The S-series have a large and easy readable dial of 120mm which is clearly visible even in a harsh and dusty industrial environment. It has two micro switch setpoints which are independently adjustable within the measuring range and they can be set for high and low flow alarms for example, to protect expensive equipment in various piping systems.
The Monitor is insensitive to surrounding magnetic fields and it combines the long-standing proven mechanical function with outstanding reliability. The S-series can also be ordered without the micro switches, designated S0-series, and is then used as a direct reading flow monitor only.
This model offers explosion proof option.
