Description

Correlation ultrasound wave water meter

Technical field

The utility model relates to a kind of ultrasound wave water meter transducer correlation plumbing installation.

Background technology

In fact the ultrasound wave water meter is equivalent to the base table of our normally used water meter; Only essentic-water-meter is to adopt the mechanical gear drive technology; And the ultrasound wave water meter is to adopt electronic technology, and this is a kind of new technique that is used in cold water meter, remains initial stage at present.

The ultrasound wave water meter is a kind of utensil that discharge is measured; On the principle: utilize electric signal and water flow velocity reverse transfer, the receiving end of signal can receive a vector velocity signal, with the velocity contrast of former electric signal; Can converse discharge flow velocity this moment; If obtain many this flow velocity signals, through statistical computation, accurate discharge in the time of just detecting this.

Existing ultrasound wave water meter generally is to be formed by two intersections and identical pipeline, and wherein one is the current trunk lines, and another root is the signals collecting pipe, and its inside has branch water inner core, two ends that a signals collecting (see figure 1) that comprises transducer is housed.The ultrasound wave water meter of this structure is turned at several places owing to water on the one hand; Produce turbulent flow, cause hydraulic losses big, divide the water length of inner core too short on the other hand; These two factors directly cause measuring accuracy lower, and the flowing water under the incompatible low flow condition of therefore this water meter is measured.

The utility model content

The utility model purpose is to provide a kind of measuring accuracy high, can be applicable to the ultrasound wave water meter of low-speed flow water gaging.

This correlation ultrasound wave water meter that the utility model provides comprises water pipe, divides the water inner core; Two information acquisition heads that contain transducer, said water pipe has only one, divides the water inner core in this water pipe; On water pipe, be respectively equipped with an interface in minute position at water inner core two ends; Be used for the mount message collection head, the transducer of information acquisition head stretches in the water pipe, gathers the vector velocity signal of water and changes into electric signal.

Said transducer is installed in the bucker of a sealing.Bucker is fixed on the mount pad, in this mount pad through wires hole is arranged, and is used to wear the signal wire of transducer.

The utility model is owing to only adopt a water flow pipes, and its water (flow) direction is straight from import to outlet basically, turbulent phenomenon seldom, hydraulic losses is little, and divides the length of water inner core longer, the water flow signal collection is easier, is convenient to communication.Therefore the water meter measuring accuracy is high, and energy measurement is to low pressure rill water gaging.The utility model volume is little in addition, will reduce cost of products.

Fig. 1 is the prior art constructions synoptic diagram.

Fig. 2 is the structural representation of the utility model.

Fig. 3 is an information acquisition header structure signal explosive view.

Embodiment

Fig. 2 and Fig. 3 have reflected the concrete structure of the utility model.As can beappreciated from fig. 2 the utlity model has a water pipe 1, branch water inner core 2 is arranged in this pipeline, two interfaces 11 are arranged on water pipe 1 sidewall, lay respectively at the position at branch water inner core two ends, an information acquisition 3 has been installed respectively on two interfaces 11.

Can find out that from Fig. 3 the information acquisition head mainly is made up of transducer 31 and information acquisition unit 32; Transducer 31 is installed in the bucker 4 of a sealing; This bucker is fixed on the mount pad 5; Through wires hole 51 is arranged on this mount pad, and the signal wire of transducer 31 passes from this through wires hole and is connected on the information acquisition unit 32.

When information acquisition 4 was installed, transducer 31 reached in the flow tube 1 together with the bucker 4 of its outside, and the vector velocity signal of gathering water also changes into electric signal.The outboard end of two transducers is water inlet or water delivering orifices of water pipe 1, and pipeline rectification plug 6 still is housed in this position.

The water that flows into, flows out water pipe 1 carries out the whole ripple of current waveform through pipeline rectification plug 6, discharge more stably is provided, for signal measurement provides stable parameter.Divide water inner core 2 will put in order hydration reason behind the ripple and divide and let out, for the collection of electric signal provides True Data to measure.The signals collecting head will send out, receive the vector velocity signals collecting, discharge information is transmitted in conversion.

The utility model can satisfy the detection of water pipe bore 15～25mm range of size.
