VIRTAAMAMITTARIFLOW METER
Jakamalla erotettu patenttihakemuksesta nro 964233.Dissociated from patent application No. 964233.
5 Tämän keksinnön kohteena on virtaamamittari veden, esimerkiksi jäteveden, virtaaman mittaamiseksi.The present invention relates to a flow meter for measuring the flow of water, for example waste water.
Virtaamamittareita käytetään esimerkiksi viemäriverkostoissa mittaamaan jäteveden virtaamia viemäriverkoston eri osissa.Flow meters are used, for example, in sewerage networks to measure effluent flows in different parts of the sewerage network.
10 Tämän keksinnön tarkoituksena on poistaa tunnetun tekniikan epäkohdat ja saada aikaan uudenlainen virtaamamittari sen mukaisesti, mitä oheisessa patenttivaatimuksessa on esitetty.The object of the present invention is to eliminate the drawbacks of the prior art and to provide a new type of flow meter according to the appended claims.
15 Seuraavassa keksintöä selostetaan yksityiskohtaisemmin esimerkin avulla viittaamalla oheiseen piirustukseen, jossa kuviot la - le esittävät keksinnön mukaista virtaamamittaria.In the following, the invention will be explained in more detail by way of example with reference to the accompanying drawing, in which Figures 1a to la show a flow meter according to the invention.
Kuvioissa la - le esitetyssä, keksinnön mukaisessa virtaama-20 mittarissa mitataan pintaveden virtausnopeus sekä pinnankor-keus viemäriputkessa 1. Kuviossa la, joka esittää mittaria edestä päin, näkyy esimerkiksi teräslankaa oleva runko 10, . . joka on taivutettu ylhäältä yhteen ja keskeltä levitetysti, ja jonka alapää on upotettu putkimaisen akselin 11 reikiin. 25 Sen lisäksi teräslanka 10 on painettu kahdessa vierekkäisessä, sivulta katsottuna pyöreässä ponttoonissa 12a, 12b olevaan uraan ja täytetty uretaanilla 13.A flow meter 20 according to the invention, shown in Figures 1a to 1a, measures the surface water flow rate and the surface level in the drain pipe 1. Fig. 1a shows a front view of a gauge steel wire 10, for example. . which is bent from top to center and spread out in the middle, and whose lower end is embedded in the holes of the tubular shaft 11. In addition, the steel wire 10 is embossed in two adjacent grooves, viewed from the side, in a circular pontoon 12a, 12b and filled with urethane 13.
f Ponttoonien 12a, 12b tehtävänä on pitää mittari veden pin- 30 nalla siten, että akselilla 11 oleva siipiratas 14 pyörii veden pinnalla. Ponttoonit 12a, 12b ovat esimerkiksi styrox-muovia. Ne ovat sivusuunnassa pyöreitä, jottei ke1lumissyvyys muutu vesimäärän ja siitä johtuvan kulmamuutoksen takia. Ponttoonien kuviossa la esitetyllä muotoilulla (sisäänpäin 2 105290 suippenevat) on tarkoituksena saada ohjattua putken pohjalla oleva sakka ponttoonien alta.f The function of the pontoons 12a, 12b is to hold the meter on the water surface such that the impeller 14 on the shaft 11 rotates on the water surface. The pontoons 12a, 12b are, for example, styrox plastic. They are laterally circular so that the roll depth does not change due to the amount of water and the resulting angle change. The design of the pontoons shown in Fig. 1a (inwardly 2 105290 tapers) is intended to direct the sediment at the bottom of the tube under the pontoons.
Siipirattaassa 14 on esimerkiksi akryylimuovia olevat siivet 5 15, joiden muoto on sovitettu ponttoonien välissä olevan aukon muotoon siten, että siivet levenevät ulospäin. Niiden päissä on magneetit 16, joita lukee siipien yläpuolella oleva, magneettikenttään perustuva lukija 17, joka kytketään edelleen ohjausjärjestelmään.The impeller 14, for example, has wings 5 15 of acrylic plastic, the shape of which is adapted to the shape of an opening between the pontoons so that the wings extend outwards. At their ends are magnets 16, which are read by a magnetic field reader 17 located above the wings, which is further connected to the control system.

Rungon yläpäässä on pystysuuntainen alumiiniputki 18, jonka päästä lähtee pystysuuntainen metallilanka 19, joka on ylä-päästään kytketty säätövastukseen 20, jonka avulla saadaan kulma, jossa mittari ui, kuten on esitetty kuviossa Ib, joka 15 esittää mittaria sivulta. Mittaamalla säätövastuksen 20 vastus saadaan kulma, jonka avulla voidaan laskea pinnan korkeus. Pinnan korkeuden avulla voidaan laskea segmentin ala. Tilavuusvirta saadaan kertomalla segmentin ala veden virtausnopeudella. Säätövastus on liitetty vaakasuuntaiseen ohjain-20 varteen 21, joka työnnetään mitattaessa viemäriputken 1 yläosaan (kuv. le). Ohjainvarsi 21 on edelleen liitetty pys-• tysuuntaiseen varteen 22. Veden virtaussuunta on esitetty nuolella kuviossa Ib.At the upper end of the body is a vertical aluminum tube 18, from which ends a vertical metal wire 19 connected at its upper end to an adjusting resistor 20 to obtain an angle at which the gauge floats, as shown in Fig. Ib, which shows the gauge from the side. By measuring the resistor of the adjusting resistor 20, an angle is obtained which enables the height of the surface to be calculated. The surface height can be used to calculate the area of the segment. The volume flow is obtained by multiplying the area of the segment by the flow rate of the water. The adjusting resistor is connected to a horizontal guide-arm 20, which is inserted into the upper part of the drain pipe 1 when measuring (Fig. Le). The guide arm 21 is further connected to the vertical arm 22. The direction of water flow is shown by the arrow in Fig. Ib.
25 Alan ammattimiehelle on selvää, että keksinnön eri sovellu-tusmuodot eivät rajoitu yksinomaan edellä esitettyyn esimerkkiin, vaan ne voivat vaihdella jäljempänä esitettävien patenttivaatimusten puitteissa.It will be apparent to one skilled in the art that various embodiments of the invention are not limited to the above example, but may vary within the scope of the following claims.
