Makes accurate depth measurements in wells, boreholes, standpipes and tanks. 

Water Level DrawDown Meter Applications

  • Measuring depth to water in wells, boreholes, standpipes and tanks
  • Monitoring drawdown during:
    • Low flow groundwater sampling
    • Well development and purging
    • Dewatering applications
    • Pumping, slug, hydraulic conductivity, step and other aquifer/well tests

Water Level DrawDown Meter Features

  • Both static water level and drawdown modes in one Meter
  • One convenient toggle makes it easy to switch between two functions
  • Uses very durable, accurately laser marked flat tape
  • Tape lengths up to 5000 ft. (1500 m)
  • Replacement tapes are interchangeable with other Meters
  • Has the same robust, submersible probe as the 101 P7 Water Level Meter

Operating Principles

The device uses a corrosion resistant stainless steel probe connected to clearly marked flat tape, fitted on a well-designed reel. It is powered by a standard 9 volt battery.

In water level mode, when the zero point on the probe enters water, an electronic circuit is completed, activating the buzzer and light. The depth to water is then read off the tape. In drawdown mode, the circuit is reversed— the buzzer and light are triggered when the probe is in air.

The battery test button can check the circuit in both water level and drawdown modes. The on/off sensitivity control allows the buzzer to be turned down in cascading water and ensures a clear signal in high and low conductivity conditions.
