Description

The model BNA bypass level indicator consists of a bypass chamber which is attached to the side of a tank as a communicating vessel via at least 2 process connections (flange, threaded coupling or weld stub). Through this type of arrangement, the level in the bypass chamber corresponds to the level in the vessel. The float with a built-in permanent magnetic system, which is mounted within the bypass chamber, transmits the liquid level, contact-free, to the magnetic display mounted to the outside of the bypass chamber. In this are fitted, at 10 mm intervals, two-coloured plastic rollers or stainless steel flaps with bar magnets.

for further approvals see page 4

Bypass level indicator, model BNA with level sensor and magnetic switch

Through the magnetic field of the permanent magnetic system in the float, the display elements, through the wall of the bypass chamber, are turned through 180°. For an increasing level from white to red; for a falling level from red to white. Thus the bypass level indicator clearly displays the level of a

vessel without supply voltage.
