Water Level Meter,10-300m Groundwater Levels Measuring,Water Level Indicator,Well Water Depth Sounder,Electronic Water Level Gauge with Fixed Probe and Steel Tape 20m(65.6ft)

♥ Do you consistently get inaccurate water depth readings?Do you consistently make mistakes when measuring water levels outdoors?This water level gauge is accurate to within a centimeter—everyone who uses it raves about it!♥ Instructions:To measure, rotate the coil, press the power button, and gently lower the probe into the water pipe while holding down the steel ruler cable. A continuous beep from the fish finder indicates that the probe has touched the water surface, allowing you to read the depth from the steel ruler to the mouth of the pipe, which represents the distance from the water level to the mouth of the pipe.♥ Technical Specifications:Product Name: Water Depth MeterMaterials: PVC with stainless steel probeRange: 10m (32.8ft), 20m (65.6ft), 30m (98.4ft), 50m (164ft), 100m (328ft), 150m (492ft), 200m (656ft), 250m (820ft), 300m (984ft)Minimum Scale: 1mmApplicable Temperature: -20°C to +60°CPower Supply: 9V Battery (not included)♥ Package Contents:1 Water Level Meter♥ Notes:When the probe touches the water, the fish finder beeps and the indicator flashes. Carefully lower the steel ruler cable to pinpoint the exact point of indication for an accurate depth reading from this point to the hole. The accuracy of the reading depends on the timely detection of the buzzer and the indication start point, while the accuracy of the measurement depends on the operator's skill, emphasizing the importance of practice.♥ Service:If you have any questions about this nail gauge, please contact us and we will provide you with a satisfactory solution.

• 【Measurement Accuracy】: The measurement unit is centimeters, and the applicable temperature of the instrument is -20℃--+60℃. This water level meter delivers reliable and accurate readings with 1mm resolution and less than 2mm repeatability error, ensuring consistent monitoring across wells, boreholes, and reservoirs.
• 【Suitable for Various Water Measurement Needs】Effortlessly measure depths from 10 m to 300 m, with options for 10m, 20m, 30m, 50m, 100m,150m, 200m, 250m, 300m. 10-50 m use larger probe with 0.99in (25mm), 100-300 m use smaller probe with 0.6in (15mm). Please confirm the correct size for your needs before purchasing.
• 【Structure and Composition】Steel ruler water levels gauge is composed of probe, steel ruler cable, receiving system and winding reel. It features 304 stainless steel probe with built-in waterproof contacts to ensure durability and waterproof performancefor long-time use. When in use, please handle the probe with care.
• 【Operating Principles】The Water Level Meter uses a solid stainless steel probe, connected to tape measure. The water levels gauge is powered by a 9V battery, saves the trouble of connecting another power cord. When the probe enters water the electrical circuit is completed, sending a signal back to the reel where a light and clearly audible buzzer are activated. The water level is then determined by taking a reading directly from the tape at the top of the well casing or borehole.
• 【Versatile Applications】 This well water level meter sensor works for wells, boreholes, tanks, pipes, and garden ponds—suitable for groundwater gauge, pipe inspection, irrigation, drilling. A must-have reliable water level probe measurement tool for residential or large-scale projects
