Isodaq Technology. We aim to supply you with the very best value solutions to help your organisation reduce the costs of monitoring and also improve timely on-line access to high quality measurements at your remote sites. Here you will discover some of the benefits of our innovative products and why we are the chosen supplier to numerous drainage authorities, water companies plus rivers and environmental regulators across the globe.

Company Profile

The secret of our success at Isodaq Technology is our capability to design and manufacture electronic logger and software components in-house combined with close collaborative relationships with selected international manufacturing partners who design state-of-the-art measurement sensors. In this way we are able to offer you well integrated, highly reliable yet affordable on-line monitoring and early-warning systems for a wide range of applications in the water and environmental regulatory industries. Applications which have included :-

  • Rainfall intensity logging - rainfall logger applications with storm intensity alarms
  • Weather measurement - wind and weather logging including automatic weather stations
  • Water level measurement - sensors for boreholes, reservoirs and rivers including flood warning
  • Flow measurement - open-channel flow measurement in rivers, treatment works or culverts.
  • Water quality monitoring - range of single/multi-parameter probes for surface or groundwater
  • Pump & gate status monitoring - pump status and flood gate position monitoring
  • Flood & pollution warning systems - real-time telemetry and early warning systems

Isodaq Technology is a division of the Hydro-Logic Group, established in 1985 and now employing more than 50 staff based at regional offices throughout the UK. This includes staff employed by our sister Company Hydro-Logic Services LLP which provides consultancy services in water resources, flood-risk management, hydrometry and related field services.

Distributors wanted to join the growing success story of Isodaq GPRS data loggers

We distribute our Isodaq telemetry products including GPRS data loggers to many countries around the world and welcome enquiries from potential new international partners.  During the last year we have  launched several exciting products including the new Tadpole GPRS logger range which sets new standards for reducing the costs of ownership of telemetry outstations at remote sites. Tadpole'srevolutionary design and tiny footprint enables the device to be fitted inside many tipping-bucket raingauges.

About Us

ISODAQ TECHNOLOGY is the trading name of Hydro-Logic Ltd encompassing all the staff involved in development and support of instrumentation and software systems plus the company's product sales and marketing team. We specialise in the supply of monitoring systems for the water and environmental regulatory industries with  particular capability in flow monitoring.

The ISODAQ team based in Stirling, Scotland, is an award winning product development group offering creativity and innovation, and a broad range of technical expertise to take projects from idea to successful production.  ISODAQ design the electronics, firmware, software and mechanical parts but outsource the manufacture of most components. The final testing is carried out in-house. This arrangement allows flexible production - we can produce tens or thousands of products per year.

As well as designing and manufacturing all the ISODAQ badged datalogging and telemetry products shown on this site, we also take on customised design projects for other cients or enter into collaborative ventures for specific products. A good example of this is the Hawkeye product developed in partnership with IETG Ltd of Leeds, which has won two major awards since it's launch in 2004.

Our software team in Bromyard has been responsible for the design and support of software products such as HydroLog, Rainark, Gauger and Pocket Gauger, all of which have in their time been industry-standard products in the UK for managing time-series, and/or flow gauging data in national hydrometric networks.

To complete the range of products, we also work closely with manufacturers of quality software and sensor products. We are exclusive resellers in the UK and Ireland of the range of flow meters from internationally respected manufactuers such as Quantum Hydrometrie, Teledyne RDi (US) and Mace (Australia).


Isodaq - Model Frog RX GSM/GPRS - Telemetry Data Logger

Like its namesake, FROG is an unobtrusive friend that sits quietly keeping an eye on things, ready to leap into action when there is imminent danger. Frog RX operates either as a standalone battery-powered data logger or as a telemetry logger and is ideal for rapid deployment for water resources monitoring e.g as a river level logger, flood level logger or raingauge logger. An internal GSM/GPRS modem is built onto the main logger board to provide all ...

Siemens - Model MAG 8000 - Magflow Pipeflow Meter

Designed for the water industry, the SITRANS F M MAG 8000 device is a battery powered electromagnetic pipe-flow meter that makes it easier than ever to install a reliable water meter virtually anywhere, without sacrificing accuracy or performance.


Water measurement systems & sensors for water quality monitoring

Effective water quality monitoring is the key to environmental protection of watercourses and for reliable process control and wastewater treatment.  Discharge consents under EPR regulations dictate that water quality monitoring is undertaken to ensure that consented parameters are below the consented concentrations.  Traditionally this has been done using water quality sampling methods but increasingly automatic water quality measurement sensors linked to real-time telemetry is seen as the most...

Water measurement systems & sensors for flood warning

Isodaq’s low-cost Isodaq telemetry data logger RTUs integrated with our telemetry data acquisition and alarm-message forwarding systems together provide the ideal solution for early warning of key events such as floods, pollution or CSO overflows.


Remote or Local Upgrade of Firmware Services

A major benefit of Isodaq Hawk telemetry logger technology is the facility for firmware updates. Outstation firmware updates can be applied remotely via GSM or PSTN, but also applied locally via PC serial-port comms using the Harvest Windows package (this is Isodaq's universal logger and outstation control software). If you would like us to provide firmware updates under warranty, this can be on a return-to-base basis or via remote access to an ...

Bespoke Software Development Services

We believe that the best software and database tools reflect the core functions and aspirations of an organisation, and help it to achieve its aims through efficiency, communication, and delivery. We have been producing software products and offering data migration and bespoke software services since Hydro-Logic Ltd was established in 1985. Many of these products subsequently produced have become industry standards for hydrometric data ...


Isodaq - Version TimeBase4 - Time Series Data Management System

TimeBase is the very latest time-series data management system developed by Hydro-Logic for use in environmental and industrial applications where time-series data has been collected using data loggers and in particular telemetry data loggers.

Hydro-Logic - Version Gauger2 - Analysis Rating Development System

Gauger2 Analysis is one application within the Gauger2 suite of three seperate software packages, DESKTOP, FIELD and ANALYSIS designed for managing current-meter gaugings. Gauger2 Analysis processes a dataset of current-meter gaugings for the derivation of stage-discharge rating equations. This browser operated software package can be operated independently or as a fully integrated current meter gauging and rating development system.
