Design and function |
Compact / remote version |
|
The unit is available in a compact or a remote |
|
version with up to 30 meter distance from flow |
|
meter to transmitter. When ordering a compact |
|
(standard) version the transducer cables are |
|
premounted and ready for installation. Compact |
|
mounting is only possible up to 120 °C. The flow |
|
sensor must be isolated to protect transmitter |
|
from heat. The transmitter is available in an IP67 |
|
enclosure. |
Power supply
The standard version contains a 115 / 230 V AC mains unit including 3.6 V single battery backup in case of mains power failure. It can be retrofitted to a battery version with a dual battery pack (6 year lifetime).
Pulse output
SONO3500CT has digital output functions. Output A is MID approved and used as input for energy meter INFOCAL 9, or as input for digital systems for remote reading. Output B is preset by the factory as alarm and can’t be configured.
Items supplied |
The device can be delivered as either a |
|
compact or a remote system. |
