Heron Dipper-T Water Level Meters With Static and Drawdown Levels

Heron Dipper-T Water Level Meter

The dipper-T2 water level meter is designed for well drillers, consultants, and hydrogeologists all across the globe.

The dipper-T2 is a rugged and dependable water level meter made from high quality materials, easy to use for a wide variety of applications. The dipper-T2 is capable of measuring both static and falling head levels. Static mode is used for measuring the depth of water in wells, boreholes and standpipes. DrawDown mode is used for measuring falling water levels during purging, well development and for low flow sampling; helping to protect your pump from damage caused by dry running.

The Heron dipper-T2 is renowned for its premium, polyethylene coated yellow steel tape accuracy in measuring depth to water. Available in your choice of either metric or engineering scale.


The highest accuracy begins with a top quality, heavy duty tape. Each tape is tested to ensure compliance with appropriate ASME standards. These tough tapes have a breaking load of over 150 kg. The tape is made from high tensile steel, ensuring resistance to stretching even at abnormal loads.

Everything on the unit from the ergonomic vinyl carry handle to the easy clean, full depth stainless steel probe has been carefully designed to give you the very best water level meter. Each unit includes a sturdy padded nylon carrying bag.

Drawdown Feature For Low-Flow Sampling:
With a touch of a button the unit changes from static to drawdown mode; a dual function unit at an affordable price.
The dipper-T in drawdown mode is ideally suited for low-flow groundwater sampling. During sampling the drawdown level needs to be monitored closely so that it does not fall below the pump inlet. If the drawdown alarm sounds then the user can quickly slow the pumping rate or stop the pump temporarily and allow the well to recover. The drawdown feature may be used for measuring falling water levels during purging and well development, helping to protect electrical pumps from damage caused by dry running.

The Well Casing Indicator Probe is used to measure the depth of metal casing in wells and boreholes from 50mm in diameter and upward. The Well Casing Indicator Probe works using magnetism. While the probe sits within the magnetic field of the steel casing, an auditory and visual signal is active. When the probe leaves the magnetic field the signal stops. Note the condition of the well for accurate readings.

The Well Depth Indicator Probe (or bottom detector) is used to measure the full depth in wells and boreholes. The Well Depth Indicator Probe uses a pressure sensitive plunger to measure the distance to the bottom of the well. When the Well Depth Indicator Probe reaches the bottom of the well, the plunger enters the probe body closing a switch, initiating an audible and visual signal at the top of the well.
