Abstract

Flottörfri relativ och absolut vattennivåmätarprobDet som är signifikant för denna probe är att:Probens form utan rörliga delar möjliggör nedsänkning i brunn tillsammans med slangar wire och övriga elkablar, utan att trassla in sig och fastna i dessa, vid kalibrering, montage och demontage. Lätt att avläsa hur långt proben är nedsänkt i brunn genom att räkna av avståndet till nästa märkning (7) på kabel (9).Kan användas för både relativa och absoluta mätningarGenom att avståndet mellan mätpunkterna (2) är dubbelt så stort runt referensläget (6) erhålles en linjär mätskala även runt referensläget.De mått och antal mätpunkter som anges på bifogad ritning är endast typiska och anpassas till önskad mätsträcka och upplösning.Float-free relative and absolute water level gauge probe What is significant about this probe is that: The shape of the probe without moving parts enables immersion in a well together with wire hoses and other electrical cables, without getting entangled and stuck in them, during calibration, assembly and disassembly. Easy to read how far the probe is immersed in the well by calculating the distance to the next marking (7) on cable (9). Can be used for both relative and absolute measurementsBy the distance between the measuring points (2) is twice as large around the reference position (6 ) a linear measuring scale is also obtained around the reference position. The dimensions and number of measuring points indicated in the accompanying drawing are only typical and are adapted to the desired measuring distance and resolution.

Description

Beskrivning 1930369-2 Flottörfri relativ och absolut vattennivåmätar probe för borrade brunnar Problem som denna probe löser. Description 1930369-2 Float-free relative and absolute water level gauge probe for drilled wells Problems that this probe solves.

Det är mycket svårt att mäta förändring av vattennivå i brunnar efter det att pumpanordninginstallerats med slangar, upphängningsanordning samt elkabel till pumpen. It is very difficult to measure the change in water level in wells after the pump device has been installed with hoses, suspension device and electrical cable to the pump.

Proben (1) är tillverkad av icke ledande material.En flerledad elektrisk kabel (9) har sina ändar anslutna till var sin ledande punkt på proben. The probe (1) is made of non-conductive material. A multi-conductor electrical cable (9) has its ends connected to each conductive point on the probe.

Avståndet mellan de ledande punkterna(2) beror på den upplösning som önskas och antalet ledandepunkter, ger önskat mätområde. The distance between the conductive points (2) depends on the desired resolution and the number of conductive points, giving the desired measuring range.

Mellan den nedersta ledande punkten Common (8) och de övriga mäts konduktiviteten ivattnet.Man kan på så vis avgöra vid eller mellan vilka ledande punkter aktuell vattennivå befinner sig.Rellativ mätning Mätproben(1) sänks ner till vattennivån. Efter det att indikeringen för -30 cm, -20cm, -10cm och +10cm indikerats, lyfter man upp mätproben 10 cm. Vattennivån kommer då att ligga mellan -10 och+10 cm (referensläge = Ocm). Proben är nu kalibrerad och en relativ ökning och minskning av aktuellvattennivå kan då följas. Between the lowest leading point Common (8) and the others, the conductivity in the water is measured. It is thus possible to determine at or between which leading points the current water level is. Relative measurement The measuring probe (1) is lowered to the water level. After the indication for -30 cm, -20 cm, -10 cm and + 10 cm has been indicated, lift the measuring probe 10 cm. The water level will then be between -10 and + 10 cm (reference position = Ocm). The probe is now calibrated and a relative increase and decrease in current water level can then be followed.

Absolut mätning Kabel är märkt med |ängduppgift(7) från referensläge(6), på lämpliga avstånd. Absolute measurement Cable is marked with | meadow information (7) from reference position (6), at suitable distances.

Det gå då lätt att avgöra nivån på aktuell vattennivå iförhållande till annan känd punkt.Option (4) Om antalet ledare i probe blir omfattande går det att minimera antalet trådar i kabel genom attomvandla dessa till seriell form innan dessa avläses.It is then easy to determine the level of the current water level in relation to another known point. Option (4) If the number of conductors in the probe becomes extensive, it is possible to minimize the number of wires in the cable by converting them to serial form before reading them.

Claims (1)

1. Vattennivåmätarproben är en anordning för mätning av vattennivån i borrade brunnar genomskillnaden i konduktivitet emellan vatten och luft. Enheten består av en mätkropp (1) med ett antal elektriska mätpunkter(2) som är fördelade längsmätkroppen (1). De individuella mätpunkterna är varför sig anslutna till en elektrisk ledare som i sinandra ände är gemensamt ansluten till en flerpolig kontakt(3). Antalet mätpunkter på vattenmätarproben (1) är beroende på den mätsträcka som avses samtvilken upplösning som önskas. Om antalet mätpunkter på vattenmätarproben blir ansenlig kan man omvandla informationen frånmätpunkterna till seriell information (parallell till seriell omvandling) (4), för att minimera antaletledare. Vattenmätarproben kännetecknas av en avlång mätkropp (1) och en flertrådig kabel. Övergång mellan kabel och mätkropp utgöras av en konisk del (5) som förhindrar attvattenmätarproben fastnar mellan kablar, wirar och slangar, vid demontage ellerjustering.1. The water level meter probe is a device for measuring the water level in drilled wells through the difference in conductivity between water and air. The unit consists of a measuring body (1) with a number of electrical measuring points (2) which are distributed along the measuring body (1). The individual measuring points are therefore connected to an electrical conductor, which at its other end is commonly connected to a multi-pole contact(3). The number of measurement points on the water meter probe (1) depends on the measuring distance that is intended as well as the desired resolution. If the number of measuring points on the water meter probe becomes considerable, the information from the measuring points can be converted to serial information (parallel to serial conversion) (4), to minimize the number of conductors. The water meter probe is characterized by an elongated measuring body (1) and a multi-wire cable. The transition between cable and measuring body consists of a conical part (5) which prevents the water meter probe from getting stuck between cables, wires and hoses, during disassembly or adjustment.
