Oil and solvent leaks are measured on the water surface
Area of application
Continuous separation layer height of petrochemical products on water “crude oil in drain water” or rainwater monitored in the collecting basin or oil separator shaft with the proven impedance float system controls the slide valve to the ORB for the discharge of place water in the event of an accident. The float is equipped with a rod probe with MTI on-site measuring electronics and is used in Ex zone 1 ia IIB. The signal is routed to the MAT control unit in the non-hazardous area using 2-wire technology.
The surface oil sensor detects an oil layer thickness of 1 mm or more on the rainwater.

Control units
MAT 4160
The Generalist MAT can be used for everything from level measurement to monitoring and detection. The first and second measuring circuits have the same functionality. The evaluation electronics not only serve as a power supply unit in 2-wire technology, but also contain the intelligence for data processing.
Your benefit: High cost-effectiveness and investment security thanks to a long service life.
- Universally applicable, reduces storage costs
- With 1 or 2 measuring inputs
- Fault visualization, fault messages can be set to analogue output mA output and limit value simulation
- Drainage of rainwater in petrochemical storage tanks
