Water in the connected hose creates a shared reference level. Two transparent 220 mm measuring tubes, each with a 150 mm scale, make readings easier. No batteries or electricity are required.\u003c\/p\u003e\n\u003ch2\u003eHydrostatic measuring principle\u003c\/h2\u003e\n\u003cp\u003eWhen at rest, both open water surfaces settle at the same horizontal level. This height can be marked at the reference point and the target point. Hold the measuring tubes vertically, wait for the water to equalise and always read at the same point on the water surface.\u003c\/p\u003e\n\u003ch2\u003eDimensions and handling\u003c\/h2\u003e\n\u003cp\u003eThe hose is 15 m long and has a 10 mm diameter.

Align the still water level in the first tube with the reference mark. The water level in the second tube then shows the same height at the target point.\u003c\/p\u003e\n\u003ch3\u003eWhy are the water levels not producing a stable result?\u003c\/h3\u003e\n\u003cp\u003eAir bubbles, kinks, closed tube ends or water that is still flowing can affect the reading. Open both ends, remove the air and wait for the water to equalise. Also avoid significant temperature differences between sections of the hose.\u003c\/p\u003e\n\u003ch3\u003eCan I use the water level on my own?\u003c\/h3\u003e\n\u003cp\u003eThis is possible with suitable holders. Working in pairs is usually easier: one person holds the reference tube while the other marks the target point. When repositioning the tubes, prevent water from running out of either tube.\u003c\/p\u003e\n\u003ch3\u003eHow far can I work with a 15 m hose?\u003c\/h3\u003e\n\u003cp\u003eThe usable distance is less than the hose length if the route goes around obstacles or hose is needed for the vertical ends. Plan the actual route of the hose. Longer distances can be transferred using carefully positioned intermediate marks.\u003c\/p\u003e\n\u003ch3\u003eWhen is a water level practical compared with a laser?\u003c\/h3\u003e\n\u003cp\u003eIt needs no direct line of sight between the measuring points and no electricity. This is useful when transferring a height around corners or between rooms. This alone does not establish universally higher accuracy than a laser.\u003c\/p\u003e","brand":"TOPEX","offers":[{"title":"Default Title","offer_id":64595104891229,"sku":"1045","price":60.0,"currency_code":"RON","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1068\/5520\/3165\/files\/unbekannt-11943027.jpg?v=1777921168","url":"https:\/\/brixoro.eu\/en-ro\/products\/15-m-hose-water-level-220-mm-measuring-tubes","provider":"Brixoro","version":"1.0","type":"link"}
