6700 Liquid Level Indicator

The 6700 Liquid Level Indicator (LLI) is a tank side device that uses a target and gauge board to indicate product level in a bulk storage tank. This simple and reliable float and tape based product has been used for managing inventory in the oil and gas industry for more than 80 years.

Economical, Durable Design

This is the simplest measurement product on the market today. A float follows the liquid level as it changes in the tank, which then moves the indicator cable up and down the aluminum gaugeboard. This simple technology will not break your budget.

 

 

Easy-to-Read Display

Choose the units that fit your business, either in feet/inches or meters/decimeters. A large format scale is printed on a durable vinyl facing that can be seen at a distance.

 

On Your Tank

Select the installation kit suitable for your bulk liquid storage tank. We also supply many accessories, such as manway covers, inspection covers, oil seals, tank brackets and more. If you have one of our competitors’ boards we can easily upgrade the gaugeboard, float, or tape, without replacing the hard mounted tank fittings.

 

Level Alarms

Get more out of your existing liquid level indicator — Varec’s magnetic limit sensors go hand-in-hand with any tankside gaugeboard or liquid level indicator. Kits are available with one to four sensors; simply bolt each sensor to the gaugeboard at the height you need an alarm and wire them to your system.
