Introduction

The S1 Liquid Level Indicator is designed for use with a Gill Sensors Liquid Level Sensor. Liquid level within the tank is displayed in real-time via 29 super-bright LEDs, with a visible low level indicator that appears on the seven-segment display section.

At just 6mm deep, the aluminium bezel is ideal for dashboard and instrument panel installations. The level indicator is secured in place via two screws, with a simple rectangular cutout required for the recessed electronics. The level indicators are offered in blue (fuel) and red (oil) variants as standard, however other colours and custom identification labels are available on request.

S1 Liquid Level Indicators are ideal for use with regular shaped tanks, where the physical liquid level is a good representation of the volume of liquid remaining. For installations where the tank is an irregular shape the S2 Liquid Level Indicator is recommended. The S2 Liquid Level Indicator can be fully configured to allow a linear display of the tank volume, regardless of changes in tank profile.

Product Customisation

The S1 display is available as a fuel level display (anodised blue with etched 'FUEL') or oil level display (anodised red with etched 'OIL'). Other custom colour and label configurations are available on request.
