proposed that one kind is based on balance flow meter and thermal gas sensor compound detection gas The new method of body flow.
The technical solution of the present invention is, using balance flow meter and thermal gas sensor compound detection gas flow New method, it by balance flow meter, heating type gas sensing and intelligent flow-integrating instrument form;Described one kind is put down using hot type Weighing apparatus expands the new method of range of flow, is to install thermal gas sensor additional in the front end of balance, adds in the upper end of balance flow meter Intelligent flow-integrating instrument is filled, is measured by thermal gas sensor when flow is smaller, is entered when flow is larger by balance flow meter Row measurement, this hot type balance composite detection method expand range of flow, and measurement result is entered line number by intelligent flow-integrating instrument According to processing and display.
Technical scheme includes:
1. balance flow meter;
2. thermal gas sensor;
3. intelligent flow-integrating instrument.
3rd, compared with prior art, advantages of the present invention
Compared with prior art, its advantage and good effect are the present invention:
1st, in gamut scope 100% so that gauge check can be done, it ensure that the degree of accuracy in gamut range of flow;
2nd, thermal gas sensor can detect tiny flow quantity, and balance aperture does not have to very little, this caused pressure loss With regard to small, flowmeter consumed energy itself is with regard to small.
4th, accompanying drawing and explanation
Fig. 1 is the cross-sectional view of the present invention;
Fig. 2 is the left view of the present invention.
In Fig. 1 shown in label:1st, balance flow meter, 2, thermal gas sensor, 3 intelligent flow-integrating instruments.
Embodiment:
Present invention generally provides a kind of new method that expansion flow measurement range is balanced using hot type, it is by balance flow meter 1st, heating type gas sensing 2 and intelligent flow-integrating instrument 3 form;A kind of described new side that expansion range of flow is balanced using hot type Method, is to install thermal gas sensor 2 additional in the front end of balance plate, and intelligent flow-integrating instrument is installed additional in the upper end of balance flow meter 1 3, measured by thermal gas sensor 2 when flow is smaller, measured when flow is larger by balance flow meter 1, this heat Formula balance composite detection method expands range of flow, and measurement result is carried out data processing and display by intelligent flow-integrating instrument 3.
This invention expands the flowmeter with combined type detection method of flow measurement range using hot type balance, ensures The degree of accuracy in gamut range of flow, the caused pressure loss is small, flowmeter consumed energy itself is small.
