Abstract
The invention relates to a self-calibrating water-intake metering unit based on the composite electromagnetic and ultrasonic principle. The unit comprises a flowmeter body, two electrodes, two transducers and two reflecting surfaces. The electrodes are mounted oppositely on the flowmeter body to form an electromagnetic flowmeter. Acoustic wave emitted by one transducer is reflected by the two reflecting surfaces and returns to the other transducer, thus an ultrasonic flowmeter is formed. The electromagnetic flowmeter technology and the ultrasonic flowmeter technology are combined; the electromagnetic flowmeter serves as a flow test unit for monitoring daily flow; the ultrasonic flowmeter services as a monitoring unit for supervising whether flow measurement errors of the electromagnetic flowmeter are satisfactory or not. The self-calibrating water-intake metering unit based on the composite electromagnetic and ultrasonic principle has the advantages of high reliability, convenience for inspection in use and the like.
Description
Technical field
The present invention relates to a kind of water metering equipment, a kind of water metering of self-calibration based on electromagnetic acoustic composite principle equipment of middle check especially easy to use.
Background technology
Water resource is the social resources of basic natural resources, strategic economic resources, sharing.But along with social economy's fast development, water consumption far exceeds the ability to bear of water resource.For reasonable disposition and efficient utilization that promotes water resource, nearly ground more than 2 years hydraulic department has started to establish water resource metering supervision Internet of Things.But because accuracy, long-time stability, the abnormal data feedback processing of water resource water metering equipment waits the existence of problem not in time, cause Internet of Things actual motion weak effect, the related management work such as water resources taxes collection can't normally be carried out.Therefore, developing a kind of Networkable and be significant at the water resource special measuring equipment of X-ray inspection X, is the basis that water resource metering supervision is implemented.
The research emphasis of the existing flowmeter of both at home and abroad water metering being used all concentrates on type selecting how, how correctly to install and use, how to realize the Remote monitoring of flow meter data.Domestic water conservancy administration department has tentatively been set up remote data transmission and the monitor supervision platform of water draw rate meter or electric energy meter measuring apparatus.Not yet find that there is the development of the flowmeter of water metering special use, such flow meter specially should be adapted to the metering of the general or poor aqueous medium of water quality, suitablely in various occasions, installs, with the signal output of being convenient to monitor and teletransmission, can carry out easily long-range verification or field-checking.
Summary of the invention
In order to solve the problem that exists in background technology, the purpose of this invention is to provide a kind of water metering of self-calibration based on electromagnetic acoustic composite principle equipment, adopt electromagnetic flowmeter as the flow rate test unit, carry out the monitoring of day normal flow.And ultrasonic flowmeter is as monitoring unit, and whether the flow measurement error of electromagnetic flowmeter is met the requirements and exercise supervision.
The technical solution used in the present invention is:
The present invention includes flowmeter bodies, electrode A, electrode B, transducer A, transducer B, reflecting surface A and reflecting surface B.
Described flowmeter bodies is the tubular of both ends open, and it is connected with actual water intake conduit flange.
Described electrode A is arranged on flowmeter bodies inwall top, and electrode B is arranged on flowmeter bodies inwall bottom, and described electrode A and electrode B are two electrodes of electromagnetic flowmeter, and they are on same vertical cross-section.
Described transducer A is positioned at a side of electrode A, is arranged on flowmeter bodies inwall top, in the inwall bottom relative with transducer A, reflecting surface A is housed.
Described transducer B is positioned at a side of electrode A, is arranged on flowmeter bodies inwall top, in the inwall bottom relative with transducer B, reflecting surface B is housed.
Wherein transducer A and transducer B are positioned at the homonymy of electrode A, and transducer A is than the more close electrode A of transducer B.
The relative installation of reflecting surface of described reflecting surface A and reflecting surface B.
The beneficial effect that the present invention has is: the present invention combines electromagnetic flowmeter and ultrasonic flowmeter technology, adopt electromagnetic flowmeter as the flow rate test unit, carry out the monitoring of day normal flow, and ultrasonic flowmeter is as monitoring unit, and whether the flow measurement error of electromagnetic flowmeter is met the requirements and exercise supervision.The present invention has the characteristics such as reliability is high, middle check easy to use.
