Feature

●*Steel Ruler Water Level Meter* It provides a most accurate way to measure water levels. The meter is commonly used to measure the water level in wells, boreholes, tanks and water pipes, particularly suitable for the observation of groundwater level in hydro power projects and inspectors who inspect dam body infiltration line. Not only be used during construction but also as a long-term safety monitoring for a project.
●*Compact & Sturdy*The water level meter is sturdy, easy to use, and read accurately up to each millimeter. It features sus 316L stainless steel probe and resist corrosion & non-stretch tape. The Probe is depth up to 100m, ideal for measuring well level. The sensor at the tip of the probe provides consistent measurements with almost zero displacements. The tape seal plug design allows the probe to be quickly and easily replaced if required.
●*Operating Principles*The Water Level Meter uses a solid stainless steel probe, connected to durable tape. Rechargeable 9 volt battery, housed inside the reel hub, powers the Water Level Meter. 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.
●*Ergonomic Design*Standard reels are ergonomically designed for good balance and ease of use, with a stand-alone design, convenient carrying handle and an excellent brake. They are robust and smooth running. The battery is housed in a convenient battery drawer and each reel has a probe holder and brake. The reels are equipped with an on/off sensitivity switch, light, buzzer and a battery test button.
●*Support*For any equipment following the rules of transportation, storage and use within one month from the date of shipment, if its quality is found lower than the technical conditions, we are responsible for repair and replacement. However, when there has been unauthorized dismantling,the warranty will not be provided by our factory.


Description

Instruction
During measurement, after the coil has been rotated, press the power, and put the probe into the water pipe, then hold the steel ruler cable, let the probe moves down slowly.
The sounder will gives a continuous beep when the contact point touches the water surface, then can read the depth of the steel ruler at the pipe mouth, that is the distance from the underwater level to the pipe mouth .

Notes
A)When the probe touches the water, the sounder beeps, the indicator flashes, then slowly put down the steel ruler cable, in order to find out the sound carefully or the exactly location of the indicate moment, then we can read the depth from this point to the borehole.
B) The reading accuracy is depends on the timely determination of the buzzer and the indicate starting position. The measurement accuracy is depends on the operators proficiency, so the operator should practices more.

Maintenance
Due to the battery capacity, please turn off immediately after the measurement is completed! Remove the battery cover and replace the battery (9V battery, multi-meter battery).
Keep the probe and the steel ruler cable clean after use, and put the steel ruler cable neatly around the reel, and be placed in the cabinet.
Don’t bend the measuring cable , especially when it is close to the head, to avoid the cable to be damaged.
Put the probe gently to avoid severe vibration. If the probe got any problem, please send back to our factory.

Receipt and storage
Users should check whether the number of instrument are tally with the packing list, if not, please contact with our factory. The instrument should be stored in a room of -10 ~ +40 ℃. The rooms temperature is not greater than 80% with non-corrosive gas, keep the room dry and ventilated .
