- Level of clear chemicals or wasted liquids in opaque tanks, drums or underground tanks.
- Direct control of pumps, valves, alarm signals, with the use of level switches.

A float at the bottom of a stem moves a pointer inside a transparent PVC tube, outside the tank. The reading is direct through the transparent tube.

• Model FS4 Standard
The standard model is designed for tanks. For the float, the guiding tube has an
O.D. of 63 mm. The mounting is on the top of the tank, with a loose flange ND 65.

• Model FS4 fût
Model "Fût" is designed for drums and tanks of height less than 1000 mm. There is no guiding tube for the float; fitting is threaded. Reading tube comes with a graduated scale (one mark each 1 cm).

Each indicator is designed according the density of the liquid and height to monitor.
Note: liquid surface is at 70 to 80% of float height.

Option: Level switches
The pointer with a built-in magnet allows actuation of level switches BSM 501 or BRK60/32 (data-sheets 585-01 & -02).
