Design and applications

The function of the SGM is based on the variable area float principle.

In all cases where a dependable device is required for indicating instantaneous values and monitoring the flow in pipelines, the SGM is the obvious choice as a reliable device for measuring the flow of liquids and gases. Since the vertical position of the float is transmitted magnetically to a dial gauge, the SGM, as opposed to standard type variable area flow meters with a glass tube, is also suitable for measuring the flow of opaque media. Each device is individually calibrated to meet customer specifics and fitted with a medium specific scale.

For process control, the flow meter can be equipped with a limit value switch and/or measuring transmitter with electrical analog output.
