Water Level Gauge with 20 m Hose Dedra MW042 — water level measuring instrument

Dedra MW042 is a water level gauge supplied with a 20 m hose for measuring relative water levels and transferring level references over distance. The instrument uses a transparent hose and a visible level indicator to provide a straightforward method for establishing equal heights and transferring horizontal planes. Designed for use in construction, landscaping, plumbing and general site surveying, this water level gauge is suitable for both indoor and outdoor tasks where a simple, reliable visual water column is required.

Advantages

The transparent 20 m hose allows flexible positioning and simultaneous measurement at distant points without electronic calibration. The clear level indicator provides an easily readable water column that reduces interpretation errors when transferring levels. Lightweight and portable, the tool requires no power source and is tolerant of uneven terrain and obstacles between measurement points. Its simple design minimizes maintenance and enables quick setup for routine leveling tasks.

Suitable for

• Transferring horizontal levels on construction sites
• Aligning pipes and fixtures in plumbing and drainage work
• Landscape grading and backyard leveling
• Interior leveling tasks such as installing shelves or cabinets
• Basic site surveying where a visual reference between points is needed

Key specifications

• Hose length: 20 m of transparent flexible tubing for long-distance leveling
• Level indicator: visible water column for direct comparison of heights
• Operation: gravity-based water column system; no batteries or electronics required
• Suitable environments: indoor and outdoor use, tolerant of moderate temperature ranges when used with water
• Portability: lightweight and easy to coil for transport and storage

How to use

Fill the hose partially with water, ensuring there are no air pockets that could interfere with the water column. Place one end of the hose at the reference point and hold or fix the other end at the point to be measured; allow the water to stabilise so the columns at both ends settle to their true levels. Read the water level at each end against a fixed marker or staff to determine relative height differences and transfer horizontal planes. After use, drain the hose and coil it for storage to avoid kinks and maintain clarity of the tubing.

Usage recommendations

For best results, use clean water and avoid extreme temperatures that may cause freezing or expansion. Minimise air bubbles during filling and keep the hose straight between measurement points where possible. When working outdoors, protect the open ends from dirt to maintain clear readings and store the hose coiled in a dry place to prolong service life.
