Abstract

The invention discloses a metering device for non-full pipeline measurement and provides a water flow meter. The conventional ultrasonic time-difference pipeline flowmeter is used as the measurement and application basis; a water level sensor is additionally arranegd at the bottom of the pipelines; and by measurement of water (liquid), a flowmeter processor calculates to obtain the section area of actual passing water (liquid) in the pipelines according to the corresponding water level height and pipeline diameter and multiplies the section area with the measured flow rate in the water (liquid) delivery pipelines to greatly improve measuring accuracy of water (liquid) flow in pipelines, particularly the water flow of non-full pumping pipelines of an underground water motor-pumped well for irrigation.

Description

Non-full pipe road ultrasonic flow meter
Affiliated technical field
The present invention relates to the automatic accurate WT-MSR of ultrasonic flow under the non-full pipe situation in a kind of water delivery (liquid) pipeline.
Figure viewed from behind technology
At present; The ultrasound wave pipeline flowmeter generally is that the flow velocity in water delivery (liquid) pipeline is measured; With the sectional area of pipe flow speed * internal diameter of the pipeline=moment flow, this metering method can only adapt to the mobile situation of full packages water (liquid), but under many circumstances; Can't realize the full packages conveying in water delivery (liquid) pipeline, this has just caused error in dipping.In addition, also there is only a few to adopt ultrasonic sensor to carry out the measurement mechanism of non-full pipe on the market, but, can't measures to small diameter pipeline with near the situation of full packages in view of intrinsic hangover (blind area) characteristic of ultrasound wave at the top of water delivery (liquid) pipeline.So the measurement of non-full pipe road never has suitable can satisfy the automatic measuring device that it accurately measures.
Summary of the invention
In order to overcome the end that covers of using instrument in the above-mentioned application; Improve the measuring accuracy that pipeline water (liquid) is measured; The present invention provides a kind of non-full pipe road to measure WT-MSR, counts the measurement application foundation with existing ultrasound wave time difference method pipeline flow, increases a level sensor in duct bottom; Through measurement to water (liquid) position; The flowmeter processor is calculated actual water (liquid) area of crossing in the pipeline according to the equivalent water level altimeter, multiplies each other according to the flow velocity of measuring in water delivery (liquid) pipeline again, can draw accurate data on flows.
The invention has the beneficial effects as follows, improve the measuring accuracy that pipeline water (liquid) is measured, especially underground water motor-pumped well pumping conduit is irrigated the discharge metering of non-full pipe.

Specific embodiments
When water delivery (liquid) pipeline (1) carries out transporting water (liquid); Flowmeter processor (6) drives the velocity measurement transducer A (3) and the velocity measurement transducer B (4) that are positioned at water delivery (liquid) pipeline (1) two middle side part to be launched each other, receives sound pulse, records water (liquid) flow velocity in water delivery (liquid) pipeline (1) through corresponding computing formula.Simultaneously, flowmeter processor (6) startup is surveyed water (liquid) level sensor (5) and is recorded actual water (liquid) position (2) elevation.Flow processor (6) calculates actual mistake water sectional area according to water (liquid) position (2) data of actual measurement with caliber mutually, calculates mutually with the water that records (liquid) flow velocity again, draws the accurate flow under the non-full pipe state.

Claims (2)

1. a non-full pipe road ultrasonic flow measures device, and its principal character is by transporting water (liquid) pipeline, one group of ultrasonic measurement flow sensor, and a level sensor, a flow metering processor is formed.
2. according to claim 1, it is characterized in that carrying the liquid duct bottom that level sensor is installed.
