Tipping Bucket Rain Gauges

We are Manufacturer, Supplier, Exporter of Tipping Bucket Rain Gauges and our set up is situated in Pune, Maharashtra, India.

The Tipping Bucket Rain Gauge is sturdily constructed from FRP base and receiver funnel. The Filters in the receiver and both outlets prevent debris (e.g. leaves, dirt & insects) from entering the working parts of the instrument. The gauge is also fitted with a siphon to control and maintain a constant flow - rate into the bucket mechanism. This ensures reliable rainfall recording in even the highest rainfall intensities. The tipping mechanism is manufactured from Acrylic plastic and is ensuring that tips are accurate and consistent in volume. As algae and dirt will collect in this mechanism, as with any tipping bucket rain gauge it is essential that cleaning becomes an integral part of the maintenance program. Reed Contact Model is supplied with a single Reed Contact as a detector. This requires no power and is a simple two wire connection. This is usually the easiest to connect to PLCs and other Data Loggers. Addition of a series resistor provides protection against excessive currents. This means an indefinite life and includes standard pulse stretching. There is no 'debouncing' required as there is no 'bounce' effect with the electronic detector.The TBRG Sensor is developed as per India Meteorological Department's requirement and to match with World Meteorological Observation Standards. This product is approved & is tested as per IMD standards.
