Abstract
The present invention relates to a kind of self-calibration water metering equipment based on electromagnetic acoustic composite principle.The present invention includes flowmeter bodies, two electrodes, two transducers and two reflectings surface.Wherein two electrodes are mounted opposite and form electromagnetic flowmeter in flowmeter bodies, and the sound wave that transducer sends gets back to another transducer after two reflective surface, thus forms ultrasonic flowmeter.Electromagnetic flowmeter and ultrasonic flowmeter technology combine by the present invention, adopt electromagnetic flowmeter as flow test units, whether carry out the monitoring of day normal flow, and ultrasonic flowmeter is as monitoring unit, meeting the requirements to the flow measurement error of electromagnetic flowmeter exercises supervision.The present invention has the features such as reliability is high, middle inspection easy to use.
Description
Technical field
The present invention relates to a kind of water metering equipment, a kind of self-calibration water metering equipment based on electromagnetic acoustic composite principle of middle inspection 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 is fast-developing, water consumption far exceeds the ability to bear of water resource.In order to promote reasonable disposition and the efficiency utilization of water resource, nearly ground more than 2 years hydraulic department has started to establish water resource metering supervision Internet of Things.But due to the existence of the accuracy of water resource water metering equipment, long-time stability, the abnormal data feedback processing problem such as not in time, cause Internet of Things actual motion weak effect, the related management work such as water resources taxes collection cannot 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.
Existingly both at home and abroad the research emphasis of the flowmeter of water metering is all concentrated on to how type selecting, how correctly to install and use, how to realize the Remote monitoring of flow meter data.Domestic water conservancy administration department tentatively establishes 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 special flowmeter of water metering, such flow meter specially should be adapted to the general or poor aqueous medium metering of water quality, be suitable for installing in various occasion, with the signal output being convenient to monitor and teletransmission, can carrying out long-range verification or field-checking easily.
Summary of the invention
In order to solve Problems existing in background technology, the object of this invention is to provide a kind of self-calibration water metering equipment based on electromagnetic acoustic composite principle, adopting electromagnetic flowmeter as flow test units, carrying out the monitoring of day normal flow.And ultrasonic flowmeter is as monitoring unit, whether the flow measurement error of electromagnetic flowmeter is met the requirements and exercises 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, itself and actual water intake conduit Flange joint.
Described electrode A is arranged on flowmeter bodies inwall top, and electrode B is arranged on bottom flowmeter bodies inwall, 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 the side of electrode A, is arranged on flowmeter bodies inwall top, and reflecting surface A is housed bottom the inwall relative with transducer A.
Described transducer B is positioned at the side of electrode A, is arranged on flowmeter bodies inwall top, and reflecting surface B is housed bottom the inwall relative with transducer B.
Wherein transducer A and transducer B is positioned at the homonymy of electrode A, and transducer A than transducer B closer to electrode A.
Described reflecting surface A and the reflecting surface of reflecting surface B are mounted opposite.
The beneficial effect that the present invention has is: electromagnetic flowmeter and ultrasonic flowmeter technology combine by the present invention, adopt electromagnetic flowmeter as flow test units, carry out the monitoring of day normal flow, and ultrasonic flowmeter is as monitoring unit, whether the flow measurement error of electromagnetic flowmeter is met the requirements and exercises supervision.The present invention has the features such as reliability is high, middle inspection easy to use.
