Water Level Loggers

Look no further than the Heron Instruments loggers, which are proven reliable and accurate logging devices for groundwater level and temperature. For more than 25 years Heron Instruments has built their reputation by developing rugged, dependable, and accurate equipment for water level monitoring.

  • Our 1 litre slug is made for performing a 'slug test', which enables hydraulic conductivity estimation in monitoring wells. Designed to fit within a 50mm well and displace 1L of water. Custom sizes can also be made for larger wells, or multiple slugs can be used together to displace more water in the monitoring wells.
  • The Heron Instruments barLog, barometric logger is used to automatically compensate readings stored on the dipperLog for changes in barometric pressure. The barLog, with readings every 1 hour and a memory capacity of 32,000 data points,  is recommended for long term monitoring or where more than one logger is deployed withing in a 5 km radius. The dedicated, intuitive software makes the dipperLog quick and easy to program and launch. Simply recover your data, save your findings in a tabular display and graph, view both parameters side by side in a split screen. Use the Heron Instruments’ barLog alongside your dipperLog Groundwater Data Logger for the most accurate data possible. Add a barLog to your quote for the dipperLog TOUGH, dipperLog 64, or dipperLog 32. Download Brochure 
  • The dipperLog 128+ is a highly accurate groundwater data logger used by hydrogeologists, hydrologists, environmental technicians, water well contractors and other groundwater professionals. The dipperLog 128+ is a reliable and cost-effective solution to long and short-term monitoring of groundwater levels and temperature in wells, boreholes and open bodies of water. All Heron loggers are available in various deployment options: 1) Suspended Version – pull the dipperLog out of the well to download 2) Direct Read Version – enables you to do real time readings and download your data while the dipperLog is still in the well. 3) Reel Version – a portable solution, ideal for short term slug and pump testing Download Brochure 
  • The premium, highly accurate dipperLog TOUGH+ with titanium body and transducer is suitable for use by environmental technicians and other groundwater professionals in the most caustic and hazardous of environments. The dipperLog TOUGH+ is a reliable, cost-effective solution for long and short-term monitoring of groundwater levels and temperature in wells where contamination is a concern. Suspended Version: Install the logger using a suspension cord and simply pull the logger up, connect to a laptop or tablet with a P.C. Communication Cable and retrieve your data. Real time readings are not available with this option. Direct Read Version: This is the least labour-intensive model for groundwater data logging. The data logger is suspended on a direct read cable, which establishes a connection to the data logger at the wellhead. Programming, downloading, stopping and starting data collection can be done while the logger is deployed. Just connect your laptop or Windows Tablet at the wellhead. Reel Version: An ideal option when transporting your data logger from site to site for pump and slug tests or any other short-term deployment. Programming and downloading of the data is capable via the connection on the face plate on the reel. Real time readings are available with this option. barLog: A barometric logger, that is used to automatically compensate readings stored on the dipperLog for changes in barometric pressure (for absolute version). Recommended for long term monitoring or where more than one logger is deployed within a 5 km radius. Download Brochure 
  • The Heron 4-20mA Pressure Transmitter is easily integrated into an existing SCADA system, digital display and 3rd party data logger. It will provide a continuous, accurate water level reading for a wide variety of applications. A two-wire 4-20mA Pressure Transmitter current configuration is used with the Heron Pressure Transmitter which is the most widely used signal transmission for transducers in industrial environments.
    • Vented cable provides real time barometric compensation
    • Simple two-wire connection
    • Output signal is compatible with most telemetry, SCADA and PLC systems
    • High noise immunity on long cable runs
    • Wide range of supply voltage (7.5VDC-35VDC)
    • High accurate water level measurements
    • Reverse polarity protected
  • The dipperLog VENTED+ is a reliable, cost-effective solution for measuring groundwater levels and temperature in wells, boreholes and open bodies of water. The dipperLog VENTED+, incorporates a gauged transducer that measures pressure exempt from barometric influences which is ideal to use in both long and short-term monitoring. The dipperLog VENTED+ is removable from the vented cable, allowing easy field replacement. Just connect your laptop or Windows Tablet at the wellhead. Download Brochure
