WHAT IS AN OMBROMETER?

An ombrometer is a device for determining the amount and intensity of precipitation with a defined collection area. The precipitate is collected via the funnel and a standardized collecting area, solid precipitates such as. B. snow, are defrosted. The collected precipitate passes through the funnel through the drop former into the self-emptying collecting vessel, where it is immediately weighed. It is not the absolute weight that is evaluated, but the weight gain from the previous measurement.

 
ADVANTAGES AND FUNCTIONS OF THE OMBROMETER

If one chamber of the collecting vessel is full, the collecting vessel tilts, empties itself and the measurement is continued in the other chamber. During the tilting process, the ombrometer performs appropriate compensation calculations . In the subsequent filter stages, influences from wind, shock and vibration are filtered out. Because of this and the funnel , the ombrometer is almost insensitive to wind. After the filtering, the measured weight increase is evaluated and, in the simplest case, output as a rain event. An ombrometer of the rain [e] series enables the measurement of every drop of the drop former with a high resolution of 0.001 mm / m² and is smaller and more compact than many other ombrometers.

15189 Precipitation sensor according to Joss-Tognini-15189

GROWN FROM EXPERIENCE …

and equipped with the properties and advantages of its tried and tested predecessors, this all-metal tipping bucket precipitation sensor (15189) is the “best in its class”! Its functionality is precisely tailored to the needs of classical meteorology and hydrology as well as semi-professional industrial meteorology. The precipitation sensor (15189), in its different versions, is an extremely economical investment for life!

RAIN GAUGE

The precipitation gauge works with a low-friction rocker (tipping bucket) according to Joss-Tognini. With other rocker measuring systems, errors occur due to incomplete dripping due to surface tension in the precipitation. However, the rocker construction according to Joss-Tognini is designed in such a way that such errors are automatically compensated .

The rocker volume is 2 cm3 (2 g) or 4 cm³ (4 g) of water. In relation to the collecting area of ​​200 cm2 (WMO standard), a rocker filling corresponds to the amount of precipitation of 0.1 mm or 0.2 mm per square meter.

When the rocker is tilted, a reed contact built into the precipitation sensor is closed. The impulse output can be scanned electronically, transmitted remotely and registered. Depending on the wiring, the signal is debounced by means of integrated electronics. The signal of the reed contact can also be made available directly, ie not debounced, if the debouncing function is taken over by a suitable data logger.

 
RAIN GAUGE WITH HIGH QUALITY MATERIALS

Due to the use of extremely weather-resistant, high-quality materials, such as a precision stainless steel rocker and an overall metal housing , the precipitation gauge 15189 from LAMBRECHT meteo has a long service life and can also be used without hesitation in extreme climatic conditions . An integrated heater ensures that the rain gauge does not ice up in winter temperatures

PLUVIOMETER / WEIGHING PRECIPITATION SENSOR

pluviometer or a weighing precipitation sensor is a device for determining the amount and intensity of precipitation with a defined collection area. Using a funnel, the precipitation is collected in a collecting vessel in a simple pluviometer so that the amount of precipitation can be read off on a scale. With a weighing pluviometer, the precipitate is formed into predefined drops, which are then weighed.

ADVANTAGES AND DETAILS OF THE PLUVIOMETER

The advantage of a pluviometer of the rain [e] series is, among other things, the continuously self- emptying collection system: If one chamber of the collecting vessel is full, the collecting vessel tilts, empties itself and the measurement is continued in the other chamber. During the tilting , the pluviometer carries out appropriate compensation calculations . The device also monitors its interior temperature and uses it to compensate for the temperature drift of the load cell. In the subsequent filter stages, influences from wind, shock and vibration are filtered out. Because of this and the funnel , the weighing precipitation sensor is almost insensitive to wind.After filtering, the measured weight gain is evaluated and, in the simplest case, output as a rain event. A weighing precipitation sensor or pluviometer of the rain [e] series enables the measurement of every drop of the drop former with a high resolution of 0.001 mm / m² and is smaller and more compact than many other pluviometers.

The weighing precipitation sensor is ideal for setting up new measuring networks as well as for supplementing existing precipitation measuring networks. The Modbus RTU interface simplifies the installation of the sensor and the integration into networks. 

WEIGHING PRECIPITATION SENSOR

With a weighing precipitation sensor, the precipitation is collected via a funnel and a standardized collecting area, with solid precipitation such as hail or snow being thawed with the help of a built-in heater. The precipitation collected in this way is shaped into predefined drops in the weighing precipitation sensor, which are then weighed in order to be able to measure or calculate the amount and intensity of precipitation.

WEIGHING PRECIPITATION SENSOR – DETAILS

If one chamber of the collecting vessel is full, the collecting vessel tilts, empties itself and the measurement is continued in the other chamber. During the tilting , the weighing precipitation sensor carries out corresponding compensation calculations. The device also monitors its interior temperature and uses it to compensate for the temperature drift of the load cell. In the subsequent filter stages, influences from wind, shock and vibration are filtered out. Because of this and the funnel , the weighing precipitation sensor is almost insensitive to wind.After filtering, the measured weight gain is evaluated and, in the simplest case, output as a rain event. A weighing precipitation sensor of the rain [e] series enables the measurement of every drop of the drop former with a high resolution of 0.001 mm / m² and is smaller and more compact than many other weighing precipitation sensors.
