Rain Gauges

Our range of recording raingauges has been selected to complement our Hydro-Logic™ Weather Logger, offering several products to suit a variety of rainfall logging applications and budgets.

Our low-cost tipping-bucket gauges are manufactured in the UK by Casella and Environmental Measurements and all these gauges connect to any Hydro-Logic™ data logger using our digital bounce-free, pulse counter-timer technology, for operation as a raingauge logger. For organisations concerned with minimising the cost of maintenance and therefore the cost of ownership in the long-term, we recommend weighing-principle gauges.

Weighing gauges can operate unattended for many months and in many applications annual maintenance is all that is required, making these devices ideal partners for use with Hydro-Logic™ Timeview, which can be configured to trigger high-intensity alarms to provide early warning of flooding or CSO spills.
