BSIL-W7 Water Level Meter

BSIL-W7 Water Level Meter is used to measure the water level in well logging, boreholes or pressure tubes. The instrument consists of a steel ruler with built-in wires, probe, sound and light indicating circuit and ruler reel etc. The probe on the ruler front end has a needle water level sensor, triggers the soundlight alarm within the reel once the probe touches the water surface and indicates the depth of the liquid level from the orifice basing on the ruler scale. The ruler section adopts a dog boneshaped design and prevent effectively adhering to well logging or borehole moisture affection. The high qualified reel adopts aluminum alloy manufacture and stoving varnish coating surface features a good anti-moisture and anti-corrosion ability.

Applications
Water Level Meters are used to measure the depth of water in standpipes, wells and boreholes. The meter is simple to use and being portable, can be used at many locations such as: water levels in open boreholes, construction control and stability monitoring of dams, reservoirs and embankments, hydrological and hydrogeological investigations of water resources, stability investigations of natural and cut slopes, etc.

Operation
The Water Level Meters use corrosion proof stainless steel probes attached to permanently marked flat tape, fitted on a well balanced reel. They are powered by a standard 9 volt battery.
The probes incorporate an insulating gap between electrodes. When contact is made with water, the circuit is completed, activating a loud buzzer and a light.
The water level is then determined by taking a reading directly from the tape at the top of the well casing or borehole. A
sensitivity control allows the buzzer to be turned off while in cascading water, and ensures a clear signal in both high and low conductivity conditions.
