The whole gas pressure compensation control device is generally integrated on a circuit board. The control device is extremely small in volume, and a pressure sensor and a valve are also extremely small, so the controller is small in volume on the whole. The control device is extremely convenient to install, and multiple pipeline design proposals can be selected. The signal transmission line of the pressure sensor is arranged in the machine body for directly transmitting signals to a main control module. The interference of external magnet fields, etc on signals is effectively shielded, anti-jamming capability is largely enhanced, and signal transmission reliability and accuracy are ensured. The adoption of microcomputer intelligent control realizes automatic pressure compensation. Proper mathematical models are selected according to measured gas and apparatus types. The measurement of gas flow is more accurate. The utility model has outstanding significance on economic accounting and energy management.
Description
Technical field
The utility model belongs to the gas pressure regulator field, particularly a kind of gaseous-pressure controller.
Technical background
Gas pressure regulator is a kind of instrument that is widely used in gaseous tension control.Because the compressibility of gas has determined its gas density difference under different pressures, by The Ideal-Gas Equation as can be known, the size of gas density and its pressure are proportional, thus gas unit volume quality also with the proportional relation of pressure.So, when the measurement of gas flow, should consider the pressure compensation problem.Common gas meter is to come metered flow according to gas flow in container or pipeline, can appear at gas pressure change under the relative constant temperature and the flow error that produces, can't change pressure compensate.In the occasion that gas weight is had relatively high expectations, it is inaccurate that the result can appear measuring in this metering method, so the common gases metering outfit can't be operated in that pressure changes greatly and to the demanding metering occasion of gas weight.This accurately controls the pressure of gas with regard to requiring, so that make the density of gas remain on steady state.
Summary of the invention
The purpose of this utility model provides a kind of can the compensation automatically gaseous tension in the pipeline, makes the accurate more gaseous tension control device of gas flow measurement.
The technical solution of the utility model is: a kind of gaseous tension control device, comprise controller and high speed valve, described controller comprises main control module, data acquisition module, display module, data memory module, power module, load module, output module, valve driving module and pressure transducer;
