Explosion-proof Turbine Flowmeter SMALL-Ex® ViscoFlow series is the measuring instruments are designed for use in filled systems with water or emulsion. Depending on the design or application, the measuring instruments can be designed for system pressures up to 400 bar.

The volume flow measuring instruments can be optionally equipped with a self-illuminated display. For versions with integrated pressure or temperature measurement, up to 3 displays are installed.

For a better opportunity to use, the measuring instrument can be designed with a stepped sensor. The sensor is in a separate housing and is connected with a cable to the evaluating unit, which can be equipped with a display.

In the volume flow measuring instruments SMALL-Ex®, the measured liquid medium flows through a defined housing bore and sets the turbine in motion. The turbine is equipped with five sealed magnets. These magnetic fields are reported by an inductive, non-contact sensor to the electronics and evaluated there. The flow direction is not relevant for these volume flow measuring instruments.

Various mechanical connections are available, such as different threads, staple lock, flange, Victaulic-system or SAE-flange. Due to the construction of the nominal widths DN20 to DN32, several instruments of this size can be mounted together to build a unit.
