Problems solved by technology

However, the currently commonly used standard orifice flowmeters have only one aperture to flow out, while the other two of the orifice plates have eddy currents due to structural reasons, and all differential pressure flowmeters currently used have straight pipe requirements, which results in an The space is very large, resulting in increased product additional costs
In addition, the corrosion resistance has not completely solved the problem fundamentally.

Abstract

The invention belongs to the technical field of IT (Information Technology) industry, and particularly relates to a ZC intelligent differential pressure balancing flowmeter. The intelligent differential pressure balancing flowmeter comprises a pressure sensor, a temperature sensor and a display and is characterized in that a dual self-locking protection regulating valve is arranged at the front end of a throttling element; the front part and the rear part of the throttling element are respectively provided with a pressure tapping ring; the pressure sensor is arranged at the front end of the throttling element; the temperature sensor is arranged at the front end of the throttling element; a capacitance-type pressure difference capsule sensor is connected with the rear end of the throttling element; each parameter signal line is connected with a central processing unit; and the central processing unit is connected with the display. The invention can obviously eliminate the vortex phenomenon generated at both sides of the throttling element and is inimitable by other throttling elements. Moreover, the flowmeter has strong rot resistance and low purchasing cost and can realize bidirectional flow measurement. The high-intelligent meter integrating three elements of pressure, temperature and flow is powered by a lithium battery, does not generate pollution and realize bidirectional flow. The intelligent differential pressure balancing flowmeter has the precision up to 0.3 percent, reaches the world advanced level and fills the domestic blank.

Description

technical field [0001] The invention belongs to the technical field of IT industry, in particular to a ZC intelligent differential pressure balance flowmeter. Background technique [0002] At present, instruments and meters in our country are all classified into the IT industry, which belongs to the industry supported by the state. However, the currently commonly used standard orifice flowmeters have only one aperture to flow out, while the other two of the orifice plates have eddy currents due to structural reasons, and all differential pressure flowmeters currently used have straight pipe requirements, which results in an The ground space is very large, resulting in increased product additional costs. In addition, the corrosion resistance has not completely solved the problem fundamentally. Contents of the invention [0003] The present invention provides a ZC intelligent differential pressure balance flowmeter aiming at the problems existing in the above-mentioned pri...
