We are a leading Manufacturer of 0.5mm tipping bucket rain gauge sensor, siphon type tipping bucket rain gauge, data logger tipping bucket rain gauge, self recording rain gauge and non recording rain gauge from Ahmedabad, India.
+-2% (upto 25 mm/Hr.),+- 3% (25 mm/hr to 50 mm/hr),+- 4% (50 mm/hr to 100 mm/hr.),+-5% for rain rate
The tipping bucket will typically be deployed in remote areas where frequent site visits are not feasible. Tipping Bucket Rain Gauge are manufactured as per IMD & HP project guidelines. The rain gauge is made such that it operates reliably and accurately under the prevailing environmental and weather conditions. All openings of the rain gauge except the collector are covered with stainless steel net to protect against any insects entering inside
It is having 203.3 mm dia. collector rim for precision measurement of Rainfall. Resolution : 0.2 mm or 0.5 mm. The body is made from Stainless Steel 316 non corrosive material with duly mirror finishing. There is a funnel to collect rainfall and divert it to Tipping Bucket mechanism. There are two buckets arranged such that one will always be UP for collection of water in it & other will be DOWN. When water in Bucket equals to 0.2 mm of rainfall, the Bucket lowers down draining out the water & other will be UP for collecting rain & so on... The Tipping Bucket calibrated in factory for 0.2 mm and do not require recalibration upon installation. The Equivalent Tipping of each Bucket can be individually micro-adjusted for re-calibration. Field maintenance should include occasional clearing of the collector (funnel) and inspection of internal mechanism to make sure it is free from insects and debris
Each Tipping will make 1 contact closure output using reed switch assembly. Any suitable display unit or datalogger having contact closure output can be used for fetching the rainfall.
Tipping Bucket comes with top insect / leaves steel wire mesh screen, mounting bracket with foundation bolts.
+- 2% (25-250 mm/hr) and +-3% (250 mm/hr to 500 mm/hr.)
0.5 mm per tip (Optional 0.25 mm / Tip)
Tipping Bucket Mechanism
Upto 600 mm / hr
Magnet and Reed Switch
8 MB ( Sufficient for more than 1 year )
The Siphon Type Tipping Bucket Rain Gauge uses a tipping bucket (cup) mechanism with siphon system, magnetic reed switch once every unit of rainfall. Every pulses by Tipping bucket is counted by Digital Data Logger having 8 MB Data Memory. The Data logging interval can be set according to requirement of site or weather condition in ints internal Memory. It can be set to 5/10/15/20/30/60 minutes. Which is sufficient for logging 390 days of data @ 30 minutes logging inverval. The Data logger consist of Real Time Clock with extra Battery backup of Lithium Battery
The Raingauge series tipping bucket Rain Gauge is sturdy constructed from durable Fibreglass body. The tipping mechanism is having very solid construction ensuring that tips are accurate and consistent in volume. The system consists of 12V SMF Battery for longer supply, 15 days battery backup The USB port can be used to transfer data from Data logger to PC / laptop using USB pen drive.
The system can easily be taken apart to clean. Debris and dirt will collect in this mechanism, thus making it essential that cleaning becomes an integral part of the maintenance program. GSM / GPRS option is also available for direct data transmit to web server / FTP server using GSM modem and SIM card without visiting the site location.
Microcontroller based Digital Rain fall indicator in mm
Fiber rasin plastic
0.2 mm per tip (0.5 mm optional)
Unlimited rainfall (Upto 600 mm / hr. intensity)
Tipping Bucket Mechanism
16 x 2 Alphanumeric
Typically five (5) years' operation
In-built battery with Solar panel for charging battery
The Data Logger Tipping Bucket Rain Gauge uses a tipping bucket mechanism that triggers a magnetic reed switch once every unit of rainfall (0.2 mm). Every pul by Tipping bucket is counted by Digital Direct Rainfall Indicator Display unit, which is continuously totalizing rainfall. There is RESET switch. After note down the rainfall reading, pressing RESET will reset the counter (resets rainfall to ZERO)
The Rain gauge series tipping bucket Rain Gauge is sturdy constructed from durable Fibreglass body with 203.3 mm diameter Gunmetal Collector rim at top for accuracy of collector area. The tipping mechanism is having very solid construction ensuring that tips are accurate and consistent in volume. All the material used in this instruments are weatherproof, non-corrosive material. The system consists of internal Battery for longer supply, which is charged by Solar panel for continuous operation of the instrument.
The system can easily be taken apart to clean. Debris and dirt will collect in this mechanism, thus making it essential that cleaning becomes an integral part of the maintenance program.
The self recording rain gauge consists of a rain collector & recording mechanism! mounted' on base. The collector has a gunmetal knife edged rim with a funnel to direct the collected rain water towards the float chamber. It has a window of 100mm x ·100mm for viewing the recording chart. It has a device to lock it to the base. A ' strong bracket is provided at the bottom of the base for anchoring it securely to the cement platform. The Collector & Base are manufactured out of glass fiber reinforced. polyester (FRP) with beautiful colour & smooth surface finish. FRP material is highly corrosion resistant, shock & dent proof, & good insulator of heat. These properties give long outdoor life & less evaporation loss of collected rain water. THE RECORDING MECHANISM CONSISTS OF Gunmetal float chamber with integral cast rests for fixing it on the base. Float with a flat guide strip at the bottom & a rod at the top for holding the ink pointer assembly
Siphon chamber with two coaxial tubes a conical brass washer, polished glass disc & a threaded cap. Brass disc with 'V' shaped opening connects the siphon chamber to the float chamber.
