Water Level Instrumentation

Whether it’s a simple mechanical fox whistle, the ever-reliable Heron Dipper T, or continuous logging and telemetry devices, you will find our range of water level monitoring options here.

  • The fox whistle is the ultimate low cost tool you can use for measuring depth to water.  Our fox whistle is made from stainless steel, is 20mm in diameter and 200mm long.  Air is pushed through the hole in the fox whistle and when it comes into contact with water, it makes a whistling sound. A 30m tape on a windup reel is also available to order as well. Please Note - Maximum depth recommended is approximately 20m, otherwise you may not hear the whistle. Also, not recommended for use in noisy environments such as a busy road or noisy site, as again you may not hear the whistle.    
  • For Narrow Diameter Wells The Skinny Dipper water level meter is ideal for measuring static water levels in narrow wells, boreholes, tubes and piezometers. The slim line tape and ¼” probe enable users to take readings while the pump is still in the well, whereas wider tapes may get tangled. The premium padded carry case comes included to protect your precision instrument from the elements. The ¼” polyethylene tape, available in metric (mm) or engineering scale (1/100’), is marked with black and red graduations, making measurements easy to read in the field.
  • The water tape2 water level meter is made for drillers, consultants and hydrogeologists that are looking for an economic water level meter that does not lack in quality. The water tape2 provides accurate water measurements without going over budget. The Heron water tape2, an economical water level meter, can be used for measuring both static and drawDown levels in open bodies of water, wells, boreholes and standpipes. This low cost unit with DUAL FUNCTION capability is ideal for every project and budget. The water tape2 manufactured with the white polyethylene tape, reinforced with Kevlar is available in both metric and engineering scale. Unlike some other white tape units, the water tape2 comes with a fully pressure rated probe* and carry bag.

  • 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.        
  • The Heron H.OIL & SM.Oil interface meters are used to measure the thickness of floating or sinking hydrocarbon products (LNAPL, PSH, DNAPL), in groundwater accurately, reliably, safely & economically. The SM.Oil is essentially a smaller, lighter and mini-version of the industry standard H.Oil. Unlike other interface meters, the H.Oil and SM.Oil come with fully submersible probes. Easy to Operate with Accuracy The easy to read accurate (ASME standard) heavy duty Kynar® jacketed tape allows you to measure with confidence to 1mm resolution. Ruggedness and Dependability For dependable field use, it features an environmentally protected encapsulated circuit for safety and durability on an easily removable modular electronic panel. The field changeable probe makes your job more efficient. Save Money on Repairs & Replacements The unique flexible link between tape and probe protects the tape. Should the probe become “hung up” in the well, the link will break, saving the tape by sacrificing the less expensive replaceable probe. In addition, the core of the measuring tape used is high tensile steel with a breaking load over 300Lbs (136kg)- to further protect the instrument. The modular constructed quick change probe and electronic panel make replacing parts fast and convenient. Safety over a Wide Range of Gases The industry leading H.Oil interface meter offers you the highest protection against fire and explosion.  
  • Conductivity, Temperature & Static Levels The Conductivity Plus enables accurate measurements of conductivity, water levels and temperatures in wells, boreholes, stand pipes and estuaries where salt water intrusion and contamination levels become a concern. Conductivity can be an early indicator of change in a water system due to fluctuations of salinity in water levels. The premium padded carry case comes included to protect your precision instrument from the elements. The high tensile steel core measuring tape is tested for stretch resistance to ASME standards and is ideal for profiling up to 50˚C. An LCD screen displays conductivity values up to 80,000 µS and temperature range from 0˚C – 50˚C. The conductance temperature compensation coefficient is 2.0%. Calibration of the conductivity plus is easy using readily available 1413, 5000, 12880, 111800 uS solutions, and up to 4 calibration points can be utilised. The Conductivity Plus provides a higher range of up to 250,000 μS/cm, which is the highest conductivity range on the market.
