The devices can be equipped with a switching output, a frequency output or an analog output. In addition, a compact electronic can be selected that features a digital display, a switching output, and an analog output.

The device series is rounded off by an optionally available batching or totalizing electronic. The meter electronic indicates the momentary flow rate in the first line of the display and the partial or total flow in the second line.

A batching electronic controls simple filling tasks and similarly measures flow rates, total amounts and filling amounts. The analog output and two relay outputs can be used for further processing of the signals.
