Abstract
The utility model discloses an ultrasonic water meter provided with a square wave type flow channel. The ultrasonic water meter comprises a water meter housing, a water inlet end energy converter, a water outlet end energy converter, a water inlet end energy converter lining plate and a water outlet end energy converter lining plate, wherein the water meter housing is a curved housing formed by friction welding of a water inlet section, a measurement section and a water outlet section in sequence; the complete water inlet, outlet and measurement flow channel is formed in the housing; the water inlet end energy converter and the water outlet end energy converter are arranged at the water inlet end and the water outlet end of the measurement section through the water inlet end energy converter lining plate and the water outlet end energy converter lining plate respectively; and the water inlet end energy converter and the water outlet end energy converter are connected with a circuit board through signal wires to emit and receive ultrasonic waves. The ultrasonic water meter has the advantages as follows: ultrasonic signals are strong and stable; the energy converters are convenient to mount and low in cost; the flow channel is smooth; the fluctuation interference is small; the pressure loss is smaller than the reflecting type pressure loss; and impurities are difficult to accumulate in the highest position of the water flow channel for the measurement section.
Description
Technical field
The utility model relates to measurement instrument, particularly relates to square wave type runner ultrasonic water meter.
Background technology
Existing ultrasonic water meter and ultrasonic heat energy meter mainly are comprised of water flow passage housing, transducer.Arrangement according to sound channel is divided into: correlation and reflective, and ultrasonic propagation direction and the water (flow) direction of correlation are crossed as certain angle, and output signal is little, complex structure, cost high.Can weaken ultrasonic energy and reflective horizontal reflection formula, V-arrangement are reflective, W shape is reflective by the reflector plate reflection supersonic wave, reflecting element is subjected to water pollution fouling to weaken ultrasonic energy in the work.
The utility model content
The technical problems to be solved in the utility model is, provides a kind of ultrasonic signal strong and signal stabilization, and cost is low, the square wave type runner ultrasonic water meter of direct-injection type.
The technical scheme that adopts is:
Square wave type runner ultrasonic water meter comprises water meter case, water inlet end transducer, water side transducer, water inlet end transducer liner plate, water side transducer liner plate.Described water meter case is connected into curved housing through friction welding (FW) successively by inlet segment, measuring section, water exit end, forms complete water-in and water-out and measure runner in housing.Water inlet end transducer and water side transducer are established respectively in the water inlet end of described measuring section and water side, and are installed in water inlet end and the water side of measuring section by water inlet end transducer liner plate and water side transducer liner plate.Described water inlet end transducer and water side transducer link by signal wire and circuit board and send and receive ultrasound wave.
The runner of above-mentioned inlet segment, measuring section, water exit end, make water flow to, water (flow) direction is square waveform when flowing out measuring section, and is identical current rectangular section runner.
Advantage of the present utility model:
1, ultrasonic signal is strong, signal stabilization;
2, transducer is easy for installation, and cost is low;
3, runner is smooth and easy, and fluctuation is disturbed little, and less than the reflective pressure loss, measuring section is at water
The highest point of circulation road is not easy to accumulate impurity;
4, transducer is directly installed on the measuring section, has saved the part of original packaging transducer, makes whole runner seepage possibility less.

Embodiment
Square wave type runner ultrasonic water meter comprises water meter case, water inlet end transducer 5, water side transducer 8, water inlet end transducer liner plate 4, water side transducer liner plate 7.Described water meter case is connected into curved housing through friction welding (FW) successively by inlet segment 1, measuring section 2, water exit end 3, forms complete water-in and water-out and measure runner in housing.The runner of inlet segment 1, measuring section 2, water exit end 3 is identical current rectangularl runner, make water flow to, when flowing out measuring section 2, sectional area and shape are unchanged, velocity flow profile is also unchanged.Water inlet end transducer 5 and water side transducer 8 are established respectively in the water inlet end of described measuring section 2 and water side, and are installed in water inlet end and the water side of measuring section 2 by water inlet end transducer liner plate 4 and water side transducer liner plate 7.Described water inlet end transducer 5 and water side transducer 8 by signal wire 6,9 and circuit board link and send and receive ultrasound wave.
Principle of work
Water enters water meter from inlet segment 1, upwards by inlet segment 1, measuring section 2, form
The passage of square-section enters measuring section 2 square-section passages again, and is backward through measuring section 2
Enter down measuring section 2 and the square-section passage that water exit end 3 forms, flow by water exit end 3 again
Go out water meter, inlet segment 1 and water exit end 3 are by water inlet end transducer 5, water side transducer 8
Waveform, namely the current level enter upwards, level, downwards, level flows out again again.
