The mechanical level gauges GLL 43 Series
they are mounted vertically from the top of the tank so as the liquid level changes, the float follows that change and uses a magnetic coupling to transfer that motion from the float to the level indicator dial.
The gauges are completely sealed so there is no risk of the tank contents leaking through the gauges header.
The gauges can also be fitted with an electrical interfacing dial indicator, as well as indicators with set switching points.
