Technical background
Employings discrete form such as the temperature sensor in the existing wedge shape flowmeter Flow Measuring System, pressure unit, differential pressure transmitter, wedge flow quantity sensor, three valve groups, valve and connecting pipe, secondary valve, blowoff valve are installed in everywhere, and mutual spacing reaches several meters to tens of meters not to be waited.There are many drawbacks in such Flow Measuring System.
1, the dispersion of each unit of construction system is installed, and has increased installation work-hour and work time cost, mounting material and the Master Cost of system greatly.
2, system reliability is low, maintenance load is big, expense is many, the system failure rate height, and operation ratio reduces.Because pilot pipeline, pipe fitting and valve etc. that each unit measuring-signal of construction system transmits are too many, greatly reduce the reliability of system.
3, The measuring precision is low, and is particularly outstanding in the low-pressure gas flow measurement especially.Because pressure and differential pressure signal connecting pipe, pipe fitting and valve etc. cannot say for sure to demonstrate,prove long-term impermeability, after produce leaking simultaneously again difficulty in time discover.
4, system constitutes complexity, reduces the reliability of system greatly.Because the formation of system reaches several unit, several meters to tens of meters connecting pipes, several valves and fittings, cause the system failure to increase, operation ratio reduces.
Summary of the invention
At the prior art above shortcomings, the purpose of this utility model provides a kind of one-parameter or integrated wedge shape flowmeter of measuring multiple parameters that carries out flow or temperature, pressure flow measurement.
The technical solution adopted in the utility model is such: the integrated wedge shape flowmeter of promptly a kind of one-parameter or measuring multiple parameters comprises differential pressure transmitter, wedge flow quantity sensor, three valve groups, valve and connecting pipe; It is characterized in that: three valve groups are installed on the measuring tube housing of wedge flow quantity sensor, the positive and negative press bond of its positive and negative pressure side and differential pressure transmitter, and be connected with the positive and negative pressure side of the measuring tube of wedge flow quantity sensor by conduit, a valve; Differential pressure transmitter is directly installed on the end face of three valve groups.Thereby constitute one-parameter and measure integrated wedge shape flowmeter

The utility model is owing to the characteristics that described structure has are:
1, integral structure has been simplified the formation of system.It integrates several unit that disperse installation, realizes integrated (type) version that flow measurement (differential pressure) or temperature flow (differential pressure) are measured or pressure flow (differential pressure) is measured or temperature, pressure flow (differential pressure) is measured.
2, save engineering cost.It had both saved installation work-hour and work time cost, saved mounting material and Master Cost again.
3, the reliability height of system, failure rate is low, has reduced maintenance man-hours and maintenance cost.
4, measuring accuracy height, the leakage and the obstruction of pilot pipeline are eliminated or have been significantly reduced in the simplification of system, guarantee accurate measurement.
