Meteorological heated rain gauge / snow sensor
Rain-O-Matic Meteorological snow, rain and precipitation sensor
Rain-O-Matic Meteorological snow, rain and precipitation sensor with our patented unique single spoon tipping bucket is one of the most accurate and reliable heated precipitation gauges that comply with WMO standards.
For 35 years we have supplied more than 220.000 rain gauges to 41 countries on 5 continents. We deliver our products to OEM customers only and we are not competing with you for the end user. Download datasheet here.
Features and benefits
Beneath is listed the features and benefits of choosing Rain-O-Matic Meteorological heated rain gauge as your rain guage.
RAIN-O-MATIC Meteorological patented unique single spoon tipping bucket is one of the most accurate and reliable rain gauges on the market. It gives you advantages in:
- More accurate measurements
- Only one adjustment screw which makes it easy to recalibrate.
- Bucket made in POM, which is a more dismissive material and therefore makes dust and dirt not stick so easily on the spoon and maximize water release.
WMO compliant rain gauge
Rain-O-Matic Meteorological heated rain gauge complies with World Meteorological Organization standard (WMO guide no.8) such as:
- Deep funnel to avoid splash out and evaporation.
- 200 cm2 orifice angel top-ring with sharp edges.
- Drain pipe for collection of precipitation.
- Drip-rod/filter in plastic.
- Thermal safety switches on the heating elements to avoid evaporation and reduce power consumptions.
- 2 separately heating compartments.
Calibration is a very important issue for PRONAMIC and therefore all Professional rain gauges are manually calibrated. It gives you the guarantee for a very accurate measurement. Free selection of 0,1 – 0,2 0, 25 or 0,5 mm resolution at the same price. Accuracy: +/- 2%.
Our Meteorological rain gauges require minimal maintenance due to:
- Outer shell is made from ASA which makes the surface easy to clean.
- High quality plastic materials and a simple design for a very long durability (10-20 years).
Our strength is customized rain gauges for the individual customers. Logo Match - Branding of your own brand/company name on the rain gauge.
Rain gauge/Tipping Spoon
Rain-O-Matic Meteorological heated rain gauge measures the precipitation and snowfall by means of a heated copper funnel (orifice 200 cm2), which leads the water down into the single self-emptying tipping POM bucket, held in place by a hard ferrite magnet.
The magnet always exerts just enough tension to allow the measuring bucket to empty in one quick movement (less than 300 ms) and then return to its normal position, ready to once again collect precipitation. This means the counter weight always remains the same opposite to other conventional two spoons tipping bucket rain gauges.
Diagrams of intensity are available in the datasheet here.
ASA plast materials
The rain gauge is made in molded thermoplastic, also known as ASA, which has high outdoor weather ability.
ASA is extremely resistant against the sun’s UV radiation, it is frost‐ and heat resistant, standing all climatically conditions.
The product is widely used in the automotive industry as well as several other outdoor applications.
The electronic printed circuit board with individually tested and high quality reed switches protected against extreme weather conditions such as extreme frost or heat. This include corrosion from salt water due to the PCB is coated with weather-resistant varnish.
The printed circuit board comes in this version:
- PCB No. 9602 (NC—Normally closed, NO—Normally open). Terminal strip with 4 connections / 2 outlets and 2 reed switches, connected-up in series by 1 kohm and 1/4W resistor.
The Rain-O-Matic Meteorological heated rain gauge are very accurate and rugged which makes it perfect for:
- Weather stations
- Meteorological institutes
- Avalanche facilities Water works
- Wastewater treatment plants
- Hydropower stations
- Road authorities
- Skiing resorts
- Research facilities
