Proven solutions for environmental protection

The products from our range which are designed particularly for environmental protection include our electronic flow monitors and level sensors, providing metering and monitoring for containers and pipe-work systems.

Flow monitors for liquids and gases

E-T-A flow monitors provide protection in the chemical industry, in sewage plants, and in air conditioning and water processing plants. Special Ex-approved versions are available for use in hazardous areas.

E-T-A flow monitors are suitable for all kinds of liquids, aggressive or non-aggressive, as well as for air and gases. Quality and reliability are assured by the design of the monitoring head which converts flow velocity into voltage and current values.

In our latest state-of-the-art series, signals are processed by means of micro-controllers. This enables us to meet customer requirements in modern process control with the latest sensor technology, self-test, linearisation, temperature compensation, display, analogue outputs and bus interfaces.

E-T-A level sensors: monitoring the level of liquids

E-T-A level sensors are suitable for level sensing in oil and water tanks, as well as in aggressive environments. The devices signal when the levels fall below or rise above a pre-set value. They work on the capacitive principle and have no moving parts.
