Page 5: Application
2 Application The device combines cutting-edge weighing technology in a very small space with a self- emptying collection vessel. The system provides excellent resolution and high precision. Even minute drops will be measured. The weighing precipitation transmitter is suited for use in meteorological and hydrological monitoring networks as well as applications in the area of environmental monitoring. -

3 Construction and Mode of Operation Measuring edge Housing Locking screw Connection for sensor Connection for heating Fastening screw Stand pipe Figure 1: Construction The precipitation transmitter measures the quantity and intensity of precipitations. The precipitation transmitter combines cutting-edge technology with a self-emptying collection vessel. -
Page 7: Measured Values And Electrical Output
3.1 Measured Values and Electrical Output The precipitation transmitter measures/calculates the following values: Quantity of precipitation (pulse) The precipitation quantity is issued in real time with a maximum resolution of 0.01mm via the pulse output. Intensity of precipitation of the last minute (RS485-interface) The precipitation transmitter performs six measurements per minute and adds these values up in a moving sum. -
Page 8: Heating
3.2 Heating For applications in regions with seasonally or permanently low temperatures, the precipitation transmitter is available in a heated version. The internal heating is divided into two parts: a funnel heating along the inner surface of the catch funnel of the precipitation transmitter melts solid precipitations and the outlet heating below the protection grille and the collection vessel prevents complete freezing of the outlet. -

Page 17: Connection Order
5.4.1 Connection Order Connections have to be carried out in the following order: 1. Connect external power connection of heating. 2. Connect sensor cable. The maximum possible distance between measuring device and data recording device depends on the interface used. The standards applicable to the values obtained with RS485 (1000 m) apply. -
Page 18: Interfaces
5.6 Interfaces The precipitation transmitter is equipped with the following interfaces: ◦ Serial interface: ◦ RS485, (half duplex), ASCII- and MODBUS RTU-protocol, ◦ Pulse output 1 precipitation: ◦ 1 galvanically isolated open collector output ◦ Precipitation output according to factory-default resolution and closing time; on request, the factory setting can be modified to customer specifications. -

It may only be used as single measuring system. (Bus operation s.h. MODBUS-RTU). When a command containing a parameter is transmitted, the parameter is checked. When it is valid, the parameter is saved and acknowledged in the “echo telegram”.

Note: The value overflow of the precipitation sum has to be considered in the calculation of the difference. The value overflow occurs at 60000g collected liquid. For sensors with a catch area of 200cm², this results in a value overflow at 3000mm. 6.4 Pulse Output Each pulse is equivalent to a defined quantity of measured precipitation. - Page 26 Note: When cleaning the collection vessel, take care to avoid damages. Do not clean the measuring system and the collection vessel with a steel brush, similar gadgets or aggressive cleaning agents.
