| Status: |
in production |
|
|
Meter type |
heat, with possibility 2 external pulse devices with puse length minimally 0,2 second, and another ulrasonic flowmeter too. |
|
Manuf. Radio reading |
868 MHz only puse outputs (CE,CV), protocol communication not in planning (viz www.hydrometer.de ) |
|
Communication form for UMR
| direct connection to internal connector |
OK |
| original modules with optoRS232 |
OK |
| INFRAopto header |
OK |
| MBUS |
OK |
External universal radio module, connected to heat meter Infocal5
– this was begining |
|
Communication forms:
Standart communication goes through optoRS232 modul, optionally included to meter after moving-up upper case with electronics. Module is connected by internal connector (after moving case back) to procesor unit. OptoRS232 module is simple galvanic isolation (optocouplers), it implis possibility of direct TTL communication with Infocal with the same communication patrameters of serial transfer, like a optoRS232 modul. communication protocol Infocal5 is standart MBUS protocol, independently of modul type (it is very beatifull characteristics of INFOCAL). Meter react on universal address 254, 255, withou autoidentification of baud-rate, 4 wswitchable communication speeds.

The variant with connecting to 'multi' module suited for connecting multiple heat meters to only one radio module
The variant with connecting to original optoRS232+2xpulse INP module with possibility to conect 2 external water meters
Internal module with embedded antenna –5 dB suited in the same manner for direct radio reading, like a for communication through the retranslator
Internal module with lambda/4 whip antenna 0 dB well suited for direct radio reading, otherways the same using as embedded antenna's module
