Abstract

Flottörfri relativ och absolut vattennivåmätarprobDet som är signifikant för denna probe är att:Probens form som 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 på kabel.Genom att avståndet mellan mätpunkterna är dubbelt så stort runt referenspunkten erhålles en linjär mätskala även runt referensläget.De mått och antal som anges på bifogad ritning är endast typiska och kan anpassas till aktuell mätning.Float-free relative and absolute water level gauge probe What is significant for this probe is that: The shape of the probe which without moving parts enables immersion in the 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 on the cable. Because the distance between the measuring points is twice as large around the reference point, a linear measuring scale is also obtained around the reference position. only typical and can be adapted to current measurement.

Description

Beskrivning Solna 12 nov -19 Flottörfri relativ och absolut vattennivåmätar probe för borrade brunnar Problem som denna probe löser. Description Solna 12 Nov -19 Floatless relative and absolute water level measuring probe for drilled wells Problems 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 of water level in wells after the pump device is installed with hoses, suspension device and electric cable to the pump.

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

Avståndet mellan de ledande punkterna beror på den upplösning som önskas och antalet ledandepunkter, ger önskat mätområde.The distance between the leading points depends on the resolution desired and the number of leading points, gives the desired measurement range.

Mellan den nedersta ledande punkten (common) 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 sänks ner till vattennivån. Efter det att indikeringen för -30 cm, -20cm, -10cm och +10 cmindikerats, lyfter man upp mätproben 10 cm. Vattennivån kommer då att ligga mellan -10 och +10cm (referensläge = Ocm). Proben är nu kalibrerad och ökning och minskning av aktuell vattennivå kandå följas.Between the lowest leading point (common) and the others, the conductivity of the water is measured. In this way, you can determine at or between which leading points the current water level is located. Relative measurement The measuring probe is lowered to the water level. After the indications for -30 cm, -20 cm, -10 cm and +10 cm have been indicated, the measuring probe is lifted up 10 cm. The water level will then be between -10 and +10cm (reference position = Ocm). The probe is now calibrated and the increase and decrease of the current water level can be followed.

Absolut mätning Kabel är märkt med längduppgift från referensläge, på lämpliga avstånd.Absolute measurement Cable is marked with length information from the reference position, at suitable distances.

Det gå då lätt att avgöra nivån på aktuell vattennivå i förhållande till annan känd punktOption 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 If the number of conductors in the probe becomes extensive, it is possible to minimize the number of wires in the cable by converting these to serial form before they are read.
