Here are all of our available Mechanical Level Gauges.
The Models GLL43/GLL63 Series vertical spiral gauges are a mechanically operated liquid level gauge. The gauge is 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 needle. The gauge is completely sealed so there is no risk of the tank contents leaking through the gauge header. The gauge can also be fitted with an electrical interfacing dial indicator, as well as indicators with set switching points.
The GLL28 Series is a simple, robust, mechanical liquid level contents gauge using a float to move the dial pointer via a magnetic coupling. This prevents ingress of the tank contents into the indicator capsule. The gauge may be specified as a top or side mounted variant. The gauge is supplied as standard with a 1.0 m, or optionally 0.5 m long float arm, which may be cut to suit a specific tank depth by the customer.
