Abstract
A square-wave runner ultrasonic water gauge comprises a water gauge housing, a water inlet end transducer, a water outlet end transducer, a water inlet end transducer lining board and a water outlet end transducer lining board, wherein the water gauge housing is a curved housing consisting of a water inflow section, a measurement section and a water outflow section which are sequentially subjected to friction welding, and an integral water inflow, outflow and measurement runner is formed in the housing; the water inlet end transducer and the water outlet end transducer are respectively arranged at the water inlet end and the water outlet end of the measurement section through the water inlet end transducer lining board and the water outlet end transducer lining board; the water inlet end transducer and the water outlet end transducer are connected with a circuit board through signal wires and send and receive ultrasonic waves. The square-wave runner ultrasonic water gauge has the advantages that the ultrasonic signal is strong and stable, the transducers are convenient to mount, the cost is low, the runner is smooth, the fluctuation interference is small, the pressure loss is smaller than reflection, and the measurement section has low probability of impurity accumulation at the highest part of the water channel.
Description
Technical field
The present invention relates to measurement instrument, particularly relate 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.Be divided into according to the arrangement of sound channel: correlation and reflective, ultrasonic propagation direction and the water (flow) direction of correlation are crossed as certain angle, and output signal is little, complex structure, cost are 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, in work, reflecting element is subjected to water pollution fouling to weaken ultrasonic energy.
Summary of the invention
The technical problem to be solved in the present invention 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 arranged on 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, when flowing out measuring section, water (flow) direction is square waveform, and is identical current rectangular section runner.
Advantage of the present invention:
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 measuring section, has saved the part of original packaging transducer, makes whole runner seepage possibility less.
